Charter

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. See also Web page.

Developing a Dublin Core Application Profile for KOS Resources

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[1] 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 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.
• Review current research results derived from various projects of the NKOS group members.
• Develop a functional requirements specification, outlining what kinds of functionality the application profile is intended to support.
• Develop a simple entity-relationship model on which the application profile can be based.
• Develop a Dublin Core application profile corresponding to the model.
• Revise and finalize KOS Type vocabulary.
• Online expert review period.
• Revision of the AP and the KOS Type Vocabulary.
• Report preliminary results and discuss at the NKOS Workshops.

Phase II: Testing/Evaluation

• Develop AP Beta and the KOS Type Vocabulary Beta based on DC2010 workshop result
• Conduct testing (self- and invited) at extended KOS resources registries and directories
• Collect examples and develop a set of best practices guidelines for each of the properties in the application profile
• Online expert and community review of whole specification (AP, Vocabulary, Best Practices)
• Liaise with the DC Architecture WG to ensure overall compatibility with the DCMI Abstract Model
• Release the final Dublin Core Application Profile for KOS Resources

All work will be undertaken through a working group mailing list, face to face meetings at DC conferences and NKOS workshops, and a working Wiki. [|search engine optimisation techniques ] [|car finance ]
