I am certainly interested in providing patches for the meta model component.
There is for example a very small, but not unimportant thing, I would very much like to change. Since I have been testing out the RDF layer, I noticed that MetaModelObjects are represented by "name", while RDF resources are represented by "uri". So out of the box it is not possible to create a triple stating that a certain resource has a certain class. So I would very much like to change the KEY_NAME of MetaModelObject into "uri". Another aspect to look at is layout strategy. The Rdf module has the option "dense" and "quad". A similar setup should in my opinion be used for the meta model module.
