The formal notice on patent policy was read.

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

Open Projects:

AES60-R Review of AES60-2011, AES standard for audio metadata - Core audio metadata
Status: Revise to harmonize with EBU T3293 V1.9
Due to different voting procedures in EBU and AES over standards, the co-publication of EBU Tech 3293 «EBU Core» will be manifested as an information document, not a standards document.
The numbering of the two kind of documents are in the same number series so the document will keep its AES60 number. This will make sure that the updating process in EBU will not be delayed by the AES prosess. Inputs for the EBU Core work from the AES community is most welcome.

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. This scope includes field structures to describe and provide access to the audio content contained in digital files. It includes transfer, preservation and restoration information.
The standard has some overlap with other descriptive metadata standards, and the chair T. Værvågen will together with Egil Eide Ording make a draft to model X098C as an extension of AES 60/EBU core/EBU CCDM. The process have been delayed due to lack of resources due to a reorganization in NRK. The work will continue.

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. It may also have utility in other areas. The format, iXML, uses the XML standard for communication of tagged metadata. The XML-formatted metadata may be written to a data chunk inside a Broadcast Wave file, such as AES31-2, or some other suitable file type. iXML standardises the interchange of production information and provides an extensible framework to add new private or public data as needs develop, while permitting the specification to be expanded in a consistent and compatible manner.
Deferred to 2020 to await harmonization with updated 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.
No progress since last meeting, still looking for the people that can do this. Discussed again during the meeting, and the people present still believe it is important.
If no-one says they can do this task soon, the project will be closed.


No further liaisons to discuss.

The next meeting will be scheduled in conjunction with the AES 147th Convention, to be held October 2019 in New York, USA.
