ISSUE-35: Consider relationship between LinkTypes in RDFa and the IETF LinkType registry

IETF LinkType registry

Consider relationship between LinkTypes in RDFa and the IETF LinkType registry

State:
CLOSED
Product:
RDFa 1.1 Core
Raised by:
Manu Sporny
Opened on:
2010-07-14
Description:
The IETF is preparing to setup a LinkType registry. Many of the LinkTypes come from W3C specs. There are a few LinkTypes like 'license' and 'service' that come from other IETF specs.

We should discuss the positive and negative effects of attempting to merge W3C and IETF LinkTypes specified in this registry. Do we want to migrate all LinkTypes in the registry into the XHTML+RDFa and HTML+RDFa specs?

Also note that comparisons are done in a case-insensitive fashion in that spec. This would mean an additional set of LinkTypes that should be generated based on a case-insensitive match. For example, rel="SERvice" should generate a triple if we merge IETF LinkTypes into the XHTML+RDFa spec.

Related notes:

RESOLVED to not have RDFa 1.1 depend on the IETF LinkTypes registry at the moment. Merging the link type registry should be considered on a RDFa implementation language-by-language basis. If the IETF LinkTypes registry is accepted as the official LinkTypes registry for the Web, the terms should be placed into the corresponding default RDFa Profile document for the language:

http://www.w3.org/2010/02/rdfa/meetings/2010-09-30#resolution_2

That is to say, the hard-coded term mappings in RDFa 1.0 for a language have been de-coupled from the main specification body. The RDFa language term mappings are now expressed via an RDFa 1.1 Profile document.
