RE: [cmis] CMIS Atom WG notes

[Davis_Cornelia@emc.com]

I’ll just add a few comments on item #2:

 

What we decided was that since the schema are non-normative, and thus, the onus is on getting the details of the cmis extensions to atom adequately described in the prose, that the extra effort required to craft and maintain a set of xsds that support both the expression of generic Atom representations and CMIS extensions to Atom was not warranted.  The purpose of the schema on the REST side is for information (I think most of us will read schema for clarification on some point – even if the schema is non-normative and therefore _possibly_ incorrect) and because the xsds can also be used with tooling, to do things like generate helper functions and the like.  A more complex xsd can be crafted (such as what I posted last evening) but it is unclear that the extra effort brought much to CMIS – so we will only include the generic Atom xsd.  This does not preclude someone from posting more sophisticated schema files that describe the cmis extensions in more detail but this would not be included as a part of the spec, rather it could be posted by anyone as a utility that helps with cmis-based work.

 

BTW, I think that formalizing a way for Atom extensions to be specified, specing Atom profiles if you will, is a good potential topic for a possible Atom WG (as being discussed on the Atom mailing lists).

Subject: [cmis] CMIS Atom WG notes

 

Attendees:

1. Ryan McVeigh
2. Cornelia Davis
3. Julian Reschke
4. Nikunj Mehta

Discussion:
1. Versioning - Julian will publish I-D. Two items not in consensus
a. working-copy
b. latest-version vs. current-version (retrieval-based semantics) vs. base-version (check out-based semantics)
2. XSD - Leverage Generic XSD
3. Hierarchy - TBD. Nikunj will work on incorporating signaling (e.g., this link relation points to a resource containing inline markup).

The WG will reconvene on Fri @ 8AM PST.
