Hi Thad,
Can you post your questions to the forum next time:
http://forum.andromda.org?
About the OCL information, yeah you're right, the information on the
support is limited, we need to improve that. The AndroMDA OCL 2.0
translation capabilities are handled through plugins we call
"translation-libraries". The plugins we have currently support writing
invariants and preconditions on our metafacade models, as well as
queries through OCL body expression (as you've mentioned already). If
you run andromda with an incorrect model you'll notice you'll get
validation errors at the end of processing, these are written in OCL in
the metafacade model and translated to java during the generation process.
You can also write preconditions on operations on spring services (this
could be easily added to any cartridge as it just calls the
andromda-validation-library for translation from OCL to Java). We're
planning on improving the OCL translation capabilities in the near
future. In regards to other resources, search the forum
(http://forum.andromda.org), I recently answered a question about good
OCL resources there.

Hi,
I’m new to Andromda and MDA in general. I’m trying to find some more
information on writing OCL queries. Specifically, which version of the
OCL syntax does Andromda support? Does Andromda support using OCL
constraints in all of its forms (pre and post conditions on
operations, guards, etc.) or just for wring queries to translate into
HibernateQL or EJBQL? Are there other resources out there besides the
limited information on OCL support in Andromda that I found in the
Spring how-to (not meant to be a jab, just an observation)?
Regards,
Thad Smith
