Re: [xwiki-dev] [ArchitectureV2] Model proposal

Hi, Starting from today I'm going to spend some time every week on the V2 Architecture/Redesign. Today I'd like to start at the heart of the topic with the domain model. Here's my proposal: * Model classes are classes representing the XWiki model. The main classes are: - Farm - Wiki - Space - Document - XObject - XClass

- (probably lots of others) * As you can see I'd like to introduce the Space and Farm objects * We create a model/ build module in trunks-devs/xwiki/model for storing model classes * Model classes cannot access other classes outside of the model/ module. They are meant to be used by components to provide services but they shouldn't provide services themselves. They can methods to manipulate their fields and they can call each other but they cannot call outside of their model. * We use the org.xwiki.model package for storing Model classes * These model classes are all user public (API) WDYT?

Barring any negative feedback I'll start implementing this today and in the coming days. One question that remains unanswered in my mind is how do we integrate back these model classes into the V1 architecture. I think we should be able to retrofit the existing classes to use these classes by composition. For example the Document object could have 2 fields: one org.xwiki.model.Document and one org.xwiki.model.Space. The XWiki object could have 2 fields: Wiki and Farm, etc. I'm not sure how this would work out though. Any idea is welcome. Thanks -Vincent
