Add preferred prefixName to registry? #17

Closed sesuncedu closed 9 years ago

sesuncedu commented 9 years ago

This would be useful for prefix aware output forms. Have to parse the IRI anyway, so might as well take advantage of it.

No other serialization format keeps prefixes when parsing, as prefixes are not an RDF concept, but that of a serialization. As microdata has no such concept, I'm not sure that this makes any sense. Prefix information is available in other places, such as the RDFa Initial Context, but I don't see the value in adding that to the registry.

I agree. The conversion aims at an abstract RDF graph, not a particular serialization.

Section 5 on Web processors is where the concrete spec is used. On Dec 15, 2014 3:14 AM, "Ivan Herman" notifications@github.com wrote:

I have the impression that there is a confusion with the terminology. The document uses the term URI prefix (see http://www.w3.org/TR/2014/NOTE-microdata-rdf-20141216/#dfn-uri-prefix) but that is not the prefix in the sense of a CURIE or Turtle. I guess there is a conflation with the terminology used in the microdata spec, but we have to live with this I am afraid.

I mark this issue as closed for now.
