Issues tracker: ISSUE-26, ISSUE-27

The first decision point here is, do we move all support for label relations out of the SKOS vocabulary and into XL?

The second decision point is, do we publish XL as part of the SKOS Recommendation? If so, is it an appendix to the SKOS Reference, or is it a separate document?

We should continue discussion here *only if* we have previously agreed that XL is part of the SKOS Recommendation. Otherwise, we should move on to other issues in scope, and postpone detailed discussion of XL.

If XL is to be part of the recommendation, then:

• How do we make it clear that we don't expect all SKOS implementations to support XL, that it is an optional extension?

• What is the XL namespace? http://www.w3.org/2008/04/skos/xl# ?

• How does the XL namespace dereference?
• Any issues with the XL vocabulary and data model?

Dependencies:

• None
