Overview of cModels & sDefs

Mapping Ruby Model Names to cModel Pids

This is how Ruby Model names will map to cModel pids (not currently implemented)

Primitives

A primitive is a fundamental atom object that bears an actual file payload. Most Hydra primitives will use the fileAsset cModel, putting their payload into a datastream called "content".

Current

hydra-cModel:fileAsset (formerly genericContent)
hydra-cModel:staticImage
hydra-cModel:jpeg2000

Posible Additions

hydra-cModel:dcAsset
hydra-cModel:modsAsset
hydra-cModel:modsImage

Higher Level Objects

Current

hydrangea-cModel:dataset
hydrangea-cModel:article

Possible Additions

stanford-cModel:etd

Service Definitions

Like a Java interface – a Service Definition (sDef) is just a list of methods/behaviors

Current

hydra-sDef:genericContent

methods:

• content – returns the content "payload" of the object

hydra-sDef:genericImage

methods:

• thumbnail
• screen
• max

Possible Additions

hydra-sDef:dynamicImage

methods:

• region
• resize
