> The way that DataContexts are currently handled with the DataContextFactory class is not ideal, or scalable, IMO. It basically requires that users have a metamodel which includes data contexts which they have no intention of using. By implementing pluggable data contexts, developers would be able to configure which data contexts they require and at the same time provide the jar files necessary to implement the data context. This would require definition of a DataContextFactory interface (not class) and each data context plugin would implement it for the various signatures required.
> PS: I'd be happy to implement this (and of course the Non-extensible DataContextFactory)
