URN |
1..1 |
The URN of the entity matching the DDI URN pattern associated with the value of the attribute typeOfIdentifier (Canonical or Deprecated). |
|
Agency |
1..1 |
This is the registered agency code with optional sub-agencies separated by dots. |
|
ID |
1..1 |
The ID of the object. This must conform to the allowed structure of the DDI Identifier and must be unique within the declared scope of uniqueness (Agency or Maintainable). |
|
Version |
1..1 |
The version number of the object. For the identifiable object this is the version number of its parent versionable at the point of creation or alteration of the non-administrative metadata of the identifiable. Versionable and Maintainable items increment their version number whenever the non-administrative metadata contained by the object changes. |
|
UserID |
0..n |
Allows for the specification of identifiers other than the specified DDI identification of the object. This may be a legacy ID from DDI-C, a system specific ID such as for a database or registry, or a non-DDI unique identifier. As the identifier is specific to a system the system must be identified with the UserID structure. |
|
UserAttributePair |
0..n |
A system specific user defined property of the object expressed as a key/value pair. As this is specific to an individual system the use of controlled vocabularies for the key is strongly recommended. |
