Indeed.

Manu, I'm not sure whether the Wiki is supposed to be open for 
discussion, or whether you simply collect discussion topics over there.

So here's one more comment on 
<http://rdfa.info/wiki/Rdfa-in-html-issues#Bogus_reserved_words>:

"From Philip Taylor's RDFa in HTML tests:

<link rel="next bogus prev" href="http://example.org/test.css" />

Answer: The expected is wrong, the following triple should not be generated:

<> <http://www.w3.org/1999/xhtml/vocab#bogus> 
<http://example.org/test.css> .

There is a conformance requirement to not generate triples for 
non-reserved words. Test Case #86 in the RDFa Test Harness checks this 
conformance requirement."

The issue here is that there doesn't seem to be agreement outside the 
XHTML2 WG that that WG indeed is responsible for maintaining the list of 
reserved keywords. Pretending that what you decided is good for RDFa in 
XHTML doesn't necessarily mean it's going to work everywhere else.

Right now there are the following registries and registry documents for 
link relations in general (unless I missed one):

- HTML4 (<http://www.w3.org/TR/html4/types.html#type-links>)
- HTML5 Working Draft 
(<http://dev.w3.org/html5/spec/Overview.html#linkTypes>)
- XHTML2 Vocabulary (formal status???) 
(<http://www.w3.org/1999/xhtml/vocab/>)
- WhatWG Wiki (<http://wiki.whatwg.org/wiki/RelExtensions>)
- Atom Link Relations (IETF Proposed Standard) 
(<http://greenbytes.de/tech/webdav/rfc4287.html#rfc.section.7.1> and 
<http://www.iana.org/assignments/link-relations/link-relations.xhtml>
- Web Linking (IETF Internet Draft) 
(<http://greenbytes.de/tech/webdav/draft-nottingham-http-link-header-05.html>), 
proposing a new IANA registry, merging Atom and HTML relation names

Of these, only HTML5, Atom, and Web Linking seem to propose a way how to 
register relations in the future (note that I strongly disagree with the 
HTML5 proposal to use a Wiki for that, though).

So, what's the registration procedure for 
<http://www.w3.org/1999/xhtml/vocab/> -- and who's going to maintain it 
once the WG ceases to exist?

What we need is a format-neutral registry (I want to be able to express 
link relations from non *HTML documents as well), and a registry that 
works in practice.


BR, Julian
