This page documents some of the historical data issues in the Registers (relating to mistakes / corrections or similar).

Elements Register UL Re-Allocation

The entries in the v13 Elements Register whose UL item designators (last 8 bytes) begin “01.03.07” (“Operation Message Identifiers”) have had these bytes changed to “01.03.08”. No other bytes have been altered (not even the version byte). ULs with item designators (last 8 bytes) beginning “01.03.07” have now been allocated to new entries (“Channel Identifiers”). These changes are compatible with the defining documents for the affected Element entries (mainly because the documents defining the ASM entries under “Operation Message Identifiers” do not list the Element ULs as they are not used in practical implementations).

Label entries with ULs containing unexpected version bytes

“MXFGSEBUT3264STLByteStream”

The Label with UL urn:smpte:ul:060e2b34.0401010a.0d010301.03010000 was a new addition when a version byte of 0d would ordinarily have been used. However, the defining document had already been published with the version byte set to 0a and so this is how the entry has been set.

“TransferCharacteristic_ITU2020”

The Label with UL urn:smpte:ul:060e2b34.0401010e.04010101.01090000 was a new addition when a version byte of 0d would ordinarily have been used. However, a SMPTE Standard (SMPTE ST 2067-21:2014) had already been published with the version byte set to 0e and so this is how the entry has been set.

Labels Register UL Re-Allocation

The entries in the v12 Labels Register whose UL item designators (last 8 bytes) begin “0D.01.04.01.03” (“MXF Text-Based DM”) have had these bytes changed to “0D.01.04.01.04”. No other bytes have been altered (not even the version byte). ULs with item designators (last 8 bytes) beginning “0D.01.04.01.03” had already been allocated to AS-03 entries which were not added to the Labels Register at the time. The defining document for “MXF Text-Based DM” had already been amended appropriately.

Elements entry with UL containing unexpected version byte

The Element with UL urn:smpte:ul:060e2b34.0101010d.03010102.02150000 was a new addition when a version byte of 0e would ordinarily have been used. However, the defining document had already been published with the version byte set to 0d and so this is how the entry has been set.
