Link to properties URIs

I believe that we should, as in the property proposal, set as value the URI of the equivalent property and not an URI of its description. I've already updated the few occurrences of this property like in this diff. Tpt (talk) 07:08, 4 December 2014 (UTC)

Absolutelyǃ The "namespace" URLs (also called semantic URLs, Class/Property URLs) have very special status since RDF statements are made against them. You're not just pointing to a description, but saying "this thing (URL1) has equivalent semantics to that other thing (URL2)", and therefore must be precise about URL2. Use the true namespace of the target ontology.

@Jura1:: Please fix https://www.wikidata.org/wiki/Property:P21#P1628 to http://xmlns.com/foaf/0.1/gender (for some reason I don't have edit rights)

--Vladimir Alexiev (talk) 07:19, 12 February 2015 (UTC)

I don't quite understand the edit on P21. Now it points nowhere. ----- Jura 09:35, 21 February 2015 (UTC)

These URIs are done to return machine readable descriptions of the properties (usually in RDF) often, with a more or less good fallback to HTML description for humans. If you want to know more about it (and the linked data world), there is a very nice book that introduces it). Tpt (talk) 10:25, 24 February 2015 (UTC)

Actually, there's no requirement that RDF property URIs (or [XML] namespace URIs) point to anything; they're nothing but names for concepts, and any description you may find by dereferencing such URIs are just a bonus, spec-wise. —SamB (talk) 04:41, 10 April 2015 (UTC)

Properties with an URL

I suspect that most of the properties with P1630 should also have P1628 set, but most don't. --Nemo 09:19, 4 April 2015 (UTC)

Mapping with OpenStreetMap

Hi @Thadguidry, Federico Leva (BEIC), Pigsonthewing, Gstupp, Tpt: (5 top users of this property),

Is this Special:Diff/564465420 the correct to use this property? (on the formatting and the URL to use on the OSM side ; for the background, I know it's the same concept and values).

Cdlt, VIGNERON (talk) 18:00, 23 September 2017 (UTC)

No, that's what OpenStreetMap tag or key (P1282) is for. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:23, 24 September 2017 (UTC)

Semantics - when should this be used?

I don't understand the semantics of this property. It uses itself to define itself as being an equivalentProperty to owl:equivalentProperty (ie "P1628 P1628 owl:equivalentProperty ."), but this is circular. If it is truly equivalent (i.e. "P1628 owl:equivalentProperty owl:equivalentProperty .") then the current triple "P1628 P1628 skos:exactMatch ." is wrong (since this would entail that skos:exactMatch has domain/range being property). There was some discussion of this in https://www.wikidata.org/wiki/Wikidata:Property_proposal/Archive/27#P1628 but I don't see the resolution being documented as triples about P1628. Based on current usage I am assuming that the intended semantics are actually more like "matches" than logical equivalence. Cmungall (talk) 19:22, 31 March 2018 (UTC)

Question: Why is this not also an instance of "Wikidata property for ontology mapping" ?

Why the "meta" in "Wikidata metaproperty for ontology mapping"? Any reason why it could not also be an instance of Wikidata property for ontology mapping (Q30249126) ? Thadguidry (talk) 14:19, 6 April 2018 (UTC)

BUMP: I have not received a response to this question and thus looking forward to one. --Thadguidry (talk) 14:40, 21 May 2022 (UTC)

query for http or https

this is really annoying. Rotten Tomatoes (Q105584) consistently uses http over https. is there a way not to query properties without having to query for both protocols?

{
  ?item wdt:P1628 <${ namespace.replace(/^https\:/, 'http:') }/${ prop }>.
} UNION {
  ?item wdt:P1628 <${ namespace.replace(/^http\:/, 'https:') }/${ prop }>.
}

Opengraph

I noticed the schema URL for P1476 for opengraph maybe wrong as it currently goes to http://ogp.me/ns#title which gives a error rather than XML

What should the URL's for opengraph namespaces be (such as title in this example) Back ache (talk) 08:32, 22 September 2021 (UTC)
