ISSUE-84: ConstructionOfSystematicDisplaysFromGroupings http://www.w3.org/2006/07/SWD/track/issues/84 Raised by: Antoine Isaac On product: All >From [1]: > I propose the following section of the SKOS Semantics wiki draft as resolution of ISSUE-33 "Grouping Constructs" [2]: > > http://www.w3.org/2006/07/SWD/wiki/SKOS/Semantics/Grouping?action=recall&rev=2> > > This section implements the "Minimal Fix" proposal [2], with a few additional > axiomatic triples to make explicit the OWL typing of properties and the > disjointness of skos:Collection and skos:ConceptScheme. > > Note that this section does not address the issue of constructing a systematic > hierarchical display, but delegates this responsibility to the SKOS Primer. > Note also that the SKOS Primer section on grouping constructs is yet to be >done, and that in particular I have not met Antoine's concerns below regarding > nested collections. > > However, I suggest we accept this resolution for now (because it does fix the > actual issue), and raise a new issue regarding the representation and > construction of systematic hierarchical displays. (Antoine's comment on nested collections are at [3]) Now from [4] (no need to thank me Alistair ;-p) > However, in the absence of any presentational information, there could be a > default method of constructing a systematic display. To handle SKOS grouping > constructs, this would require an algorithm which is *fairly* sophisticated - > certainly not straightforward to a novice hacker. The onus is on me to provide > a reference implementation :) This was reflected in [5]: >(Statement 2) The SWDWG MAY publish an algorithm to generate a default > thesaurus systematic display from an RDF graph using the SKOS vocabulary. > However, applications are not required to use the algorithm, and MAY use any > means to convey information required to construct a thesaurus systematic >display. The current Primer [6] in its section on Collections of Concepts (4.1) does not propose anything: > A systematic (hierarchical) display can then be generated including the > concept grouping "milk by source animal", as presented in the example >introducing this sub-section. The skos:broader hierarchy and the collection >membership information can be used for this, but the process still requires a >dedicated algorithm, the implementation of which is left to specific > applications. Shall we change this?
