Hi Joachim, The site looks good, I'm looking forward to a full release :) I checked out the triples, looks very reasonable. I had one thought about a possible option for representing the labels, I'm not necessarily saying it's better, but just raising it as an option... Instead of ... <skos:Concept rdf:about="http://www.zbw.eu/beta/stw/thsys/090858891"> <skos:prefLabel xml:lang="en">P.01.01 Crop production commodities</skos:prefLabel> <skos:prefLabel xml:lang="de">P.01.01 Pflanzenbauprodukte</skos:prefLabel> </skos:Concept> ...you could do something like... <skos:Concept rdf:about="http://www.zbw.eu/beta/stw/thsys/090858891"> <skos:prefLabel xml:lang="en">Crop production commodities</skos:prefLabel> <skos:prefLabel xml:lang="de">Pflanzenbauprodukte</skos:prefLabel> <skos:notation rdf:datatype="http://www.zbw.eu/beta/stw/notation">P.01.01</skos:notation> </skos:Concept> Cheers, Alistair On Fri, Feb 06, 2009 at 01:15:48PM +0100, Neubert Joachim wrote: > > Hi Dan, > > you asked about using rev= instead of rel= in RDFa notation. That's possible, of cause, and since I have a tech preview of the application online now (eg. http://www.zbw.eu/beta/stw/descriptor/14066-0), I built it experimentally with a custom property, stw:indexes (as a subproperty of rdfs:seeAlso) and the embedded RDFa relations > > rel="stw:indexes rdfs:seeAlso" > rev="dcterms:subject" > > to link from the concept to the search result set of the library system. > > Browsers behave differently on this (Marbles and Tabulator display an "is subject of" line, Zitgist does not), so tool support may or may not be given. > > However, what seems more important to me: As Antoine pointed out earlier in this conversation, any subject/isSubjectOf relation is highly asymetric. Semantic web browsers are awfully slow already. They would be much more so if they had to display all reverse relations to "dc:subject" in a big library holdings (let alone from the web in total). I'm quite sure that the display of inverse relations will be optional in future versions of such tools. > > Therefore I think it makes sense to use a property which expresses the desired relation directly. > > Cheers, Joachim > > > -----Ursprüngliche Nachricht----- > > Von: Dan Brickley [mailto:danbri@danbri.org] > > Gesendet: Donnerstag, 5.
