ISSUE-185: Last Call Comment: Order in Classification Systems http://www.w3.org/2006/07/SWD/track/issues/185 Raised by: Sean Bechhofer On product: All Raised by Michael Panzer [1]: 5. Order in Classification Systems ---------------------------------- Order in a classification is important, indeed critical. Order is evident in the juxtaposition of classes, the sequence of main classes, and the sequence of co-ordinates in a class. Broader and narrower relationships alone cannot represent order. So, maybe parallel encoding is necessary to make sure that the system a classification scheme tries to present is reflected when using SKOS. To some degree, when order is connected to hierarchy, this can be reflected by extensions to SKOS. The DDC for example has two parallel hierarchies, one expressed by length of notation, the other by structure (notes, etc.). This is handled at the moment by extending skos:narrower. skosclass:narrowerStructural rdfs:subPropertyOf skos:narrower . skosclass:broaderStructural rdfs:subPropertyOf skos:broader ; owl:inverseOf skosclass:narrowerStructural .
