Add link classification by site type in RDF
Closed, ResolvedPublic
Actions

Description

Right now links in RDF are represented like this:

<http://en.wikipedia.org/wiki/Duck> a schema:Article ;
    schema:about wd:Q3 ;
    schema:inLanguage "en" ;
    wikibase:badge wd:Q5 .

Which has one glaring omission: it is hard to distinguish between links to sites in the same language, such as English Wikipedia and English Wikisource. It would be nice to have some way to make it easier.

Options:

  • schema:isPartOf <http://en.wikipedia.org/>
  • schema:isPartOf wd:Q1234, where wd:Q1234 is an entity for English wikipedia
  • wikibase:wikiType wikibase:Wikipedia
  • wikibase:wikiType wd:Q1234, where wd:Q1234 is an entity for English wikipedia

Other ideas?

<http://en.wikipedia.org/wiki/Duck> schema:isPartOf <http://en.wikipedia.org/>
<http://en.wikipedia.org/wiki/Duck> wikibase:wikiGroup "wikipedia"

I'd prefer to attach the group to the site, not the page:

<http://en.wikipedia.org/wiki/Duck> schema:isPartOf <http://en.wikipedia.org/>
<http://en.wikipedia.org/> wikibase:wikiGroup "wikipedia"

Also, we should think about whether http://en.wikipedia.org/ or http://en.wikipedia.org/wiki/ is semantically correct. I'm leaning towards the latter.

Smalyshev added a comment.EditedMar 14 2016, 4:48 PM

/wiki/ is an implementation detail, not really a part of what identifies the site, and also not what we see e.g. in https://www.wikidata.org/wiki/Q328 in "official website" property.

As for <http://en.wikipedia.org/> wikibase:wikiGroup "wikipedia" I see you point, but then it looks wasteful to repeat the same triple over and over... Maybe we should deduplicate it then?

daniel added a comment.EditedMar 14 2016, 6:07 PM

@Smalyshev Indeed, the idea was to output <http://en.wikipedia.org/> wikibase:wikiGroup "wikipedia" only once, not for every sitelink.
