Handle Presentation 4

[donaldgray]

How do we do this? Add a new namespace and include types in there?

What differences do we need to model?

Can we share anything between P3 and P4?

Unlike 2->3, the model doesn't change much (mostly additive). But there are some stricter rules for annotations and some new classes and properties.

In the same way that Vault internally uses a P3 model but can serialise as P2 or P3 (with some restrictions), iiif-net could have a shared P3/4 model with different serialisation behaviour.

Perhaps.
