public interface Aggregateable

Aggregateable is used for an OsidObject to indicate that some or all of the definition is based on an included set of other OsidObjects which are directly accessible and do not exist outside the context of the parent object. Aggregateables allow for an OsidObject to stand alone without knowledge of the originating service.

An Asset is an example of an aggregate by including the AssetContents . An Asset also contains a provider however in this case the provider is categorized as a simple data attribute of the Asset that can be changed by updating the Asset using an AssetForm . The AssetContent differs in there exists a explicit mapping to the Asset managed through an OsidSession but accessible directly within the Asset to enable its consumption outside the Repository OSID.

This marker has little practicality other than to identify a service pattern that is neither a data attribute nor a separately accessible relationship or mapping.
