(1.1) There is a need in the field of information technology for the unambiguous identification of objects to provide interoperability among information systems. Individual standards committees have divined, as part of their development of technical standards, classes of objects. Specific objects are the individual members of the class of objects. Registration is the process whereby unambiguous names are formally associated with objects. This may be done by an organization, a standard, or an automated facility. (1.2) Within the television and motion-picture industries, there is a need for engineering documents (standards, recommended practices, and engineering guidelines) which can easily and rapidly be extended to cover new requirements (dynamic documents). Such documents typically contain tables of values, parameters, or other entities that cannot be fully defined at the time the document is written. (1.3) Through a process described in this standard, the dynamic tables described above are established as registers to be administered by the SMPTE Registration Authority (SMPTE RA). (1.4) Dynamic documents are created using the same administrative practices as conventional SMPTE documents. Once a dynamic document is adopted as an engineering document, only designated entities within a dynamic document are subject to change by the dynamic document process. As with conventional engineering documents, the base document can be modified, but only in accordance with existing administrative practices. (1.5) Four types of registers are defined. These types differ in their procedures for adding or modifying the data contained within the registers. (1.6) In this standard, shall denotes a mandatory provision of the standard, should denotes a provision that is recommended but not mandatory, and may denotes a provision that is optional.
