Hey @edsu –
just read, watched & enjoyed https://inkdroid.org/2015/05/20/skos-and-wikidata/ #wikidata
Personally I am also using #SKOS cause of the https://skohub.io approach @acka47
What I wonder about:
Can't we say in SKOS:
- This wikidata property wd:P… is the same than this skos:Concept
or
- This skos:Concept is described by wikidata entity wd:Q…
Basically my software maps Linked Data and other SKOS in this way but how about wikidata or even non-LD-APIs ?
Does anybody know, what is the best way to describe such ?
The concrete example is that we have published the first part of the Vocabulary at the page https://redaktor.github.io/vocab/
following the https://skohub.io approach.
What I would now like to express in the turtle files in huge https://github.com/redaktor/vocab/blob/main/Vocab.ttl is e.g.
for a movie Director:
concept 012011
can appear as wikidata property
P57
or
concept 012011
is described by wikidata entity
Q3455803
@sl007 @acka47 ok, I understand now, and I don't know the answer. I think in semweb land that pushes into reification, which was never something I really understood very well.
Is there a reason why you wouldn't want to use one of the skos:mappingRelation to link to https://www.wikidata.org/wiki/Q3455803 instead?
@sl007 @acka47 would it be bad to infer that Wikidata is a concept scheme? It looks like the Library of Congress doesn't think so, e.g.
https://id.loc.gov/authorities/subjects/sh85088067.skos.json
I haven't kept track of how other people are linking to Wikidata from SKOS. It seems like if you did you'd want to link to something that's a resource and not a property?
So. This is interesting.
Well, of course I had looked in LOC :)
But I expected it to be directly in the SKOS concepts like in our example
https://id.loc.gov/vocabulary/relators/drt.json is this https://id.loc.gov/vocabulary/relators/drt.json
@sl007 @edsu For linking skos:Concepts to things, there is foaf:focus. We use it for example in https://nwbib.de/spatial
@acka47 @sl007 yes, I'm remembering that now -- I seem to remember that getting some traction ... https://journal.code4lib.org/articles/15875 -- linking to the property doesn't seem to make much sense to me though, but I've been out of the game for a while.
@edsu @sl007 Yes, linking SKOS concepts to properties seems incorrect but I understand why Sebastian would like to add a link to the property. I don't know of a property made for this. Of course you can always add it to the skos:definition for humans to see the relation. Or you create your own property to state this relation...
@sl007 @edsu @acka47 did you see the "exact match"? https://www.wikidata.org/wiki/Q96479983
Plz also check "equivalent property": https://www.wikidata.org/wiki/Property:P2888#P1628
