I believe this actually references SMPTE RP 2057 "Text-Based Metadata Carriage in MXF" (implemented as part of commit f4061a21fffad4fdf8dbb2f193f0f0960b25421c).

o Added generic support for SMPTE RP 2057 "Text-Based Metadata Carriage in MXF"
o Re-factored AS-02 frame-wrap index write to use a common implementation
o Re-factored support for SMPTE ST 410 to use a common implementation (affects
o AS-DCP and AS-02 timed-text MXF (SMPTE 429-5)
o Patched several ambiguous integer casts.
o Added new essence type identifiers ESS_AS02_ISXD and ESS_AS02_ACES
o Fixed a bug wherein the Generic Container data tarck clip was instead being
o written as a DM track
o Fixed UL values DCDataDescriptor and ContainerConstraintSubDescriptor to have
o a byte 6 value of 0x53 (Tag Set) instead of 0x07 (coding sentinel)
o Added UL values 492 - 511 to the dictionary
o Added ApplicationSchemes and ConformsToSpecifications to the Preface set
o Added default initializer to MXF::LineMapPair
o Added sets DescriptiveFramework, DescriptiveObject, TextBasedDMFramework,
o TextBasedObject, GenericStreamTextBasedSet and ISXDDataEssenceDescriptor
o Added ISXD support and options '-G', '-u' to as-02-wrap
o Added ISXD support and option '-g' to as-02-unwrap

packs preceding partitions in AS-02 files.
o Fixed AS-DCP timed text writer, was creating DM Segment instead of SourceClip in the source package.
o Changed SourcePackage timecode track start to 00:00:00:00 (was 01:00:00:00)
o Fixed reference counting errors in asdcp.MXFWriter and asdcp.TimedTextWriter that were causing asdcp.MXFReader and asdcp.TimedTextReader (respectively) to remain allocated after all references had been deleted, thus leaking file handles and memory.
o Fixed broken arg parser (missing format token in format string for "EssenceType" argument) in TimedTextWriter

o The NamespaceURI property of AS-02 timed text files has been exposed in the API
and via as-02-wrap -P. This behavior replaces previous bad behavior, but puts
responsibility for selecting the correct value on the operator.
o Exposed CreatePNGNameId and CreateFontNameId subroutines in AS_02::TimedText
o Adjusted UUID generation based on PNG and font names to exclude paths by
inserting a call to PathBasename at each Id generation site

ambiguity. PHDR continues to use MXFGCP1FrameWrappedPictureElement.
MXFGCI1FrameWrappedPictureElement is supported for interlace.
o Added prototype PIDM dynamic metadata wrapping, config with --enable-phdr

global metadata
o Added support for 192, 200 and 240 fps images, includes 96, 100 and 120 fpe stereo
o Fixed raw essence detector for IMF Aux Data files
o Added missing MCA properties to MCALabelSubDescriptor (contributed by Ruppel)
o New MXF data type: LineMapPair
o Added default 0,0 VideoLineMap value when wrapping CDCI with as-02-wrap
o Added VideoLineMap property to GenericPictureEssenceDescriptor
o Added timed text unwrap support to as-02-unwrap (contributed by Ruppel)

o Improved integration of ST 377-4 MCA concepts with ST 429-2 static
labels.
o Added new EssenceType_t values for IMF/AS-02 track files.
o Added detection for AS-02 track files to ASDCP::EssenceType()
o Changed lots of "const char*" to "const std::string&" in the
APIs defined by KM_fileio.h and AS_DCP.h.
o Fixed VBR Delta Segment entries to correctly flag progressive
material.
o Fixed PCM unwrapping bugs in as-02-unwrap.

work will require changes in SMPTE ST 429-5 and perhaps other
standards work, so files created with this implementation are
"speculative". Publication of the revised ST 429-5 may not occur
until early 2015.
o Moved LocalFilenameResolver into the AS_DCP public API so that it
can be used by other modules including AS-02.
o Fixed wave wrapping UL in clip-wrapped AS-02 files. Renamed some
UL constants to reflect "clip" or "frame" wrapping.
o Re-factored JP2K_PDesc_to_MD() and MD_to_JP2K_PDesc() to work
with GenericPictureEssenceDescriptor objects.
o Fixed a bug that was suppressing PictureComponentSizing,
CodingStyleDefault and QuantizationDefault when writing the
essence descriptor in a JP2K file (AS-DCP and AS-02).
o Fixed the version byte on the following UL values:
StereoscopicPictureSubDescriptor
GenericPictureEssenceDescriptor_ColorPrimaries
GenericPictureEssenceDescriptor_ActiveHeight
GenericPictureEssenceDescriptor_ActiveWidth
GenericPictureEssenceDescriptor_ActiveXOffset
GenericPictureEssenceDescriptor_ActiveYOffset
o Added some essence descriptor options to as-02-wrap.
o Added TTML timed-text wrapping option to as-02-wrap.
o Changed bit rate display in asdcp-info from mebi-bits/s to
mega-bits/s.
o Added "SMPTE" / "Interop" format type display to asdcp-info.
o Modified asdcp-wrap to assume -L when wrapping timed-text (since
there is no MXF text wrapping for Interop.)
o Fixed missing-index-partion bugs for AS-02 files.
