Report of the SC-03-06 Working Group on Digital Library and Archive Systems of the SC-03 Subcommittee on the Preservation and Restoration of Audio Recording meeting, held in Paris, France, 2006-05-22

The meeting was convened by C. Chambers.

The agenda and report from the 118th convention meeting were accepted as written.

Development Projects

AES- X098 Audio Metadata
The documents (parts A, B and C) tabled were confusing, as the document titles do not seem to match the divisions that had originally be set up. It appears that documents "A" and "B" may have been merged. The meeting struggled to understand the current status of the separate parts of the AES-X098 documents, however the latest postings were studied and the meeting agreed that this seems very close to completion. The meeting felt that the author had done a fantastic job in getting the documents to this stage.

The original documents divisions are shown below but it was agreed this should be aiming at PWD by next October.

• AES-X098A: Descriptive metadata for audio objects
• AES-X098B: Administrative metadata for audio objects
• AES-X098C: Administrative metadata for audio objects �Process history schema

The PWD date was advanced to next October.

A discussion ensued on the requirements for the recording of the physical parameters of Optical media such as focal length to be recorded in the metadata about recordings or if, in reading the medium, this information can be deduced from the medium.

The next stages are to check the formatting and aligning it with metadata registries before issuing it as a PWD. This issue is also being discussed in SC-03-07.

The SMPTE metadata dictionary was referred to and the possibility of this document being linked to the SMPTE registry more formally was also discussed by being a part of class 13 of this large metadata set. This dictionary is publicly available from the SMPTE web site It was proposed that this document could be mapped into the SMPTE dictionary where elements already fit and any other items the AES wish to standardised could be put into a class 13 set as an AES entry. This proposal is put to the working group.

The meeting formally congratulated David Ackerman for his work on this document.

It was established that the AES is able to publish an XML schema both on line and as a part of the standards publication process.
