Mainly because querying such data becomes complex since the language is not
visible from an RDF point of view. I would have to filter based on the
contents of that typed literal instead of being able to simply filter by the
language tag associated with that literal.

 

 

Cheers,

Markus

Markus,

if you want language-tagged HTML literal,
why not use the @lang attribute at the root of that HTML literal instead?

I'm sure you already discussed this but unfortunately I wasn't able to find
anything relevant. Was it considered that also literals with datatypes other
than rdf:langString can be language-tagged? I'm specifically thinking of
rdf:html for example..


Thanks,
Markus
