Most Nodes in Class 13 are registered for public use by named organisations – entries under these Nodes are controlled by the relevant organisation.
However, under the Class 13 Node registered to the AAF Association / AMWA there are some Nodes which are actually controlled by SMPTE (for historical reasons). Therefore, all entries in SMPTE Metadata Registers with ULs that have bytes 9, 10, 11 set as follows are controlled by SMPTE:
0d.01.010d.01.020d.01.030d.01.040d.01.050d.01.06
