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.
