Watching the Google Analytics Real-Time dashboard for the first time was mesmerizing. As soon as someone visited a site, I could see what page they were on. For a digital collections site with a lot of images, it was fun to see what visitors were looking at. But getting from Google Analytics to the image or other content of what was currently being viewed was cumbersome. The real-time experience was something I wanted to share with others. I'll show you how I used a WebSocket service to create a real-time interface to digital collectionsviews and search queries.
In the Hunt Library at NCSU we have some large video walls. I wanted to make HTML-based exhibits that featured viewer interactions. I'll show you how I converted Listen to Wikipedia [1] into an bring-your-own-device interactive exhibit. With WebSockets any HTML page can be remote controlled by any internet connected device.
== PeerLibrary – open source cloud based collaborative library ==
* [http://mitar.tnode.com/ Mitar Milutinovic], UC Berkeley, mitar.code4lib at tnode.com
* Not presented or attended code4lib before
[https://github.com/peerlibrary/peerlibrary PeerLibrary is a new open source project] and a cloud service providing collaborative reading, sharing and storing. Users can upload publications they want to read (currently in PDF format), read them in the browser in real-time with others, highlight, annotate and organize their own or collaborative library. PeerLibrary provides a search engine to search over all uploaded open access publications. Additionally, it aims to collaboratively aggregate the open layer of knowledge on top of this publications through public annotations and references user will add to publications. In this way publications would not just be available to read, but accessible to the general public as well. Currently, it is aiming at scientific community and scientific publications.

== Teach your Fedora to Fly: scaling out your a digital repository ==
*[mailto:acoburn@amherst.edu Aaron Coburn], Software Developer, Amherst College
In some contexts it's possible -- and desirable -- to manage content in a more streamlined, lightweight way, with a minimum of fuss and technical infrastructure. In this presentation I'll share a simple MVC-like architecture for managing video content for playback on the web, which uses a combination of Apache's mod_rewrite module and your server's filesystem structure to provide an automated approach to video content management that's easy to implement and provides a low barrier to content updates: friendly to content creators and technology implementors alike. Even better, the basic method is HTML5-friendly, and can be integrated into your favorite content management system if you've got permissions for creating templates.
In the presentation I'll go into detail about the system structure and logic required to implement this approach. I'll detail the benefits and limitations of the system, as well as the challenges I encountered in developing its implementation. Audience members should come away with sufficient background to implement a similar system on their own servers. Implementation documentation and genericized code will also be shared, as available.
== Managing Discovery ==
I'll be talking about things like cache management, reverse proxies, publish/subscribe servers, WebSockets, responsive design, asynchronous processing, and keeping complicated stacks up and running with minimal effort.
==Implementing Islandora at a Small Institution== *Megan Kudzia, Albion College Library*Eddie Bachle, Albion College IT**No previous Code4Lib presentations Albion College (and particularly the Library/Archives and Special Collections) has a variety of needs which could be met by an open-source Institutional Repository system. Several months and lots of conversations later, we’re continuing to troubleshoot our way through Islandora. We’d like to talk about what has worked for us, where our frustrations have been, whether it’s even possible to install and develop a system like this at a small institution, and where the process has stalled. As of right now, we do have a semi-working installation. We’re not sure when it will be ready for our end users, but we'll talk about our development process and evaluate our progress.''Contributions also by Nicole Smeltekop, Albion College Archives & Special Collections'' == PhantomJS+Selenium: Easy Automated Testing of AJAX-y UIs == * Martin Haye, California Digital Library, martin.haye@ucop.edu** Previous Code4Lib Presentation: [http://code4lib.org/conference/2012/collett Beyond code: Versioning data with Git and Mercurial] at Code4Lib 2012 (Martin co-presenting with Charlie Collett)* Mark Redar, California Digital Library, mark.redar@ucop.edu Web user interfaces are demanding ever-more dynamism and polish, combining HTML5, AJAX, lots of CSS and jQuery (or ilk) to create autocomplete drop-downs, intelligent buttons, stylish alert dialogs, etc. How can you make automated tests for these highly complex and interactive UIs? Part of the answer is PhantomJS. It’s a modern WebKit browser that’s “headless” (meaning it has no display) that can be driven from command-line Selenium unit tests. PhantomJS is dead simple to install, and its blazing speed and server-friendliness make continuous integration testing easy. You can write UI unit tests in {language-of-your-choice} and run them not just in PhantomJS but in Firefox and Chrome, plus a zillion browser/OS combinations at places like SauceLabs, TestingBot and BrowserStack. In this double-team live code talk, we’ll explain all that while we demonstrate the following in real time: * Start with nothing.* Install Selenium bindings for Ruby and Python.* In each language write a small test of an AJAX-y UI.* Run the tests in Firefox, and fix bugs (in the test or UI) as needed.* Install PhantomJS.* Show the same tests running headless as part of a server-friendly test suite. * (Wifi permitting) Show the same tests running on a couple different browser/OS combinations on the server cloud at SauceLabs – talking through a tunnel to the local firewalled application. ==New Technologies, Collaboration, & Entrepreneurship in Libraries: Harnessing Their Power to Help Your Library== * Stephanie Walker – swalker@brooklyn.cuny.edu* Howard Spivak – howards@brooklyn.cuny.edu* Alex - Alex@brooklyn.cuny.edu Academic libraries are caught in budget squeezes and often struggle to find ways to communicate value to senior administration and others. At Brooklyn College Library, we have taken an unusual, possibly unique, approach to these issues. Our technology staff have long worked directly with librarians to develop products that meet library, faculty, and student needs, and we have shared many of our products with colleagues, including an award-winning website, e-resource, and content management system we call 4MyLibrary, which we shared for free with 8 CUNY colleges, and also an easy-to-use book scanner, which has proven overwhelming popular with students, faculty, other librarians, and numerous campus offices. Recently, motivated by budget cuts, we decided that what worked for us might interest other libraries, and working with our Office of Technology Commercialization, we started selling 2 products: our book scanners (at half the price of commercial alternatives), and a hosting service, whereby we could host and support 4MyLibrary for libraries with minimal technology staff. Both succeeded, and yielded major benefits: a steady revenue stream and the admiration and serious goodwill of our senior administration and others. However, this presentation is neither a basic how-to, nor an advertisement. With this presentation, we hope to spur a conversation for broader collaboration, especially regarding new technologies, among libraries. We all have some level of technical expertise, most of us are struggling with rising prices and tight budgets, and many of us are unhappy with various technology products we use, from scanners to our ILS. We believe – and can demonstrate – that with collaboration, we can solve many of our problems, and provide better services to boot. == Identifiers, Data, and Norse Gods == * Ryan Scherle, [http://datadryad.org Dryad Digital Repository], ryan@datadryad.org** previous Code4Lib talk [http://ryan.scherle.org/papers/2010-2-code4lib-HIVE.ppt HIVE: A New Tool for Working With Vocabularies], at Code4Lib 2011. ORCID and DataCite provide stable identifiers for researchers and and data, respectively. Each system does a fine job of providing value to its users. But wouldn't it be great if they could link their systems to create something much more powerful? Perhaps even as powerful as a god? Enter [http://odin-project.eu/ ODIN], The ORCID and DataCite Interoperability Network. ODIN is a two-year project to unleash the power of persistent identifiers for researchers and the research they create. This talk will present recent work from the ODIN project, including several tools that can unleash the godlike power of identifiers at your institution. Current tools include:* Metadata generator tool: allows repository staff to create DataCite metadata with embedded ORCIDs.* Claiming tool: assists researchers in claiming their work within the ORCID system. * ORCID-feed: includes a list of ORCID works on any web page.* ODIN's HAMR: assists in populating a DSpace repository with ORCIDs. Based on work from a Code4Lib hackathon! == Armed Bandits in the Digital Library == * Roman Chyla, [http://labs.adsabs.harvard.edu/adsabs/ Astrophysics Data System], rchyla@cfa.harvard.edu** Previous Code4Lib: [http://code4lib.org/conference/2013/chyla Citation search in SOLR and second-order operators] Many of us are using the excellent Lucene library (or SOLR appliance) to provide search functionality. These systems contain number of features to adjust relevancy ranking of hits, but we may not know how to use them. In this presentation, I'll present the available options - eg. what is the default ranking 'Vector space model, what are the alternatives (eg. BM25) and what are the other options we have to tweak and adjust the ranking of the hits (eg. boost factors, functions). But even if we know how to deploy these adjustments and tweaks, we are still left in dark. We do not know whether the change we've just rolled out had a significant (statistically significant) effect or maybe it was just a waste of time and resources? A/B testing is one option, but there may be a much better one - so called "Multi-Armed Bandits Approach". And in this talk I'd like to show how we are experimenting with this strategy to adjust [http://labs.adsabs.harvard.edu/adsabs/ ADS search engine]. == Building Worker Queues with AWS and Resque == * Eric Rochester [http://scholarslab.org Scholars' Lab], erochest@virginia.edu* Scott Turnbull [http://aptrust.org/ Academic Preservation Trust], scott.turnbull@aptrust.org A common task in larger systems is to be able to process large input files automatically. Often users can drop those files into a shared directory on AWS or on NFS or another shared drive. Those files need to be processed and potentially integrated into a system. This task has come up recently in the University of Virginia libraries in allowing users to add GIS data to the system and in setting up a system for the Academic Preservation Trust (http://aptrust.org/) that ingests files and resources into the preservation system. This system is built by loosely coupling a number of different technologies. This allows us to easily interoperate and communicate between different system and programming environments. Because the interfaces are well defined, it’s also fairly simple to switch out technologies as the requirements of the system change. The process is fairly simple: First, a Ruby daemon monitors an AWS S3 bucket that others can upload new files into. This daemon creates a Resque status task, adds a marker for the task in a database, and continues monitoring. Second, Resque mediates incoming job requests and routes them to the appropriate workers which may be in Java, Go, or Ruby. The diversity of technologies that Resque can manage allows great latitude to leverage the appropriate tool for a specific job. While processing, it updates the status for that job and coordinates processing with other jobs. Finally, a page that is integrated into a larger Rails app provides a novice-user-friendly view of the status of the workers and allows basic tasks such as restarting the job. This architecture allows us to swap in the technology that best fits each part of the process, and it makes it easier to maintain the system. We use this to integrate and coordinate between tasks handled in Java, Ruby, and Go, and it provides an effective way to interoperate with these programming languages and the respective strengths that they bring to this system. == Sustaining your Open Source project through training == * Bess Sadler (Stanford University Libraries) and Mark Bussey (Data Curation Experts) will discuss their experiences developing and delivering training for Project Hydra. Topics covered:* Working practices for developing training materials* Sharing the work when there are no dedicated resources* Inviting community (and student) input to create higher quality content* Strategies to keep training docs up-to date* Strategies to make training materials available to the widest-possible audience* Using surveys (Survey Monkey) to assess the effectiveness of your training program ==Piwik: Open source web analytics==* Kirk Hess, University of Illinois at Urbana-Champaign (kirkhess@illinois.edu)** (Code4Lib 2012: [http://code4lib.org/conference/2012/hess| Discovering Digital Library User Behavior with Google Analytics]) While Google Analytics is synonymous with Web Analytics, fortunately today we have many other good options, and one option is Piwik, [http://piwik.org| piwik.org] a simple to install, open-source PHP/MySQL application with a tracking script that will sit alongside Google Analytics tracking the usual clicks, events and variables. In this presentation, I'd like to cover the usual analytics topics and also cover what makes Piwik powerful, such as importing and visualizing web logs from any system to incorporate both past and future data, easily tracking downloads, and the ability to write your own reports or dashboard. The visitor log data is stored securely on your own server so you have control over who looks at the data and how much or how little to keep. With an active and helpful developer community, Piwik has the potential for analytics which makes sense for libraries, not e-commerce. == Next Generation Catalogue - RDF as a Basis for New Services == * Anne-Lena Westrum – digitalutvikling@gmail.com* Benjamin Rokseth * Asgeir Rekkavik * Petter Goksøyr Åsen Oslo Public Library has converted the entire MARC-catalogue to RDF via the self-made conversion tool MARC2RDF. [http://digital.deichman.no/data.deichman.no/| data.deichman.no], the enriched RDF version of the library catalogue including its authority files, forms the basis for two different mashups; The Active shelf and the Book recommendation database. The RDF catalogue is linked with various content and the dataset is updated daily to account for additions, deletions and changes made in the MARC catalogue. [http://vimeo.com/68687814| The Active shelf] is a physical touchscreen device that makes use of open source software, RFID technology, RDF data and external web service APIs to provide information about any library book a patron is curious to know more about. The Book recommendations database stores book recommendations written by library staff from all over Norway and links them to the RDF-representation of the MARC-catalogue. ==Economics of Scale: Thinking about Metadata Quality and Completeness for Fun and Profit==* William Hicks, University of North Texas (William.hicks@unt.edu) The UNT Libraries Digital Collections constitute three internet gateways, The Portal to Texas History, UNT Digital Library, and the Gateway to Oklahoma History, making available to the public a wide range of materials, from photographs and newspapers, to dissertations and recordings of music ensemble performances. The collections disseminate over 500,000 unique items, that were used over 9 millions times last year and with growth trends in both areas shows no signs of slowing. As the size and scope of our collections has grown, so to has a pressing need to think clearly about the quality of our metadata, the completeness of our records, and the most efficient way of doing metadata entry. Not surprisingly there have been a few things written on the subject and so over the last few months we’ve started writing new code and getting the infrastructure of our metadata editing system to a place where we can begin to test these ideas on our ever expanding dataset. What kinds of questions are we looking to answer, and what types of tools are we building? That’s what this talk will be all about, but here are a few ideas to ponder: * What kinds of tools have we built, or can we employ to standardize data entry and aid the user in their input needs?* How close does a metadata record come to a “completeness” standard? What does that even look like? What are the implications when we look at such a standard at scale?* If we can identify what we think a “quality” metadata record “is”, historically speaking, how close do we get to that ideal? * Does an item’s history matter? Can we quantify it and locate value in change through time?* What are the economic costs of metadata entry? If we have enough quantifiable measures about the types of objects in our systems, and we can profile our data entry personnel, what can this say about optimizing staff time and return on investment?* What sort of priorities are we setting for ourselves when we treat all items as equal, when clearly some types of materials get vastly more use by the public.* Finally what kinds of analysis tools might we develop to gauge our overall metadata “health,” to steer projects, or to ultimately improve our systems for our end user’s needs? Most of our questions are still quite open ended, and honestly we are just getting started down this road. But as digital collections grow, and library budgets realign or shrink, it becomes increasingly important to back up our assertions and opinions with numbers, and find more efficient ways to work with the resources we have. ==A Different Kind of Search: Query Analysis of Map Search==* Zoe Chao, University of New Mexico (zoechao@unm.edu)* No previous Code4Lib presentation Map searches are an increasingly important part of university and library websites. In 2012, The University of New Mexico (UNM) replaced its original PDF based campus maps (http://iss.unm.edu/PCD/campus-map.html) with an interactive map search based on the free Google Maps API. In addition to the basic map information such as streets and building outlines, we added search capabilities and categories for browsing (http://search.unm.edu/maps/). From November 2012 to September 2013, we logged about six thousand search instances on the campus map search. This data suggests that map searching presents a fundamentally different kind of search for users which results in a large number of failed searches that return empty or misleading result sets. In this presentation we will briefly describe the development and current implementation of the UNM map search and our data collection of search queries. We then discuss the some surprising findings based on the data analysis. For instance, a large number of map queries include specific room numbers, which indicates some users perceive the search to include buildings' floor plans. This result suggests that we need to truncate numbers from queries in order to return correct building locations. Finally we will talk about the insight we gained from the data and our next steps toward the data driven interface design. ==More Like This: Approaches to Recommending Related Items using Subject Headings==* Kevin Beswick, NCSU Libraries (kdbeswic@ncsu.edu)** No previous code4lib presentations With a significant portion of the collection at our new Hunt Library being housed in an automated storage and retrieval system, several of us at NCSU Libraries have begun looking at ways to replace and improve upon the classic shelf browsing experience in order to make it easier for patrons to browse related materials. Our goal is to mimic popular services like Amazon and Netflix, which utilize recommendation engines to make it easy for users to find items similar to a particular item of interest. While there have been previous efforts in libraries to recreate this experience using circulation or call number data, we are currently investigating algorithms that focus on use of subject headings. Use of subject headings as an alternative can be particularly helpful in the case of electronic materials that do not always have call numbers or circulation data. In this talk, I will share: * Details of the proposed algorithms * How these algorithms were quickly and easily implemented using Solr. * Our evaluation process and its outcomes in terms of the effectiveness of the algorithms.* How this has (or could) impact presentation of recommended items in our discovery layer. == Questioning Authority: building a ruby gem to facilitate UI interactions with varied controlled vocabularies == * [[User:Mhbussey|Mark Bussey]], Data Curation Experts, mark@curationexperts.com At a recent Hydra meeting, developers from five different institutions all realized that they had similar needs to support various types of UI fields based on a multiple of internal and external authorities and controlled vocabularies. Their goals was to develop a tool that let them meet these needs in ways that minimized the need for custom coding for each vocabulary. During an intense three-day working session, they minted the initial release of the [https://github.com/projecthydra/questioning_authority/blob/master/README.md questioning authority] gem. The talk will cover both how cross-institutional development helped speed development and how the gem can be used for accessing both external vocabularies like LCSH and LCNA and for presenting internal vocabulary lists. Although the developing institutions are all Hydra implementers, the gem itself doesn't have any Hydra dependencies and can be used in any Rails or Blacklight based application. == Building Hydra, a framework; a community == [mailto:justin@curationexperts.com Justin Coyne] Project Hydra contributor / Data Curation Experts More than just a repository, the [http://projecthydra.org Hydra Project] is a community of cultural heritage institutions dedicated to pooling knowledge and resources. It is a completely open source project that has grown continuously for over 5 years. Within this vibrant community, a number of conventions and practices have emerged that we believe will benefit others attempting to cultivate support for their community oriented projects. The Hydra Project is now a mature initiative which is producing shareable, reusable and customizable components as well as complete repository solutions. In a time of tight budgets and growing demand for improved systems, we believe that "the Hydra way" is the exemplar case in the library community for how to work across institutions to deliver high quality services to our patrons. This talk will cover both the technical and human processes that have sustained Hydra's continued development and growth. From [http://www.ohloh.net/p/projecthydra Ohloh.net]In a Nutshell, Project Hydra...* has had 8,364 commits made by 64 contributors representing 60,733 lines of code* has a codebase with a long source history maintained by a very large development team with stable Y-O-Y commits* took an estimated 15 years of effort (COCOMO model) starting with its first commit in October, 2009 ending with its most recent commit 7 days ago == JQuery XML Editor == Presenter: Ben Pennell, UNC Chapel Hill Libraries (bbpennel@email.unc.edu)no previous C4L presentations The jquery.xmleditor is a portable jquery widget developed by the University of North Carolina at Chapel Hill Libraries for the purpose of simplifying the description workflow for existing objects in our digital repository. It does so by adding context and structure informed by an underlying XML schema. Even more generally, it creates and modifies XML documents in your web browser. It can be found here, including a live demo:[https://github.com/UNC-Libraries/jquery.xmleditor] Features include:* Graphical editor mode for displaying and modifying XML elements* Text editor mode for directly modifying the underlying document (using the Cloud9 editor)* Contextual, schema driven menus for adding new elements, subelements and attributes in both the graphical and text editing modes* Fully javascript and CSS based, jquery widget* AJAX submission of document modifications* Ability to export XML document to a file in web browsers that support it* Keyboard shortcuts for navigation and other operations* Standalone tool for building JSON representations of XML schemas In our own implementation, the tool communicates with a Fedora based SWORD 2 enabled repository to receive the starting MODS document and to submit changes. But it's all XML in the end, and includes options for exporting to file or submitting to any endpoint that accepts XML. This presentation will include an overview of the development process, technologies and issues involved, as well as a brief demonstration of the editor in use. It will also touch on the tool backing the editor which constructs JSON objects from schemas. == Visualizing Library Resources as Networks ==* [mailto:matthewmiller@nypl.org Matt Miller] New York Public Library, NYPL Labs.**No previous C4L presentations Library resources are typically presented linearly in the form of a catalog search results page or an iterative list of subjects, books, special collections, etc. This talk explores the possibilities created when thinking of library resources as interconnected networks. We will look at the progress of a project to visualize NYPL resources such as catalog subject headings[1][2] as a network. We will also look at moving beyond visualizations into building network interfaces, such as our archival access term explorer[3] prototype. [1] [https://dl.dropboxusercontent.com/u/4070829/catalog-viz-subjects/seadragon.html Catalog Subject Headings Visualization] [2] [https://dl.dropboxusercontent.com/u/16562899/timelapse6.mp4 Time lapsed catalog network] [3] [http://archives.nypl.org/terms Archival access term explorer prototype.] == Island or Archipelago? Reducing Repository Redundancy at University of Toronto Libraries == *[mailto:sallain@utsc.utoronto.ca Sara Allain], Special Collections Librarian, University of Toronto Scarborough*[mailto:kbabcock@utsc.utoronto.ca Kelli Babcock], Special Projects Librarian, Special Projects Librarian, University of Toronto Scarborough*No previous Code4Lib presentations This session will address a big issue in library technology – the creation of redundant repositories across large, multi-library institutions. We will discuss an ongoing collaboration at the University of Toronto: the development of Collections UofT, an Islandora/Drupal instance intended to support the special collections projects of UofT's community, faculty members, and 44 libraries. We will look at: *Successful communication strategies imperative to fostering collaboration among project stakeholders*Complications caused by legacy repositories and varying metadata standards*Negotiating branding and usability requirements for disparate projects*Focused outreach to generate community buy-in*Defining the roles and responsibilities of the repository's community*Generating a proactive response to the above issues through documentation, issue reporting, and standardized Memoranda of Understanding As the University of Toronto Libraries continue to facilitate and develop digital projects, it is vital that our systems be both centralized and flexible, able to meet the needs of various collaborators across a wide range of subject areas. Collections UofT is our first step towards a brighter digital future for special collections at the University of Toronto. == So You Think You Want to Be a DPLA Service Hub?: Building a Statewide Repository System for the Commonwealth == * Steven Anderson, Boston Public Library (sanderson@bpl.org) **No previous presentations at national Code4Lib conferences (excluding one lightning talk in 2013)* Eben English, Boston Public Library (eenglish@bpl.org) **No previous presentations at national Code4Lib conferences Built upon the Hydra stack, the [https://search.digitalcommonwealth.org Digital Commonwealth] repository system houses a variety of digital content from over a dozen Massachusetts libraries. In addition, we also harvest metadata via OAI-PMH from many other institutions throughout the state that lives alongside hosted content in (relative) harmony. This talk will discuss the development of our repository, with an emphasis on the specialized use cases that are involved in creating a system to serve as a DPLA service hub. As a DPLA hub, we have many contributing institutions using many different systems (Omeka, DSpace, CONTENTdm, Fedora/Hydra, etc.) with OAI feeds that we need to harvest from and convert into our data storage format. Come hear about our journey into the madness of what people can put into their metadata records and our data normalization strategies for adding this content to our system. We'll also cover: * Inherited design structure: Each OAI source has its own metadata nuances, and creating a "single script to rule them all" is out of the question (even if the records use the same schema and/or come from the same system). It is, however, possible to use good object-oriented principles to first cover general cases and then adjust for each institution's metadata style. In addition, our system uses content models that inherit from more basic implementations that make dealing with various types of heterogeneous content in our system much less painful. * Interface design: How do you create an online metadata editor for world's widest user base, from septuagenarian volunteers to academic librarians? How do you design a search interface that keeps content from a small historical society from getting lost in a sea of material contributed by statewide organizations? We've got answers. * Useful libraries and techniques: '''> 120'''. That's how many date formats our system currently supports when reading from an OAI feed. What libraries did we use to help parse that information? How are we generating thumbnails for various types of content when none are provided? We'll cover useful libraries and gems that make the hub developer's life worth living again. ==Getting a New Website Without Losing the Old One== *Angie Ballard, NCSU Libraries, (aballard@ncsu.edu)**No previous Code4Lib presentations*Charlie Morris, NCSU Libraries, (cdmorris@ncsu.edu)*Erik Olson, NCSU Libraries, (eolson@ncsu.edu)**No previous Code4Lib presentations The NCSU Libraries last website redesign launch was in August 2010. The stated goal then was to position our website and our organization for a future of evolving through more iterative changes and agile workflows. This year’s latest evolution to a responsive designed website carried out this approach. We made incremental changes that retrofitted the face of the existing desktop website to be responsive-ready while simultaneously developing a fully-responsive Drupal theme. Staff and end-users saw incremental changes starting with flattening the visual design, followed by font and spacing changes, modularizing existing page elements, and finally new responsive headers, footers and page layouts. This approach allowed us to re-use large portions of existing code, and to provide a more gradual shift for styaff and end-users. This iterative design process allows for testing and internal evaluation along the way. It also highlights IA and Content Strategy issues to be addressed in later projects. We will talk about how scoping the project to these technical changes while largely maintaining the existing site IA, content, and visual design elements has a number of advantages with a few challenges. ==Solr faceted title/call-number/heading browse with inline cross-references== * Michael Gibney, University of Pennsylvania (mgibney@pobox.upenn.edu) * No previous presentations at national Code4Lib conferences I would like to present an overview of recent development at the University of Pennsylvania library leveraging Solr/Lucene data structures to allow true browse (e.g. for Call Number, Title, Author, and Subject) with inline cross-references, over arbitrary subsets of records (as restricted by filters/facets/queries). Challenges addressed in development include: * 1. Providing for efficient normalized term sorting (with highly-configurable normalization) while preserving term case and formatting for term-centric display. * 2. Allowing record-centric display of results retrieved via term index (effectively allowing sorting on multi-valued fields). This point applies mainly to Call Number and Title browse.* 3. Inline display (with associated record counts) of cross-references for heading terms (as of Nov. 8, 2013, implemented only for Author browse using LC authority file as represented in VIAF, but designed to be readily extended to apply to subject headings, and multiple, query-time configurable authority schemes). The solution that will be presented is native to Solr/Lucene (an extension of UnInvertedField), and is related to the approach suggested by Jonathan Rochkind at: http://bibwild.wordpress.com/2010/06/05/note-to-self-more-ideas-for-browse-search-in-solr/. It is extremely lightweight, with the only dependencies being already supplied by Solr/Lucene on the classpath. It is flexible and easily configured via Solr configuration files. Being related strictly to Solr/Lucene, it should be front-end agnostic and equally applicable in VUFind, Blacklight, or any other framework using a Solr backend. The resulting functionality is in production at http://franklin.library.upenn.edu/. It is still under heavy development, and questions/comments/criticism would be welcome. The source code has not been released open source, but hopefully that will change in the near future. ==Queue Programming -- how using job queues can make the Library coding world a better place== *Birkin James Diana, Brown University (birkin_diana@brown.edu)**I've given one or two C4L 20-minute talks and a few lightning ones over the years In 2007 we built a system that dumped certain user web-requests for books into a database for offline-processing triggered via cron. We wanted to make the magic happen live, but knew it would take too long. Thus we created, sort of accidentally, a kind of old-fashioned static procedural job queue. Over the years we we've been repeatedly impressed with how useful and robust this unintended architecture has been, and it fostered thinking about using real job queues in Library workflows. Fast-forward to the present. We now are using _real_ job queueing, in production, for parts of the functioning of Brown Digital Repository. We've also used it for ingestion scripts, and plan to move more lots more code to this architecture. I'd like to share & show:* our lightweight rq/redis job queueing setup* how using job queues can speed up workflows via using multiple workers* how job queueing can make workflows more robust, especially by simplifying failure handling* a way we've smoothly avoided race-conditions that can occur in concurrent-programming* a technique for using task-processing job queues to simplify complex workflows rq: http://python-rq.org redis (python): https://pypi.python.org/pypi/redis/ == How Can a new NISO Recommended Practice Help Me? ==* [mailto:nettie@niso.org Nettie Lagace], Associate Director of Programs, National Information Standards Organization (NISO)* No previous C4L presentations (except for lightning talks in 2012 and 2013) Two new NISO recommended practices are on their way to publication and hopefully, uptake and adoption: a specification for Open Access Metadata and Indicators (OAMI) and a Protocol for Exchanging Serial Content (PESC). Who are the stakeholders and potential users of these? How are they expected to be applied? This presentation will cover specification and implementation details for these two community-developed recommendations and utilize them as examples of consensus standards completed in a short turnaround time period. The NISO Open Access Metadata and Indicators recommendations are a mechanism for transmitting the access status of scholarly works: peer reviewed articles published in subscription and hybrid journals, material available in institutional repositories, or any other such applicable material. Clear information regarding re-use rights must be included in this communication; “open access” on its own may not convey potential downstream uses. In addition, embargoes often come into play regarding availability of material. The NISO Protocol for Exchanging Serial Content attempts to address an entirely different conundrum: how can digital files which make up serial content (which may well include text and images or other associated data) be successfully transmitted from partner to partner while including metadata requirements for description and organization of content? This information is needed for those who archive and preserve content, as well as those who may aggregate it, index it, or convert it to other uses. As more serial content is shipped to disparate stakeholders for all manner of potential uses, a common protocol will prevent local reinvention of the wheel. Standards are entities that users in many communities often love to hate (http://xkcd.com/927/), but when projects need to be completed in a timely, cost-effective way and when interoperability with other entities is key, (almost) everyone will look to see if there is an existing standard or best practice in existence to help them get started. In order for standards and best practices to gain acceptance and adoption, it is critical for their development process to involve as many potential stakeholders and eventual user communities as possible. == A reusable application to enable self deposit of complex objects into a digital preservation environment== * Jill Sexton jill@email.unc.edu, UNC Chapel Hill Libraries* Mike Daines daines@email.unc.edu, UNC Chapel Hill Libraries* Greg Jansen count0@email.unc.edu, UNC Chapel Hill Libraries Jill gave a lightning talk once, otherwise no previous C4L presentations Patron-initiated ingest of complex, multi-part objects into digital preservation environments remains a challenging problem for many libraries. In this talk we discuss how we approached this problem at UNC Chapel Hill. UNC Chapel Hill Libraries is the developer of the Curator’s Workbench, (download: http://www2.lib.unc.edu/software/ GitHub Repo: https://github.com/UNC-Libraries/Curators-Workbench/wiki) an open-source collections preparation and work flow tool for digital materials. In response to the demand for patron-initiated ingest into our preservation repository, we extended the functionality of the Workbench, creating a module that enables easy creation of web deposit forms suitable for varying content types. The forms use dictionary and crosswalk mapping components to map the input fields to the MODS schema. Form designs also include explanatory text and designation of required fields. The forms work in tandem with a server-side form-hosting application, which can be configured to put uploads and MODS records onto a filesystem, or to deposit materials into a repository via SWORD. The forms feature simplifies the creation of deposit forms, shifting form design from software developers to curators, who have greater familiarity with both the depositor community and with descriptive standards. We also shift metadata creation to the content creators, who have the most knowledge of submitted materials. We will demonstrate how this process works for the submission of Studio Art MFA theses. These complex deposits consist of a narrative description of the artwork in addition to up to 20 video- or image-based files documenting of their work, and associated metadata for each file. In addition to preserving MFA projects in a stable environment, this procedure gives graduate students greater control over the submission and description process and provides online access to MFA Art Theses and supporting works. Additionally, the project has invited discussions with MFA students about the preservation of their personal archives. Our talk will address how these tools could work within other digital preservation environments == Leveling Up: Migrating Multiple DSpace Repositories to a Multi-tenant Configuration. == * Aaron Collier, Digital Repository Services Manager, Systemwide Digital Library Services, California State University (acollier@calstate.edu)**No previous presentations at national Code4Lib conferences.* Carmen Mitchell, Institutional Repository Manager, California State University San Marcos (cmitchell@csusm.edu)**No previous presentations at national Code4Lib conferences (excluding Ask Anything sessions, 2012 & 2013) In 2007 the California State University system started a project to provide a hosted institutional repository system for it’s individual campuses using the DSpace repository system. With limited technical staffing dedicated to the project, the result was a single server hosting seventeen individual and separate instances (including tomcat, databases and indexes). This lead to resource instability and lack of parity between versions, features and support. In order to overcome the shortcomings of this structure, a custom multi-tenant configuration was developed using the DSpace platform. This posed several technical challenges related to campus branding, authentication and deposit workflows. During the development and testing of the multi-tenant structure of DSpace for the California State University system, constituent campuses continued to digitize works and create metadata in anticipation of a reliable system to insert these works. This created a situation where several campuses have created a lot of content and are looking for time saving measures for DSpace ingestion in order to continue work on the digitization projects. Development of a SWORD interface for bulk submission presented an attractive opportunity to provide a portal for bulk submission while avoiding the bottleneck of the provided method of FTP and DSpace scripting. Aaron Collier will talk about the technical challenges, and Carmen Mitchell will discuss the institutional needs: captioning, access copies vs display copies, workflow issues like batch uploading, embargoes, etc. == Curate Cloud: The role of cloud computing in expanding the impact of digital curation == *Erik Mitchell (http://erikmitchell.info) University of California, Berkeley*Jimmy Lin (http://www.umiacs.umd.edu/~jimmylin/) University of Maryland, College Park Digital curation skills are a multidisciplinary and pressing need in public, academic and corporate environments (Yakel, 2007 336). By 2018, the United States will have a shortage of 140,000 -190,000 people with the deep analytical skills needed to manage large holdings of digital assets (Manyika et al., 2011). At the same time our information organizations will increasingly rely digital assets in making effective decisions (Ibid.). Despite advances in digital curation technologies, institutions create far more information than they curate in large part due to a gap in skills and perceived financial and technical barriers to entry (Heidorn, 2008). These barriers can seem insurmountable for smaller and under-represented information and cultural heritage institutions. However, new cloud computing based digital curation technologies reduce many of the financial and technical barriers so that the greatest challenge remaining is a need for updated skills and digital curation competencies. Our information and cultural memory institutions require a new generation of professionals engaged in the preservation of digital resources and prepared to deploy curation tools that are not dependent on local technology infrastructure. In order to develop these competencies, Curate Cloud, a project being led by Dr. Jimmy Lin at the University of Maryland, College Park seeks to educate the next generation of information professionals using a curriculum integrated, cloud-based virtual learning environment. The environment, designed using Amazon Web Service infrastructure and deployed in a “zero-configuration” environment lowers barriers of entry to students when learning about new technologies and cultivates a new level of cloud-based IT literacies in these students. This project draws on the successes of similar programs and pushes further by developing and deploying a novel cloud-based, open source virtual research and learning environment (VRLE) that embraces the on-demand, self-service model of cloud computing and features cloud-based curation tools that will enable the exploration of digital curation across the education, library, archive, and museum (LIS/LAM) community. The presentation will focus on the research findings from the use of the VRLE in Library and Information Science education arenas as well as the challenges and opportunities that relate to delivering complex IT instruction using cloud computing platforms. The codebase for the VRLE is available at https://github.com/mitcheet. This project is supported by the Institute for Museum and Library Services and Amazon Web Services through the Amazon Educational Research program. Resources*Heidorn, P. B. (2008).

Sites more closely resemble full-blown applications, rather than static information resources. We see an opportunity for libraries to adhere to the same design principles used by popular websites, to create a more intuitive and enjoyable user experience. In our presentation, we will discuss the results from usability testing after a website redesign in 2012 (library.buffalostate.edu), our guiding design principles, and showcase some of our solutions that enhance user experience, such as responsive web design, unified searching (Knowledge Base, Summon, website documents), and transitional interfaces. Frameworks can be exploited to significantly reduce the time needed to develop powerful and engaging web applications. For example, we can use motion and transitional interfaces to help convey the sense of “space” in web design. The goal is to create an engaging experience to draw our users in. When this is achieved, it encourages usage and creates an enjoyable place that is more than just a tool, but also a place for discovery. == Responsive Web Design - A Paradigm Shift == * Jenny Brandon, Web Designer/Librarian, Michigan State University Libraries (jbrandon@msu.edu) No previous presentations at Code4Lib RWD is the biggest paradigm shift in web design in the last decade. This presentation will begin with a brief overview of responsive web design (RWD), elements of RWD, what types of frameworks are available and why you should choose one. Examples of library websites that have already implemented RWD will be analyzed to compare and contrast design methods. The remainder of the presentation will provide details on the Michigan State University Libraries' implementation of responsive web design using the Drupal Omega theme, and solutions adopted to transform an existing, fixed width library web site to a responsive design. Topics included:* flexible grids* media queries* mobile first* images* design considerations* collaboration == The Smithsonian Transcription Center == eChing-hsien Wang, Branch ManagerLibrary and Archives Systems InnovationsOffice of the Chief Information OfficerSmithsonian Institution In 2013, the Smithsonian Institution - the largest library, archive, museum and research center complex in the world - launched transcription.si.edu, the first release of the Smithsonian's Digital Volunteers platform. With the ambitious goal to engage varied audiences, enrich collections and enable discovery in ways never before imagined, the Transcription Center enlists the "crowd" to transcribe millions of pages of handwritten documents from across the Institution's vast and diverse collections. We will share our goals, strategies, and experiences as contributors and developers of this collaborative initiative among librarians, archivists and museum curators. Design, workflows, user analytics, templates, and discoveries will be demonstrated and discussed for formats as varied as botanical specimen files, diaries, ledgers, field notebooks, letters, and photographs. We will also showcase the benefit of using open source technology in building our system architecture and we will share our technical challenges and lessons learned along the way. Ching-hsien Wang has not presented at Code4Lib conference before, but have participated in other conference presentations before. [[Category:Code4Lib2014]][[Category:Talk Proposals]]
