Subject Re: Working on CMIS
Date Fri, 20 Feb 2009 08:54:56 GMT
Hi all,

Yes the architecture I want is the one also outlined in David's  
slides. I propose that the code be structured like this:

  Interfaces based on the CMIS spec, but made Java-ish
    Client using AtomPub
    Client using SOAP
    Server using AtomPub
    Server using SOAP
  Common utility classes used by client/server parts, for instance:
    - a simple implementation for Document, Folder, etc.
    - a parser and AST for SQL queries
  Some upcoming, *unofficial* tck for CMIS, basically lots of unit tests
  The implementation of cmis-api on top of a JCR repository
cmis-webapp-atompub (or cmis-sample-browser ?)
  The sample webapp connecting to a remote CMIS repository using AtomPub

The code existing in the sandbox would be moved to fit in the above  
hierarchy, nothing is lost.

I've started working on the refactoring in a Mercurial repository here  
at Nuxeo (just the cmis-api for starters), and I'll provide patches as  
soon as all the tests pass. I'll give you a URL for the repository  
when it's set up today.
The refactoring will basically have to define (a first draft of) the  
CMIS Java API, and change the clients and server to use them as  
intermediate datastructures.

How does that sound?
I'd like to use org.apache.cmis as the package base for all the cmis-*  
bundles, does anyone foresee a problem with that?
