Hi,
Here is a short update of what we have covered today in the
Chemistry face-to-face meeting.
* Presentation of OpenCMIS [1] and Chemistry [2] concepts and ideas.
Getting everyone on the same page. No news, just a summary of what
has been described on the Chemistry Wiki and on the mailing list.
* Moving forward with Florents merge proposal.
We use Florents merge proposal [3] as the basis for the next
discussions.
* Discussion about the low-level client API and server SPI.
Chemistry has the same set of interfaces for both, the client API
and server SPI. That allows to set up a client in the same JVM as
the repository without a network connection. (See [2] for details.)
Unfortunately, the current approach cannot provide a fully complaint
AtomPub implementation.
OpenCMIS has separate interfaces for the client and the server. The
client API is modeled after the CMIS specification and independent
of the binding. The server SPI takes binding details into account
which is necessary to provide complaint AtomPub and Web Services
interfaces.
We all agree that a local loopback would be useful. The discussion
on how to achieve this hasn't been finished. There are two basic
proposals:
1. Keep the different client API and server SPI and build a thin
layer that does the translation.
2. Rework the API and SPI that they eventually become one. There is
probably no way do this without introducing operations and/or
parameters that don't make sense for users of the client API.
For what is worth, my +0 on trying to have a loopback interface as
long as it does not complicate / confuse CMIS client usage: IMHO
fostering and simplifying client repository access is definitely the
biggest use case we should cover.
Keep up the good work guys,
Gab
We will dive deeper into this discussion tomorrow.
