UDFR workshop at IIPC General Assembly

With sponsorship from the Library of Congress, a Unified Digital Format Registry (UDFR) community meeting will be held in Washington, DC, on Friday, May 4, 2012, in conjunction with the IIPC General Assembly, April 30 – May 4 .

The meeting is open to all interested members of the UDFR community; space is limited, however, and prior registration is required at . (Logistical information about the General Assembly is available at .)

The UDFR meeting will include technical presentations on the UDFR architecture and code walkthroughs of the major components of its open source technology stack, including OntoWiki, RDFAuthor, Virtuoso, Zend, PHP, Apache, and Noid; code walkthroughs; and a review of the four main ontological models: OntoWiki system configuration, UDFR user profiles, UDFR class and property ontology, and UDFR data. The intent of this meeting is to share a technical understanding of the UDFR platform to facilitate its transition from a funded project to a community supported resource.

The tentative meeting agenda is:

A testing version of the final UDFR codebase, holding a complete export of PRONOM data as of February 22, 2012, is available for evaluation at . Along with the final acceptance testing we are still working on the user documentation. To get started, click the “UDFR – Start Here” link in the “Select Knowledge Base” pane. Information can then be found by entering a search term in the “OntoWiki” pane, or using the ontology browser in the “Navigate: Classes” pane. The left and right arrow icons permit you to ascend and descend the class hierarchy. Clicking on a class name displays all instances of that class. To see all file formats, for example, descend the hierarchy to “Abstract Base” > “Abstract Product” > “Abstract Format” and then click “File Format”. The 846 formats are then shown in the paged result set in the “Resource List” pane.
