This standard specifies a generic data model to represent the contents of the UL-based SMPTE registers. Examples of such registers are SMPTE 335M, SMPTE 395M or SMPTE 400M.

This generic data model also provides elements to hold administrative information used for the maintenance of the UL-based SMPTE registers. It includes rules how to extend the data model to represent the contents of specific UL-based SMPTE registers.

This standard also specifies how to encode the contents of individual registers as XML documents.

This standard does not define the relationships between the different registers. The data model is limited to defining the attributes that can be used by different SMPTE registers.
