Creating Linked Data

RDF graph for Eric Miller provided as an examp...Image via Wikipedia
The Nodalities blog has the post The Data Publishing Three-Step. Agree completely. Our cataloging already meets common standards, the resources for linking are becoming more common. For example, Ross Singer made this announcement yesterday.
I just wanted to let people know I've made the MARC codes for forms of musical compositions (http://www.loc.gov/standards/valuelist/marcmuscomp.html) available as http://purl.org/ontology/mo/Genres.

http://purl.org/NET/marccodes/muscomp/sy#genre

They follow the same naming convention as they would in the MARC 008 or 047, so it's easy to map (that is, no lookup needed) from your MARC data:

http://purl.org/NET/marccodes/muscomp/sy#genre

etc.

The RDF is available as well:
http://purl.org/NET/marccodes/muscomp/sy.rdf
Now all we have is the last step, just make it available.

One thing the Nodalities blog post neglects to mention is to use tools that make it simple. Druple now makes it very easy to create RDF. The lead article, Drupal: Semantic Web for the Masses in the Nodalities magazine covers that very nicely.

Connecting People and Their Work

BibApp is a tool to connect people and their research interests at an institution.
BibApp is a campus research gateway and expert finder. It matches researchers on your campus or research center with their publication data and mines that data to see collaborations, create visualizations of areas of research, and find experts in research areas. With BibApp, it is easy to see what publications can be placed on the Web for greater access and impact. BibApp can push those publications directly into an institutional repository.
BibApp allows researchers and research groups to promote research, find collaborators on campus, and make research more accessible. It also allows libraries to better understand research happening in local departments, facilitate conversations about author rights with researchers, and ease the population of the institutional repository. Finally, BibApp allows campus administrators to achieve a clearer picture of collaboration and scholarly publishing trends on campus.
BibApp is the result of a collaboration between the University of Wisconsin-Madison and the University of Illinois at Urbana-Champaign. The Illinois Informatics Institute at the University of Illinois (https://www.informatics.illinois.edu/icubed/) provided generous funding for the development of the 1.0 release of BibApp.
BibApp is a Ruby on Rails application, coupled with the Solr/Lucene search engine, and either MySQL or PostgreSQL as its datastore. It uses open standards and protocols such as OpenURL and SWORD and automatically pulls in data from third party sources such as Google Books and the Sherpa/Romeo publisher policy database. BibApp imports publication data in RIS, MEDLINE and Refworks XML bibliography formats and exports data in several citation formats (APA, Chicago, IEEE, MLA, more) via CiteProc. BibApp also provides a web services API for delivering data as XML, YML, JSON, and RDF. BibApp is released under a University of Illinois/NCSA Open Source License (http://www.opensource.org/licenses/UoI-NCSA.php).
Live installations of BibApp can be found at:
