Adding links to a concept

[koenedaele]

Sometimes, it's nice to add links from a concept to other webpages related to the concept. Eg. from https://id.erfgoed.net/thesauri/erfgoedtypes/32 we would like to link to https://id.erfgoed.net/themas/35, a theme in the inventory that has similar but not identical information. Suggesting that people might want to look at that other page as well. So, we're looking for a property that allows a general link with some other part of the web (not necessarily that it exists as RDF itself).

Possible solutions in RDF:

• skos: exactMatch, closeMatch, broadMatch, narrowMatch, relatedMatch
• rdfs: seeAlso
• schema.org: url

We're currently using skos:matches for matches between concepts and I don't want to make any other statements about the url's we're linking to, so that's out. Which leaves rdfs:seeAlso or schema:url. I have a slight preference for rdfs:seeAlso since that fits what we're trying to do nicely.
