Another interim version of MOLES, the main changes here are to
- make clear that dgEntity and dgBase are abstract (never instantiated),
- for the moment at least, not all moles entities are discoverable
- explicitly include attributes necessary for the mandatory ISO elements.
I expect the next version will move to specialising from Atom entities rather than GML feature types (although we’ll explicitly allowing GML feature types to be encapsulated in the atom content).
