Report of the meeting of the SC-03-06 Working Group on Digital Library and Archive Systems of the SC-03 Subcommittee on Preservation and Restoration of Audio Recordings, held in London, UK., 2011-05-15.
NOTE this working group's meeting was held jointly with that of SC-03-07, although agendas and reports were handled separately
The meeting was convened by SC-03 chair C. Chambers.
The agenda and the report of previous meeting, held in San Francisco, CA., US., 2010-11-06. were approved as written.
Development Projects
AES-X098B Audio object structures for preservation and restoration
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.
status: Currently out for public Call for Comment as AES57-xxxx. Closes end of June 2011.
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.
Status: The draft is currently being updated; aiming for PWD following the New York meeting.
An early version is available on the FTP site. David Ackerman is working on a finalized version for the New York meeting to be held in October. T. Vaervagen from NRK offered to assist Ackerman in producing or reviewing any schemas for this document.
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 Format file, such as AES31-2, or some other suitable file type. iXML standardizes 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.
In discussion, it was suggested that the area of the text that identifies the upper or lower case issues should be altered to say that the parser should read either upper or lower case but the schema for this standard will be written in upper case. It is believed that this will cover all existing implementations of iXML. At the last meeting it was noted that both Ackerman and Vaervagen had produced draft schemas for AES-X155. It was hoped that they could discuss producing a finalised version the summer so this could be posted in good time before the New York meeting in October. It was noted that the section on speed was confusing and Annex E should have further examples added for clarity the differences from those in section 5.31. The Standards secretary will work on this.
Liaisons
It was proposed that they could be a liaison possibility with AMWA (www.amwa.tv). This will be considered and discussed further.
New Projects
No new projects were received or proposed.
New Business
There was no new business
The next joint meeting will be scheduled in conjunction with the AES 131st Convention in New York, 2011-10.
