SKOS Core Vocabulary Nikki Rogers Alistair Miles Members of the public-esw-thes@w3.org mailing list. Dave Beckett An RDF vocabulary for describing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', other types of controlled vocabulary, and also concept schemes embedded in glossaries and terminologies. 2006-04-18 The 2006-04-18 '2nd W3C Public Working Draft (Amended)' edition of the SKOS Core Vocabulary, amended to fix an error in the namespace for the 'Resource' class. SKOS Core Vocabulary 2006-04-18 '2nd W3C Public Working Draft (Amended)' Edition 2005-09-29 unstable Labelled collections can be used with collectable semantic relation properties e.g. skos:narrower, where you would like a set of concepts to be displayed under a 'node label' in the hierarchy. Alistair Miles 2005-09-29 The statement about this resource, involving the skos:subjectIndicator predicate, was removed. Collection 2004-10-20 A meaningful collection of concepts. Alistair Miles 2004-12-17 The word 'meaningful' added to the definition. Small change to the comment to make it clearer. 2004-10-20 unstable Ordered collections can be used with collectable semantic relation properties, where you would like a set of concepts to be displayed in a specific order, and optionally under a 'node label'. 2005-09-29 Alistair Miles 2004-12-17 The text 'where both the grouping and the ordering are meaningful' added to the definition. Ordered Collection An ordered collection of concepts, where both the grouping and the ordering are meaningful. Alistair Miles 2005-09-29 The statement about this resource, involving the skos:subjectIndicator predicate, was removed. The following rule applies for this property: [(?x ?p ?c) (?c skos:member ?y) (?p rdf:type skos:CollectableProperty) implies (?x ?p ?y)] 2004-10-20 A property which can be used with a skos:Collection. 2005-09-29 unstable Alistair Miles 2005-09-29 The statement about this resource, involving the skos:subjectIndicator predicate, was removed. Collectable Property Alistair Miles 2005-02-09 Definition modified from 'A description of a set of concepts, which may include a description of relationships between those concepts'. Comment added 'Thesauri, classification schemes, subject heading lists, taxonomies, terminologies, glossaries and other types of controlled vocabulary are all examples of concept schemes'. Change to bring in line with SKOS Core Guide and definition at Willpower Glossary. Alistair Miles 2004-10-20 Added a definition; added an example; deprecated old comment; added new comment; added xml:lang value to label. 2004-03-26 Alistair Miles 2005-09-29 The statement about this resource, involving the skos:subjectIndicator predicate, was removed. A set of concepts, optionally including statements about semantic relationships between those concepts. Concept Scheme testing Alistair Miles 2005-10-14 Comment changed to be clear about the fact that glossaries and terminologies are not types of controlled vocabulary. 2005-10-14 Thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', and other types of controlled vocabulary are all examples of concept schemes. Concept schemes are also embedded in glossaries and terminologies. Alistair Miles 2004-12-17 Reworked the definition, in line with new guide. Concept scheme now defined as 'a *description* of a set of concepts, which may include a description of relationships between those concepts'. This change made to make explicit the fact that semantic relationships between concepts may be part of a concept scheme. Also expresses modelling concept scheme as an information resource (hence the 'description' word added). A concept scheme may be defined to include concepts from different sources. Concept Alistair Miles 2004-12-17 Removed the comment about inferring the meaning of a resource of type skos:Concept, because it was misleading (move to intentional model, where properties of a concept *explain* the meaning of the concept, but do not determine it. This allows for clearer modelling of concepts in multiple schemes). An abstract idea or notion; a unit of thought.
