Identifier

From Xcri

URI: http://xcri.org/profiles/catalog/1.1/identifier

Definition: An identifier element is used within the XCRI Course Advertising Profile to enable resources to be uniquely identified within a particular scope given within an encoding scheme.

Type: A String with an optional encoding-scheme specification.

Namespace: This is defined within the namespace: http://xcri.org/profiles/catalog

[edit] Example

 <identifier>http://www.bolton.ac.uk</identifier>
 <identifier xsi:type="ukrlp:ukprn">23424341414</identifier>

[edit] Guidance Notes

It is recommended that identifiers likely to be used by aggregators should be URLs that resolve to human-readable content.

Default identifier: Structures MUST NOT contain more than one identifier without an explicitly-defined encoding scheme, and this MUST be A Uniform Resource Identifier (URI) conforming to the URL scheme as specified by IETF RFC 3986.

Third-party identifiers: Use identifier with an encoding scheme to represent third-party indentifiers; use dc:subject to represent third-party codes that refer to multiple objects (e.g. subject classification codes, provider type codes)

[edit] Usage

Identifier is used in provider, course and presentation and other objects that require identifiers such as qualification, entryProfile, entryRequirements and venue.

For qualification: It is possible that Awarding Bodies will have permanent URLs for the qualifications they award; these would be preferable identifiers, but it is accepted that they may be difficult to collect, so internal identifiers are a practical alternative.
