Hi all,

Can we agree that the version of EARL is primarily determined by its 
Schema document? The three other specs (HTTP-in-RDF, Content-in-RDF and 
Pointers-in-RDF) are designed to be supplemental, which is alone of the 
reasons why they are WG Notes. IMHO, updating HTTP-in-RDF will usually 
not change the EARL fundamentals, and should therefore not require the 
version number to change. However, changes to the Schema document will 
typically have more direct consequences on EARL as a whole.

Having said that, we still need to address versioning of the supporting 
documents around EARL 1.0 Schema. We could:

# add a version number - for example "HTTP Vocabulary in RDF 3.2", this 
may sometimes become more ambiguous.

# use revision numbers - for example "HTTP Vocabulary in RDF (Third 
Edition)", this is useful if the changes are primarily refinements.

# use publication date - for example "HTTP Vocabulary in RDF, 9 January 
2010", this does not need any changes but is not as apparent.

Personally, I'd favor the second approach for at least HTTP-in-RDF and 
Content-in-RDF since we do not expect any major changes to these (maybe 
just some new headers or other refinement but nothing substantial).

NOTE: the support document for WCAG 2.0 do not have version numbers. It 
is currently expected that date references will be used to disambiguate 
between versions of the "Techniques" or "Understanding" documents.
