Categories of access and lifecycle patterns

[kjetilk]

One thing I started to think about during today's call, and that I would like to see is some language that defines certain categories of access and lifecycle patterns of metadata resources.

For example, an ACL resource has certain properties in that acl:Control applies to it, it is tied to the lifecycle of its resource, it has certain atomicity expectations, etc. An image, OTOH, has a metadata resource which is tied to it, but different permissions; a configuration metadata resource isn't necessarily tied to the lifecycle of its resource.

I think this boils down to a handful of orthogonal categories, and it seems to me that the spec would be clearer if we could define metadata resource types in terms of a few such categories, rather than having a sentence of prose for each.

This was also the motivation behind my tongue-in-cheek subatomic physics mental model, and I would like to see it made instrumental to improve the spec.
