| Handy API to execute OCL expressions from java code [message #1694965] |

Hi,
I would like to execute OCL queries and predicates from code. The context is that I have a metamodel, say myMetamodel.ecore, I have a model, say myModel.xmi, and I have a list of OCL constraints and queries defined over myMetamodel.ecore.
I would like to:
1) execute OCL constraints over myModel.xmi, and check if each constraint is valid (i.e., returns True) or not.
2) execute OCL queries over myModel.xmi and get the results of the queries.
My question:
1) what is the community suggestion for performing above tasks: using eclipse OCL API or other APIs like Dresden OCL (note that my metamodel files are in ecore format)
2) Which libraries (i.e. jar files), should I add to my project to be able to access Eclipse OCL and where can I get them.
3) Does any sample code (or tutorial) exist on the net that can be used as a starting point for doing above tasks.
4) where can I read and understand the concepts behind Eclipse OCL implementation in terms of its Interfaces and Classes ( I mean the implementation of OCL, and not the OCL language itself).
I really appreciate the community support.

Hi
You should find answers to most of your questions in the Eclipse OCL
Documentation.
http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.ocl.doc
There is no standardisation at the API level.
Eclipse OCL vaidation is integrated with standard EMF usage so you can
valoidate in the EMF-based editors. A Validity View provides finer
granied visulaization and entry to a debugger.
