  • Each class or property in the vocabulary has a URI constructed by appending a term name to the vocabulary URI. For example:http://w3id.org/nkos#alignedWith

Scope

  • This file specifies the set of RDF classes and properties used in the "Networked Knowledge Organization Systems Dublin Core Application Profile (NKOS AP)". The metadata schema can be used to describe knowledge organization systems/services (KOS) resources, such as thesauri, classification schemes, subject heading systems, taxonomies, and ontologies that are developed for organizing information and promoting knowledge management.[1] 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.
  • This Dublin Core Application Profile for describing KOS resources is developed based on the work the Networked Knowledge Organization Systems (NKOS) group "http://nkos.slis.kent.edu/" [5] members have done since 1998.

[1] For the types of KOS resources, consult NKOS-Types vocabulary [6].
