ISSUE-182: Last Call Comment: Index Terms http://www.w3.org/2006/07/SWD/track/issues/182 Raised by: Sean Bechhofer On product: SKOS Raised by Michael Panzer [1]: 2. Index terms -------------- An important part of many classification systems is an index, in the case of the DDC its "Relative Index". Index terms associated with a given class generally reflect several of the topics falling within the scope of that class. There is no easy way of modeling this relationship in SKOS: Class/Concept: 616 Diseases Index terms: Clinical medicine Diseases--humans--medicine Illness--medicine Internal medicine Physical illness--medicine Sickness--medicine Currently, a possible workaround is to construct the complete Relative Index as a separate skos:ConceptScheme and relate the concepts in these two independent schemes by using mapping relations: skosclass:hasIndexTerm rdfs:subPropertyOf skos:closeMatch . skosclass:isIndexTermOf rdfs:subPropertyOf skos:closeMatch ; owl:inverseOf skosclass:hasIndexTerm . <class/616> a skos:Concept ; skosclass:hasIndexTerm <index/Clinical%20medicine> ; skos:inScheme <classification> . <index/Clinical%20medicine> a skos:Concept ; skosclass:isIndexTermOf <class/616> ; skos:inScheme <index> . This seems to be a satisfactory best-practice solution in this case, but it has broader implications as index terms are just one instance of Class-Topic Relations [1] http://lists.w3.org/Archives/Public/public-swd-wg/2008Oct/0061.html
