Every Wikipedia, Wikivoyage, Wikisource and Commons "article" has an indicator that there is a Wikidata item associated with it already. It is part of the tools in the sidebar.

Or are you talking about web pages external to the WMF?

In particular we had Wikipedia in mind. http://xmlns.com/foaf/spec/#term_primaryTopic http://xmlns.com/foaf/spec/#term_isPrimaryTopicOf (Both of these share a classic Semantic Web pickyness about distinguishing things from pages about those things). Much more recently at schema.org we've added a new property/relationship called http://schema.org/sameAs It relates an entity to a reference page (e.g. wikipedia) that can be used as a kind of proxy identifier for the real world thing that it describes. Not to be confused with owl:sameAs which is for saying "here are two ways of identifying the exact same real world entity". None of these are a perfect fit for a relationship between a random Web page and a reference page. But maybe close enough? Both FOAF and schema.org are essentially dictionaries of hopefully-useful terms, so you can use them in HTML head, or body, according to taste, policy, tooling etc. And you can choose a syntax (microdata, rdfa, json-ld etc.). I'd recommend using the new schema.org 'sameAs', .e.g. in rdfa lite, <link href="https://en.wikipedia.org/wiki/Buckingham_Palace" property="http://schema.org/sameAs" /> This technically says "the thing we're describing in the current element is Buckingham_Palace. If you want to be more explicit and say "this Web page is about a real world Place and that place is Buckingham_Palace ... you can do this too with a bit more nesting; the HTML body might be a better place for it.

How about using RDFa and foaf:primaryTopic like in this example https://en.wikipedia.org/wiki/RDFa#XHTML.2BRDFa_1.0_example 2014-02-26 20:18 GMT+02:00 Paul Houle &lt;ontology2(a)gmail.com&gt;om>: > Isn't there some way to do this with schema.org?
