[Moose-dev] Questions concerning Property definition pragma

Hi, I am currently preparing a teaching course for next week (sorry, the support will be in French) explaining to the students what is a metamodel and how to create a new one with Moose. For this purpose, I have to explain how to create properties in Famix. For example: <MSEProperty: #name type: #String> <MSEComment: 'Basic name of the entity, not full reference.’> What are the accepted primitive types String and what else? It seems that Integer is not accepted. And what about Date or DateAndTime? In fact it seems that only String is accepted. In my case, the svn log metamodel, a Commit has a revision number (Integer) and a date (DateAndTime). Is there something I am missing? Thank you in advance for your help. Anne
