1. 3rd (or 4th) NETWORKED KNOWLEDGE ORGANIZATION SOURCES/SYSTEMS WORKSHOP DL ‘00 San Antonio, TX June 7, 2000

2. Purpose  Bring together knowledge organization source developers  Work across the various groups -- ontologies, thesauri,classification schemes, etc.  Discuss and support best practices related to using these sources in networked environments  Provide a “breeding ground” for collaboration

3. Building a Community  Ad hoc group of vocabulary developers -70 members from 10 countries -Humanities, sciences and social sciences -Annual workshops at ACM DL, periodic dinner meetings at ASIS; Web site (UCSB), listserv (CNI); listserv archive (OCLC) -www.alexandria.ucsb.edu/~lhill/nkos  Two main activities -Protocol for searching and retrieving from distributed knowledge organization sources -Metadata content standard for KOSs

4. Protocol  Querying and retrieving from a networked knowledge organization source  Allow browsers and clients to access sources for which it has no previous knowledge  Work done at California Resources Evaluation System (CERES) and the National Biological Information Infrastructure  Have developed a protocol with RDF that requires a driver at the KOS site  Will work but not generalizable enough  Looking instead at LDAP

5. Content Standard Background  Working group established after 1998 NKOS workshop in Pittsburgh  Data elements needed to describe a networked KOS for use by any browser/client  Based on previous work by Linda Hill (UCSB) and Mike Raugh (Interconnect Tech.) (Draft 1)  Draft 2 issued November 1998; some updates made from last year’s meeting  Still a work in progress

6. Two Sub-Activities  Knowledge Organization Source Registry –Based on content standard –Self registry system –Building environmental registry as a pilot  Taxonomy of knowledge organization sources –Distinguishing characteristics of value to the user –Behavior in a networked environment
