Thanks Alistair, thats the next question i wanted to ask. We were using owl:sameAs and rdfs:seeAlso as an alternative but are changing that to skos:mappingRelations. And i also agree with Andrew that the Sementic Web will survive but being a bit of a pedant too i'd like to have some confidence too. But maybe Linked Data is all about faith. I also found some discussion regarding the use of owl:sameAs: http://www.semanticoverflow.com/questions/1095/alternatives-to-owlsameas-for-linked-data And finally skos:me would definitely like to have a skos:it? t-shirt:) Cheers hel. > Hi, this is an interesting topic that I have some interest in myself, one comment inline below > > Alistair Miles wrote: >> Hi Helmut >> >> On Mon, Jul 12, 2010 at 09:18:29PM +0200, Helmut Nagy wrote: >> >>> Hi, >>> >>> e.g i got an Concept "Vienna" and i want to make the following mapping: >>> >>> "Vienna" skos:exactMatch http://dbpedia.org/resource/Vienna >>> >> >> Possibly a reasonable thing to do.

Unfortunately this means I rarely use matching relations to anything other than skos resources that I have created myself ;-). In the real world Im not sure this makes any difference, and the Semantic Web will probably survive either way, but I think it gives other people more confidence in your vocabulary modelling if its clear some care has been taken. > > DBPedia asserts no skos relations for any resource I have seen (which is not necessarily a bad thing, and I havent checked everything), and so in the absence of anything more specific, I just link from my concepts to dbpedia with rdfs:seeAlso, which "is used to indicate a resource that might provide additional information about the subject resource", so for example, its rdfs:labels or rdfs:comments might be useful to a semantic web application, but do not expect any directly relevant skos relationships that it could do skos things with. > > Cheers, > Andrew >> >>> skos:it? t-shirts? :) >>> >> >> Sorry, Danbri and I had a discussion a while back about ideas for a new inverse >> property pair in SKOS that would be used for linking from SKOS concepts to >> "real things" like people, mountain ranges, etc., and back again.
