Embedding Programmes Ontology metadata in web pages
Just a random thought regarding the Programmes Ontology.
I wonder if there’s value in embedding PO metadata in HTML pages showing videos (rather than simply linking to an RDF source via <link rel="alternate" …>.
We already have a way to embed Dublin Core metadata:
<link rel="schema.DCTERMS" href="http://purl.org/dc/terms/">
<meta name="DCTERMS.created" content="2009-04-03T13:28:09Z">I wonder if there’s value in embedding PO metadata along the same lines. Using b00r60gp as an example picked pretty much at random:
<head profile="http://dublincore.org/documents/2008/08/04/dc-html/">
<title>BBC - BBC Radio 4 Programmes - Am I Normal?, Series 7, Ageing</title>
<link rel="alternate" type="application/rdf+xml" href="/programmes/b00r60gp.rdf">
<link rel="alternate" type="application/json" href="/programmes/b00r60gp.json">

What say you, Yves? :)
(Of course, all of those <link>s could be inline anchors instead, if the markup were amenable to it—pretty sure the current /programmes pages mostly are).
