SV: [Dbpedia-discussion] [ANN] Add your links to DBpedia workflow version 0.1 (this is also an RFC)

I'm not sure I get the usefulness of skos:Concept in DBPedia. To get the list of countries you can do

SELECT ?s WHERE {?s a dbo:Country}

If you do a SELECT ?s WHERE {?s a skos:Concept} you would get whatever someone decided is a skos:Concept. In principle you could get all entities in the database. To make it useful you'd have to make skos:Collections of all the classes (i.e. dbo:Country) and then use skos:member to connect it all.

The skos:*Match predicates don't have domain/range properties, so they can be used outside SKOS vocabularies without side-effects.

I also think this quite important.

What I would really like to see is certain conceptual things in dbpedia
is typed with skos:Concept. That gives me some assurance and encourages
me (and probably others) to use skos:*Match where appropriate instead of
slapping owl:sameAs.

For instance, resources that are of type dbo:Country, can we have
skos:Concept for these for starters? :)
