Hi Ole,

Would you be adverse to moving the DAS effort over to Tuscany now where it probably belongs?
I'm fine with you hosting it here if you don't have commit access there however I'd like to start
answers your questions on the user@ mailing list without cluttering the dev list with DAS specific
information.  We can simply confront LDAP related issues on both the dev and user list this way.

Either this or perhaps another ML might be in order if we decide to host a OL (Object-LDAP)
mapping project here.

Hi Weijian,

In case you are still interested,
I'll be publishing a new revision
of the DAS LDAP Design Guide in a few days.

This is written as a cook book for how
to write the DAS, so it should be fairly straight
forward to follow.

Also - Apache Tuscany is very supportive
of this approach (We've had many discussions already)
and the project will
likely be moved into Tuscany as soon
as the initial implementation is complete.

I could have a working implementation
right now that reads and writes data graphs,
but there are a few bugs in the ADS
Dynamic Schema capabilities that need to be cleared
first.  As soon as that's done I'll commit to
having an implementation that reads and writes SDO DataGraphs
within 10 days.

Note that SDO DataGraphs are really XSD Instances
and SDO was designed to use XML Schema for Typing.

- Ole
