ADAPT - Compound Identifier Discussion

CompoundIdentifier is a class that enables associating one or more unique identifiers (plus information regarding the creator of the identifiers) to the various objects in the application data model. Compound identifiers will be used by every class that needs to "stand alone" and be referenced by other objects.

CompoundIdentifier

Attribute	Type	Multiplicity	Description
ReferenceId	Integer	1	A unique (integer, locally-scoped) ID for a particular instance of an object.
UniqueIds	UniqueId	0..n	Can be created in a distributed fashion (i.e., without a centralized naming authority, as long as there is reasonable certainty of its uniqueness. Note that a given object can be associated with multiple unique IDs.

Example (represented as XML) of something that has two unique identifiers for it, each produced by a different source.

UniqueId

Attribute	Type	Multiplicity	Description
Id	String	1	Can be created in a distributed fashion (i.e., without a centralized naming authority, as long as there is reasonable certainty of its uniqueness.
~~CIType~~	~~CompoundIdentifierType~~	1	~~An enumeration. Its possible values are:~~ ~~UUID~~ ~~GLN~~ ~~URI~~ ~~String~~ ~~Long~~
IdType	IdTypeEnum	1
Source	String	0..1	Source may be a URI or GLN; in principle, this should be a unique string off of some controlled vocabulary. This can be a GLN or a URI.
SourceType	IdSourceTypeEnum	0..1	GLN URI Required if Source is Present.
