Internal Representation of resources
Here's an example of a LDPRv - what signifies that it is a LDPRv is that it has a `fedora:hasVersions` triple. This is the current behavior of the Modeshape Fedora and doesn't seem to need any change, other then maybe how the `fcr:versions` triple is created.

... triples from original resource at the time of versioning...
or, if we keep them separate, it might look like this:
(I'm not clear on how a binary and it's metadata would be represented)
ldp:contains </path/to/xyz/fcr:versions/12345/version> ,
</path/to/xyz/fcr:versions/12345/version/fcr:metadata> ;
