News and Announcements

DCMI/NKOS Task Group established

2009-12-21, A new Task Group has been established under the name DCMI/NKOS Task Group that targets to develop a Dublin Core Application Profile for KOS (Knowledge Organization Systems) resources based on the work of the NKOS group. This Task Group is led by Marcia Zeng of the School of Information and Library Science at Kent State University, and Gail Hodge of Information International Associates, Inc. (IIa) who both have become members of the DCMI Advisory Board.

Scope

The term knowledge organization system (KOS) is intended to encompass all types of schemes for organizing information and promoting knowledge management. Different families of knowledge organization systems, including thesauri, classification schemes, subject heading systems, and taxonomies are widely recognized and applied in both modern and traditional information systems. Various types of KOS have been increasingly embodied as (Web) services to facilitate resource discovery and retrieval. Different agents, services, and applications need to communicate about KOS data in the form of transferring, exchange, transformation, mediation, migration, and integration. The information about a KOS, including its data model, type, protocol, status, responsible body, available format, affectivity, and other descriptive data are very important to terminology registries, service registries, vocabulary users (machine or human), and retrieval systems. At a minimum level, metadata for KOS resources will describe specific characteristics of a KOS, facilitate the discovery of KOS resources, assist in the evaluation of such resources for a particular application or use, and facilitate sharing, reusing, and collaboration of the KOS resources.

Currently there is no protocol for describing KOS resources. The DCMI/NKOS Task Group targets to develop a Dublin Core Application Profile for KOS resources based on the work the NKOS group* members have already done during the last decade. The application profile will be further tested by professionals and researchers.

Related to this DC Application Profile is a KOS Type vocabulary. It will include various types of KOS, defined based on characteristics such as structure and complexity, the relationships between concepts, and historical function.


Work plan

The 2-year project will have two phases for development and testing/evaluation. The Task Group's goal is to present the draft specification by DC-2010 conference and start the testing from then. The draft specification will include the application profile, the KOS Type Vocabulary, and related best practice guides.

Phase I: Development

  • Set up DCMI-NKOS Working Group, to involve experts and the community. (Ongoing during December 2009 and beyond)
  • Review current research results derived from various projects of the NKOS group members. (Internal report by Mid-January 2010)
  • Develop a functional requirements specification, outlining what kinds of functionality the application profile is intended to support. (Draft by mid-Feb 2010)
  • Develop a simple entity-relationship model on which the application profile can be based. (Same time-frame as above: Draft by mid-Feb 2010)
  • Develop a Dublin Core application profile corresponding to the model. (draft by end of June 2010)
  • Revise and finalize KOS Type vocabulary (draft by the end of June 2010)
  • Online expert review period (one month review in July 2010, for the AP draft and the KOS Type Vocabulary)
  • Revision of the AP and the KOS Type Vocabulary (by the end of September, to be ready for workshop in DC-2010 conference)
  • Report preliminary results and discuss at the NKOS Workshops (U.S. and ECDL) in 2010 (schedule to be decided in 2010)

Phase II: Testing/Evaluation

  • Develop AP Beta and the KOS Type Vocabulary Beta based on DC2010 workshop result (by mid-November 2010)
  • Conduct testing (self- and invited) at extended KOS resources registries and directories (by end-February 2011)
  • Collect examples and develop a set of best practices guidelines for each of the properties in the application profile (draft by the end-April 2011)
  • Online expert and community review of whole specification (AP, Vocabulary, Best Practices) (starting in May, depending on the progress, till end of August 2011)
  • Liaise with the DC Architecture WG to ensure overall compatibility with the DCMI Abstract Model (Ongoing until end September 2011)
  • Release the final Dublin Core Application Profile for KOS Resources (before DC2011 conference)

All work will be undertaken through a working group mailing list, face to face meetings at DC-2010 conference and NKOS workshops, and a working Wiki.

History

  • Task Group constituted: 2009-12-21

(*) NKOS ( http://nkos.slis.kent.edu/) is a community of more than 300 practitioners from more than 10 countries who are interested in the use of knowledge organization systems in networked environments. The group has been organizing workshops on KOS-related topics in the U.S. and Europe since 1998.
