This section of the SMPTE Registration Authority lists the XML namespaces and associated elements (XSD, WSDL...) specified by SMPTE Engineering Documents. 

The XML namespaces are arranged according to the hierarchical components of their URI name, which does not necessarily map to their defining documents. For instance, while both of the following namespaces share a common hierarchical part, the first is defined in ST 2052-1:2013 while the second is defined in RP 2052-10:2013.

Use of this information without consulting the corresponding SMPTE Engineering Document is NOT supported. Interoperability will generally require comformance to additional guidelines and constraints specified in the Engineering Document prose.

Unless specified otherwise, XML elements are provided subject to the following license:
