Both DBpedia and Freebase support the concept of redirection. DBpedia has the I think both of these predicates mean that "the topic formerly known as ?subject is now known as ?object", it's like the message you get on the phone when a phone number has changed. Is there some ?standardProperty such that ? It seems that the redirection concept is related to the 300-family status codes in HTTP, which specify 4 types of redirect with specific semantics for the client. It seems also that redirection could be made more specific as to the reason for the redirection -- I could see either having N different redirection predicates or otherwise reifying the redirection event. Is there anything out there, simple or complex, to represent redirection that isn't tied to a particular product? |

Might be a little heavy-weight, but the HTTP vocabulary would be one avenue for (verbose) redirect modelling. 1
This is good for modeling HTTP; perhaps it would model Freebase in some way since Freebase will do an http redirect if you visit an obsolete mid on the HTML site. On the other hand, Wikipedia doesn't do an http redirect when a concept is 'redirected', it just displays the target page on the original URL... For derefenceable resources, then you should be able to use the HTTP vocabulary, otherwise I would use something else. "Redirects" in DBpedia are derefenceable but don't use http redirects, instead DBpedia publishes a document with the dbpontology:wikiPageRedirect. Actually, I suspect it might make sense to use it in part for any HTTP resource. For something lighter weight, why not use rdfs:seeAlso , although this is probably being used already for Wikipedia's 'see also' and is better used in that context. |
