Hi Manu,

Cheers for the reply - all agreed of course, and clarifying the last point:

nope, the primary difference is that store.filter returns a store for 
working with RDF - but I'm putting forward a method which would allow 
you to filter the document by triple and get back the elements - thus 
addressing the primary thing we're discussing.

I'd certainly like to see it on the document. The filter methods work 
perfectly on the store object to get back triples - why not add matching 
methods to the document to get back elements? to me it seems it would 
cover all the use-cases we've all mentioned.

document.getElementsByFilter("http://www.ivan-herman.net/foaf#me", 
"foaf:name" , null ); // element holding ivan's name

document.getElementsByFilter( null, "foaf:name" , null ); // everybodies 
name(s).

Basically just allows us to use RDFa s/p/o as DOM Element selectors.

Not sure if I'm explaining this correctly

Best,

Nathan
