A schema is a collection of attribute definitions that describe the
contents of an entire or partial resource, for example,
urn:ietf:params:scim:schemas:core:2.0:User. The attribute definitions
specify the name of the attribute, and metadata such as type (string, binary), cardinality
(singular, multi, complex), mutability, and returnability.

In general, attributes are identified by prefixing the attribute name with its schema uniform resource name (URN), separated by a colon (:) character. For example, the core User resource attribute userName is identified as urn:ietf:params:scim:schemas:core:2.0:User:userName.
The identity domains REST API includes the following schema URNs:
