I need to classify and mark my content types. As example I have three content types for group messages in OG, ten content types which used as UC products, etc. So I need to add taxonomy and fields to my content types (NOT for nodes of content types, but to content types!) and then filter them. As example I could show only OG message types, or only product types, or only products which are clothes etc. So I thing I need a module which turn content type to something like entity.
Is there any module which implements such feature?
It is hard to search such module, because if I search like "add fields to content types" I see results how to add fields to nodes of content types, which will be populated in node forms. But I need to add fields to content type form, to classify and mark content types, not nodes of content types.
