R16: Updates to extension and annotation (and essenceTrack annotation) structure. #18

Closed pdpinch closed 14 years ago

pdpinch commented 14 years ago

Extension currently contains three discrete values (authority, type and value) within two fields. Also the extension can only contain key-value pairs and not hierarchical structures. Add third field extension and allow support for inline XML. Also since annotation is the extension of the instantiation, follow the same structure here as well.

with 5d0e20eabf4a35d9968d4d525d95f85f26990c45, broke extension into 3 elements: extensionType, extensionValue and extensionAuthorityUsed.

I'd suggest doing this also for the annotation, because many people are interested in recording things like PREMIS metadata for a specific instantiation.
