7.2.4.4 describeRecordType operation
The describeRecordType operation is more completely specified in Table 18. provides a UML model of the describeRecordType operation that shows the complete Discovery
class with the DescribeRecordTypeRequest and DescribeRecordTypeResponse classes and the class they use. The operation request includes the attributes and association role
name listed and defined in Table 19. The normal operation response includes the attributes and association role name listed and defined in Table 20.
NOTE The describeRecordType operation corresponds to CG_Discovery.explainCollection operation in OGC
Catalogue version 1.1.1.
Table 18 — Definition of describeRecordType operation
Definition Allows clients to retrieve type definitions used by metadata of one or more registered
resource types
Receives Optional identifications of requested record types and of desired format
Returns Type definition document containing definitions of types used by the metadata of one or
more registered resource types. This type definition shall include the structure schema, queryables, element sets, and formats of the metadata used for one or more registered
resource types. The contents of the result of this operation depend on the types of metadata that can currently be used by registered resources.
Exceptions Missing Parameter Value, Invalid Parameter Value, Nonexistent type
Pre-conditions None
Post-conditions
Type definition document returned to requesting client, containing definitions of types used by the metadata of one or more registered resource types
