Larry,

The TAG took on metaDataInIRI-31 [1] at its meeting in 2nd December [2] to
uphold the principle that encoding metaDataInURI is not a good idea (and I
have subsequently picked up the action to draft a short finding). 

From [2]:

  TB: Notion of encoding metadata in a URI is broken. Versioning has
application-specific semantics.
  ...
  CL: If we universally thing this is a bad thing to do, we should say so
loudly.
  SW Proposed: Accept medataInURI-NNN? 
  IJ: Could be short if universal response is "no".
  Resolved: Accept issue matadataInURI-NNN with note that TAG thinks the
answer is "no" 
            and will explain what to do instead.

Although, Ori's message [3] covered wider ground, embedded within were
notions of embedding versioning info in URI. Mark Baker caution against it
[4]. The TAG felt it would be useful to generate a short finding
discouraging the embedding of meta-data in URI. The 'stinger' (for me) is
the commitment in the last 6 words of the resolution, which I admit I had
lost sight of.

Certainly in accepting this issue it was not the TAG's intent to "go off
inventing new mechansims" and to fulfill the commitment of the last 6 words
of the resolution I will have a look at WebDAV to "evaluate where WebDAV
fits into the Web architecture".

Regards

Stuart
