Projects assigned to this group but not mentioned here had no action requested or required - see for details.

Open Projects:

AES31-4-R Review of AES31-4-2015, AES standard for network and file transport of audio - XML Implementation of Audio Decision Lists
Status: Needs to synchronize with SC-02-08 changes to AES31-3.
There was a change to AES31-3 to correct a missing SMPTE label in an ADL ID field and this document will need a similar correction. It will be sent out for comment after the change.

The chair mentioned that there is an errant copyright statement which needs to be revised.

AES60-R Review of AES60id-2020, AES standard for audio metadata - Core audio metadata
Status: The document was published April 15th. The EBU counterpart is current stable.

AES-X098C Administrative metadata for audio objects - Process history schema
Scope: To collect information on all metadata issues pertaining to digital audio objects and all aspects of the digital documentation of digital audio objects.

Tormod is working to extend the RDF model and have a draft OWL prepared. Test data will be written as an RDF graph for testing and proof of concept.

AES-X155 AES standard for audio metadata - Production recording metadata set (iXML)
Scope: This document specifies a format for communicating file- and project-based production metadata between various stages of production and post production workflow.

Tormod asked for iXML example files. He is working on a mapping between iXML and AES60.

AES-X224 Best Practices for the Management of Embedded Metadata in Audio Files
Scope: To create a guide for manufacturers of audio hardware, software and computer platforms describing best practices for the management of metadata embedded in audio files.

On hold until the spring meeting in a final attempt to find someone interested in working on this. Richard Cabot will reach out to Chris Lacinak to ask if he can contribute. If we can't find any contributors, the project will be closed.


No further liaisons to discuss.

New Projects:

No new projects.

New business:

Because 03-12 is restarting SC-07-01 will move back into SC-03 as SC-03-07. There will also be a restart of SC-03-06.

The next meeting will be held online in May of 2021, in conjunction with the AES 150th convention.
