Changes

In summer 2010, the Center for History and New Media at George Mason University, supported by an NEH Summer Institute grant, gathered 12 'digital humanists' for an intense week of collaboration they dubbed 'One Week | One Tool: a digital humanities barn raising.' The group -- several of whom hang their professional hats in libraries and most of whom were previously unacquainted -- was asked to spend one week together brainstorming, specifying, building, publicizing, and releasing an open source software tool of use to the digital humanities community. The result was Anthologize, a free, open-source, plugin that transforms WordPress into a platform for publishing electronic texts in formats including PDF, ePub, and TEI; in other words, a "blog-to-book" tool. This presentation will focus on how One Week | One Tool addressed the challenges of collaborative open source development. From the perspectives of two library coders on the team, we will describe and provide lessons learned from the One Week development process including: how the group structured itself without predefined roles; how the one week time frame and makeup of the group -- which included scholars, grad students, librarians, museum professionals, instructional technologists, and more -- influenced planning and development decisions; the roles of user experience and outreach efforts; the life of Anthologize since the end of the week; and thoughts on what a one week, one 'library' tool could look like.

VIVO is an open-source semantic Web application that enables the discovery of research and scholarship across disciplines at an institution. Originally developed from 2003-2009 by Cornell University, in September 2009 the National Institute of Health's National Center for Research Resources made a grant to the University of Florida [http://viviovivo.ufl.edu], Cornell University [http://viviovivo.cornell.edu], Indiana University Bloomington [http://vivo.iu.edu], and four implementation partners to use VIVO to create a national network for scientists[http://www.vivoweb.org]. This network will allow researchers to discover potential collaborators with specific expertise, based on authoritative information on projects, grants, publications, affiliations, and research interests, essentially creating a social network for browsing, visualizing, and discovering scientists. This talk will give an overview of the technical underpinnings of VIVO, describe how it integrates with the larger semantic Web, sketch out the plans for enabling discovery across the national network of VIVO sites, and explore the role of libraries in implementing VIVO at all the partner sites. Additionally we will demonstrate some experiments in federated searching that have been undertaken by the VIVO network and the NIH funded Clinical and Translational Science Awards (CTSA) consortium network of networks. == Mass Moves with Worldcat APIs ==* Sam Kome, Claremont Colleges Library, sam.kome at cuc dot claremont dot edu Claremont needed to perform a mass evaluation of item level records to facilitate large scale collection moves and de-accession. Our de-accession criteria, for example, include that 3 or more copies of any book must be available in the 50+ libraries in our Link+ network. We addressed our requirements with the help of the OCLC Worldcat Search and xID APIs and a couple simple python scripts. The process was ultimately a success. We will present our approach, code, and the lessons learned as we discovered limits inherent in the APIs and in our own coding (in)experience. Bonus sub-topic: the use of OCLC Work ID to identify and coalesce alternative ISBNs.  == A Simple Algorithm for User Query Classification & Resource Recommendation ==* Josh Bishoff, University of Illinois, bishoff2 at illinois dot edu One of the longstanding problems in library services is how we might automatically direct users to the most appropriate personnel, databases or facilities to meet their information need. Utilizing the faceted navigation features of various next-gen catalogs, we can efficiently & very accurately assign subject domains to user search queries.  For example: if a user searches “Gallium Arsenide” in the library discovery layer, we can first broadcast this query to a suitably large OPAC and receive the following subject distribution: -Engineering & Technology: 45% -Physical Sciences: 21% -Education: 9% …and so on.  By leveraging the cataloging efforts that have classified large collections, we can efficiently classify queries with a high rate of accuracy. By applying this approach to the library discovery layer, we can offer users tailored result sets from subject-specific A & I services. We can also recommend subject specialists & most appropriate campus libraries. This presentation will discuss the technical challenges of implementing such a system and the trouble with mapping traditional subject classifications to non-book resources (databases, people, buildings, etc.). The dangers of ''incorrect'' automatic query classification will be discussed, along with strategies to combat this. A functional system will be demonstrated and code will be made available. == Beyond Sacrilege: A CouchApp Catalog ==* Gabriel Farrell, Drexel University, g@grrawr.comAt Code4LibCon2008 Dan Scott gave us a taste of yummy CouchDB, a document-oriented database with a RESTful JSON API (http://couchdb.org/). Since then, CouchDB has passed the 1.0 mark and landed on desktops, the cloud, and mobile devices. With the advent of CouchApps (web apps served directly from CouchDB) applications can be built that are as easy to install as the replicating of databases (which is super easy!). I'll discuss the advantages and challenges in designing a CouchApp to be used as a catalog, repository, or directory of resources. Some things are made fairly simple, such as site templating, the outputting of documents in different formats, and the attachment of binary objects to documents. Some things, like document versioning and the modeling of data, are a little trickier, but still straightforward. And some things, such as granular authentication and the integration of search, are tangled enough to produce some head-on-wall banging. But hey, take it easy. It’s time to relax. Check out some code at http://github.com/gsf/catlg. == (Yet Another) Home-Grown Digital Library System, Built Upon Open Source XML Technologies and Metadata Standards ==* David Lacy, Library Software Development Specialist, Villanova University (david dot lacy at villanova dot edu)We have recently rearchitected our homegrown digital library utilizing an all-XML framework. The system is comprised of a data repository residing in a native XML database (eXist-DB), a metadata editor constructed using a Java-based XForms processor (Orbeon Forms), and a series of services for image manipulation, OCR processing and OAI-PMH serving. In this talk, I will detail our workflow process from scanning to online publishing, demonstrate the software's flexible configuration and features, and how these steps allow rapid digital preservation and online access. Oh, and it's open source, so I'll show you where to get it as well. ==Programming Latent Semantic Analysis for Large Digital Corpora==* Wally Hooper, Indiana University (whooper@indiana.edu)* Kirk Hess, Indiana University (kirhess@indiana.edu) The Chymistry of Isaac Newton Project [http://www.chymistry.org http://www.chymistry.org] is publishing one hundred eighteen alchemical manuscripts written by Isaac Newton, thirty-two of which are now publically available using TEI and Unicode encodings, and served using the eXtensible Text Framework (XTF) engine [http://www.cdlib.org/services/publishing/tools/xtf/]. The National Science Foundation has funded a three-year project (2009–12, #0620868) to develop computational tools for the analysis of the alchemical language in Newton alchemical corpus. This project is applying computational tools from the fields of computational linguistics, information retrieval, and network sciences to mine and analyze Newton’s manuscripts.  One technique, Latent Semantic Analysis (LSA), has been used by the project to create a set of tools to discover the semantic structure and organization of the corpus of text, and has discovered shared passages, phrases, and technical vocabulary across the corpus. We thought many projects with tei data might want to do LSA, but may not know how. We’ll discuss creating tools for LSA to analyze tei encoded text using xsl, perl, php, a mathematical/statistical software package (e.g. Matlab), and having a supercomputer handy is helpful but not required! We'll walk through our method for chunking text, building a term document matrix, executing singular value decomposition and outputting that data as correlated document pairs and in Graphml format so it can be analyzed in a network analysis and vizualization tool (e.g. Network Workbench)[http://nwb.slis.indiana.edu]. == Adventures In Implementing an Extended FRBR Model ==* PaulBen McElwain, Digital Library Program, Indiana University (pbmcelwa at indiana dot edu)The Variations/FRBR Project (http://vfrbr.info) has developed an implementation of an extended FRBR/FRAD conceptual model. The model encompasses the entities defined in FRBR along with some further entities from FRAD, the attributes defined for those entities, and the relationships between the entities. One extension to the FRBR model is through the addition of some entity attributes needed for MARC attributes important to collections of recorded music. But the most interesting, and challenging, extension (from a data model perspective) is the addition of a structured set of properties for the attributes of the entities, and properties for the entity relationships. The place of publication/distribution, for instance, can include properties for type, jurisdiction, normalized value, and source vocabulary, all in addition to the string value of the place. The model was defined in XML Schema and then implemented in a Java class structure with a relational database for persistence. The implemented data service currently supports a user search application, data exports in multiple structured formats (FRBR XML, RDF/XML), and is also designed to support an interactive cataloging interface. The presentation discusses the model designs developed, the technologies considered, and the implementations produced. This presentation should be of interest to other projects considering complex models of shared hierarchies implemented across XML Schema, Java, and relational data stores (via JPA). == Web Services and Library Systems == * Denis Galvin, Rice University, dgalvin at rice dot edu* Mang Sun, Rice University, mang dot sun at rice dot edu Web Services are ideal for ingesting and reformatting information. Whereas traditional Library systems like the ILS are rigid, Web Services are flexible. New interfaces can be created to display both catalog records and patron services. Item information can be integrated into third party systems like discovery layers. Web Services also represent an industry standard approach to systems integration. They offer the opportunity to bring together library operations with business systems. Currently Rice University is experimenting with Web Services for its mobile OPAC. Two interfaces have been created, one for catalog searching and one for patron services. They are lightweight and ideal for mobile devices. In this session we will talk about how libraries can and might use Web Services now and in the future. == GIS on the Cheap == * Mike Graves, University of North Carolina at Chapel Hill, gravm at email dot unc dot edu Using a few tools that you probably already have laying around your library I'll show how OpenLayers [http://www.openlayers.org/] can be used to create a dynamic interface for browsing and searching your digital collections geographically. With very little effort Solr can be made to serve up results directly into OpenLayers creating all sorts of mapping possibilities. With a little more effort a Postgres database can handle complex polygon searches [http://dc.lib.unc.edu/ncmaps/search.php]. I'll talk about how we're developing a lightweight GIS framework to provide a new user experience for interacting with a number of our collections in unique ways. == Building an Open Source Staff-facing Tablet App for Library Assessment == * Jason Casden, NCSU Libraries, jason_casden at ncsu dot edu * Joyce Chapman, NCSU Libraries, joyce_chapman at ncsu dot edu  Many libraries currently produce manual headcounts or activity counts for physical spaces in order to better understand patron needs as well as the use of spaces and services, but struggle with the difficulties of collecting data on more than one aspect of use, as well as organizing and analyzing the resulting data. The availability of tablet devices, such as the Apple iPad, has created an opportunity to simplify and encourage the collection of fine-grained data about the use of library physical spaces. The streamlined collection and centralized management of space usage data could also enable more sophisticated and rapid quantitative assessment methods that would significantly reduce the technical barriers for librarians to employ space usage data for assessment. This talk will present a library assessment and software development perspective on the creation and utility of an open source tablet-based tool for collecting and analyzing data about the use of library physical spaces. Building on recent experience developing web-based and native-iPhone library apps, we will discuss complicating implementation-related issues such as platform dependence, intermittent network coverage (data caching), and centralized data synchronization with multiple collectors. HTML5 and co-evolving technologies (specifically, Web SQL client-side storage) can be utilized to balance the various advantages of web-based apps with the performance of native apps, but implementation choices can directly impact both the types of data that can be collected and the cost of adoption of an open source release. Finally, we will use an early prototype of this tool to demonstrate some new assessment possibilities. == APPLICATIONS AT THE HEART OF A NEW PUBLISHING ECOSYSTEM == * Rafael Sidi, VP Product Management, Elsevier (r.sidi@elsevier.com) During the last decade, computing developments in information discovery have had a significant impact on the research breakthroughs that enhance our society. In the course of thousands of interviews with researchers, developers and industry influencers, we uncovered trends that are shaping lean research globally – workflow efficiencies, funding pressures, government policies and global competition. We also looked at key trends defining the future of web – openness and interoperability, personalization, and collaboration and trusted views, and saw an opportunity to create an ecosystem that empowers the scientific community to innovate, create and discover applications that leverage scientific literature to improved their search and discovery process. This session explores this new ecosystem that enables developers, researchers and research institutions to develop applications that leverage public domain and licensed content. We will talk about a platform that enables collaboration with the scientific community- researchers and developers- on solutions that target specific researcher interests and workflows. We will explain how publishers can offer their content through APIs and how publishers and platform providers can present developers with application building tools. This ecosystem will create a channel where developers can collaborate with researchers in developing new applications. These same publishers and platform providers have an opportunity to serve as the host of the new scientific knowledge ecosystem that is evolving. This fresh approach in scientific publishing would set a new paradigm in the way research information is discovered, used, shared and re-used to accelerate science. == Enhancing the Mobile Experience: Mobile Library Services at Illinois ==  * Josh Bishoff, University of Illinois, bishoff2 at illinois dot edu The University of Illinois Libraries launched a mobile interface in Spring 2010 that includes a custom mobile catalog layer built on top of VuFind ([http://m.library.illinois.edu]). It allows patrons to request books for delivery, to browse the local and CARLI consortium catalogs, and access account information for renewal & checking hold status. This presentation will focus on new features designed to add value for the mobile user, such as adding Google map links to catalog records, offering current information for campus bus stops, and automatic device detection for users accessing the full-sized library gateway from their mobile device. I’ll discuss how developing for the mobile context, and talking to mobile users, has informed the further development & improvement of library web services overall. == Reuse of Archival Description for Digital Objects == * Jason Ronallo, NCSU Libraries, jason_ronallo at ncsu dot edu In order to deal with the modern records explosion, archives have devised methods of processing and describing materials at a broad level, rather than at the item-level. This has culminated in what’s becoming a widely adopted approach to archival processing called "More Product, Less Process," where less fine-grained descriptive metadata is created. Except for highly valued materials which may still receive detailed archival description--think Thomas Jefferson's letters--this approach usually does not enable item-level discovery through an archival finding aid. However, it does make collections more readily available and helps repositories move through backlogs of unprocessed collections. Some in the profession have begun to advocate for a similar approach to the digitization of archival and manuscript materials. A growing trend in digitization is the large scale digitization of collections, where the creation of discovery-enabling detailed descriptive metadata for every object is traded for the rapid access to large swaths of collections.  Reuse of archival description for digital objects can help streamline that workflow as well as improve access. What is meant by reusing archival description for digital objects? What does it look like in practice? What new tools can be developed to support this approach to descriptive metadata? This talk will be an exploration of the interplay of archival description and descriptive metadata for digital objects. The focus will be on the tools and challenges in automating this workflow. Examples will draw from the work at NCSU Libraries with the Special Collections Research Center and include coverage of currently used tools, including locally-developed open-source, as well as future directions for development. Topics covered will include:* Necessary preconditions and conventions for this to work* Reuse of archival description from EAD XML for digital objects with simple tools* Generation of stub descriptive metadata records for digital objects* The continual refresh of metadata in the access layer throughout its lifecycle* Later enhancement of (select?) stub records* Reuse of enhanced digital object description in finding aids* Future directions? These emerging practices present challenges for potential change to:* Archival description and practice* Encoded Archival Description* Tools for archival description (e.g. Archon and Archivists’ Toolkit)* Identifier schemes and resolvers* Search and discovery interfaces for public access to collections* Search engine optimization ==Chicago Underground Library’s Community-Based Cataloging System== * Margaret Heller, Chicago Underground Library/Dominican University (mheller@dom.edu)* Nell Taylor, Chicago Underground Library (nell@underground-library.org) http://www.underground-library.org (until November 15, you will need to add /catalog to see the actual catalog) We have developed a unique cataloging and discovery system using Drupal, which we eventually hope to provide as a standalone module that any organization can implement as both a technical and theoretical template to start an Underground Library in its own city. Chicago Underground Library (CUL) is a replicable model for community collections. It uses the lens of an archive to examine the creative, political, and intellectual interdependencies of a city, tracing how people have worked together, who influenced whom, where ideas first developed, and how they spread from one publication to another through individuals.  Cataloging is done by members of the community, and so the system is designed to be intuitive for non-librarians. Our indexing method captures every single contributor (authors, editors, typesetters, illustrators, etc.) and catalogers create exhaustive folksonomy lists of subjects so that users can see how publications are linked by threads of influence. Users are able to search all of the individuals and subjects, click on contributors’ names and find everything else they’ve worked on throughout their careers, look on a map at where each publication came from and see what’s been published in their neighborhood, and also provide their own historical notes and additions to any catalog entry. Many of the publications in our collection have incomplete data sets because the people who made them never expected them to wind up in a library. We will be proactively reaching out to people in the community to share their knowledge of different publications in the catalog. For instance, they will contribute stories about where a magazine might have been distributed, who we’re missing from the masthead, where the publisher’s office might have moved to, which publications hosted readings together, etc. Our catalogers will use these contextual comments to glean more metadata for the catalog entry, but will leave up all the comments and anecdotes as part of the record. In effect, we want to create a social network that builds a library catalog, and vice versa. At Code4Lib, we will present our current system, discuss the challenges we face, and our future development plans. == Practical Relevancy Testing == * Naomi Dushay, Stanford University Libraries (ndushay at stanford dot edu) Evaluating search result relevancy is difficult for any sizable amount of data, since human vetted ideal search results are essentially non-existent. This is true even for library collections, despite dedicated librarians and their familiarity with the collections. So how can we evaluate if search engine configuration changes (e.g. boosting, field analysis, search analysis settings) are an improvement? How can we ensure the results for query A don’t degrade while we try to improve results for query B?  Why yes, Virginia, automatable tests <i>are</i> the answer.  This talk will show you how you can easily write these tests from your hidden goldmine of human vetted relevancy rankings. == LibX 2.0 and the LibX Libapp Builder == * Godmar Back, Virginia Tech, godmar@gmail.com* Brian Nicholson, Virginia Tech, brn@vt.edu LibX is a platform for delivering library services that require a client-side presence, such as toolbars, context menus, and content scripts. These services integrate library-related resources (links, results, tutorials) into those web pages your users use when they don't go through the library's portals. While LibX 1.5 was mostlyused as a toolbar to represent a library's OPAC, LibX 2.0's focus is on simplifying the creation and distributionof content scripts, which we call LibApps. The LibX Edition Builder allows librarians, even those whoprefer not to program, to independently create and distribute LibX editions for their user communities. In a similar vein, the LibX LibApp Builder allows librarians to independently create and manage LibApps for their user communities and share them with others. This talk will discuss the design and implementation of the LibApp builder. We will also show how LibApps can be created to link the user's web experience tomodern discovery systems such as Summon in a smart and non-obtrusive way. == Describing Digital Collections at the Free Library == * Daria Norris, Free Library of Philadelphia, norrisla at freelibrary dot org The Free Library of Philadelphia has developed a Digital Collections content management system and search engine to describe the scholarly and historical items we are digitizing and making available on our web site. This application has evolved into a highly customizable way of setting up the metadata requirements of each individual collection while also conforming to the Dublin Core standard. The collections are diverse and include scans of medieval manuscripts, historical photographs of Philadelphia, Pennsylvania German fraktur, automobile reference photos and more. Development has also included the integration of authorities like the Getty Thesauri and the LOC's Thesaurus for Graphic Materials in a library that can also be used in other applications. I'll also discuss our future plans for the project. == Lessons from the Hydra Community: cultivating a large, distributed, agile, open source developer network == * Matt Zumwalt, MediaShelf & Hydra Project, matt.zumwalt at yourmediashelf dot com* Bess Sadler, Stanford University, Hydra Project & Project Blacklight, bess at stanford dot edu When we set out to create the [http://wiki.duraspace.org/display/hydra/The+Hydra+Project Hydra framework] in 2009, we knew that building a strong developer community would be as important as releasing quality code. By August 2010 when we released the Beta version of [http://wiki.duraspace.org/display/hydra/Hydrangea Hydrangea] (the Hydra reference implementation) Ohloh already rated our committers as "one of the largest open-source teams in the world" and placed it "in the top 2% of all project teams on Ohloh." [see [http://www.ohloh.net/p/hydrangea/factoids/3944567 ohloh.com]] In the 3 months following that release, the number of active committers jumped even higher and the number of subsidiary projects quadrupled. This early success is the product of a concerted, collaborative effort that has incorporated input from many participants and advisors. Over these first 18 months of work on Hydra, we have cobbled together a formidable list of principles and best practices for developers and for our whole community. Many of these best practices easily translate to any development effort. They are especially applicable to distributed open source teams using agile development methodologies. Building and sustaining a community is an ongoing learning process. We have already learned a great amount -- most Hydra participants agree that working on this project has made us better at our jobs. We would like to share what we have learned thus far and get feedback about where to go from here. == Opinionated Metadata (OM): Bringing a bit of sanity to the world of XML Metadata == * Matt Zumwalt, MediaShelf & Hydra Project, matt.zumwalt at yourmediashelf dot com [http://rubygems.org/gems/om Opinionated Metadata] (OM) grew from discussions at Code4Lib 2010. It's now an integral component in the [http://wiki.duraspace.org/display/hydra/The+Hydra+Framework+and+its+Parts Hydra Framework]. Unlike most XML solutions, which start from schemas and build outwards, OM allows you to start from the natural vocabulary that emerges in user stories. Based on the terms that show up in those user stories, you can use OM to create a Terminology that maps each term to nodes in schema-driven XML. This Terminology then serves as a Domain Specific Language (DSL) for your code to rely on. Using that Terminology, you can: * Generate absolute and relative xpath queries for each term * Generate complex xpath queries for nested terms (ie. query a mods document for the "first name" of the second "person" entry OR query for all of the "person" entries whose "role" is "creator")* Validate xml documents against a schema (if one is associated with the Terminology)* Query an xml document for all values corresponding to a given term* Update the values in an xml document corresponding to a given term* Insert new nodes corresponding to a given term into an xml document* Generate solr field names appropriate for indexing a term OM borrows some characteristics from the XUpdate Language and is in part inspired by XForms. It is also strongly influenced by the agile, user-driven development methodologies of tools like Ruby on Rails. It puts the strengths of these technologies at your disposal in flexible, maintainable ways. Internally, OM works as an extension to Nokogiri (a complete Ruby wrapper for the libxml2 and libxslt libraries). It gives you access to the full power of those underlying libraries, including a complete XPath implementation, while transparently handling the idiosyncrasies of those libraries and the XPath language for you.  While OM is just a library, it can be used in a web application to create, retrieve, update and delete XML documents. Within Hydra, we have implemented a full stack that uses OM to read XML documents, populate an HTML form, accept updates via a REST API, and update the XML accordingly.
