How can i parse a RDFa fragment?

[VicMan]

Hi all,

Can someone show me how to parse a rdfa fragment with rdfquery?

I have tried this:

<div id="#content">
<span about="http://purl.org/ontology/mo/Vic" id="890651"
typeof="http://purl.org/ontology/mo/MusicArtist">VicMan<span
property="http://xmlns.com/foaf/0.1/age" content="18" datatype="http://
www.w3.org/2000/01/rdf-schema#Literal" id="303062">18 years old</
span></span>
</div>

$('#content').rdf().where('?a ?b ?c').length

=> 0

Thanks.

It seems to work when the rdfa attributes are CURIEs

<span about="mo:TestArtist" typeof="mo:MusicArtist">This is a text
about a <span property="rdfs:label">Test Artist</span></span>

$('#content').rdf().databank.size()
=> 2

But when I use URIs they are ignored by rdfQuery:

<span about="http://purl.org/ontology/mo/TestArtist" typeof="http://
purl.org/ontology/mo/MusicArtist">This is a text about a
<span property="http://www.w3.org/2000/01/rdf-schema#label">Test
Artist</span></span>

$('#content').rdf().databank.size()
=> 0

Does anyone know what's wrong?

Well, see [1] for the details - rdfQuery just happens to follow the spec ;)

Cheers,
