AES STANDARDS: DRAFT FOR COMMENT ONLY DRAFT REVISED AES60id-xxxx STANDARDS AND INFORMATION DOCUMENTS Call for comment on DRAFT REVISED AES Information Document for audio metadata - Core audio metadata This document was developed by a writing group of the Audio Engineering Society Standards Committee (AESSC) and has been prepared for comment according to AES policies and procedures. It has been brought to the attention of International Electrotechnical Commission Technical Committee 100. Existing international standards relating to the subject of this document were used and referenced throughout its development. Address comments by E-mail to [email protected], or by mail to the AESSC Secretariat, Audio Engineering Society, 551 Fifth Ave., New York NY 10176. Only comments so addressed will be considered. E-mail is preferred. Comments that suggest changes must include proposed wording. Comments shall be restricted to this document only. Send comments to other documents separately. Recipients of this document are invited to submit, with their comments, notification of any relevant patent rights of which they are aware and to provide supporting documentation. This document will be approved by the AES after any adverse comment received within six weeks of the publication of this call on http://www.aes.org/standards/comments/, 2020-03-03, has been resolved. Because this document is a draft and is subject to change, no portion of it shall be quoted in any publication without the written permission of the AES, and all published references to it must include a prominent warning that the draft will be changed and must not be used as a standard. AES STANDARDS: DRAFT FOR COMMENT ONLY The AES Standards Committee is the organization responsible for the standards program of the Audio Engineering Society. It publishes technical standards, information documents and technical reports. Working groups and task groups with a fully international membership are engaged in writing standards covering fields that include topics of specific relevance to professional audio. Membership of any AES standards working group is open to all individuals who are materially and directly affected by the documents that may be issued under the scope of that working group. Complete information, including working group scopes and project status is available at http://www.aes.org/standards. Enquiries may be addressed to [email protected] The AES Standards Committee is supported in part by those listed below who, as STANDARDS Standards Sustainers, make significant financial contribution to its operation.

Copyright ©2020 by the Audio Engineering Society Abstract This specification addresses the creation, management and preservation of material that can be re-used as originally produced, or may provide input material for new production projects. Material is expected to be exchanged between various organisations or between production facilities in a distributed environment. The core set of metadata presented in this specification is a co-publication of EBU Tech3293-2019 EBUCore, itself an extension to and a refinement of the Dublin Core. EBUCore is a minimum list of attributes characterizing video and / or audio media resources. An XML representation is used as this is the likely method that metadata would be implemented, for example in archive exchange projects using the Open Archive Initiative's Protocol for Metadata Harvesting (OAI-PMH). An AES standard implies a consensus of those directly and materially affected by its scope and provisions and is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an AES standard does not in any respect preclude anyone, whether or not he or she has approved the document, from manufacturing, marketing, purchasing, or using products, processes, or procedures not in agreement with the standard. Prior to approval, all parties were provided opportunities to comment or object to any provision. Attention is drawn to the possibility that somefor of the elements comment of this AES standard or only:information document see may be the subject of patent rights. AES shall not be held responsible for foridentifying latestany or all such patents. version Approval does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the standards document. This document is subject to periodic review and users are cautioned to obtain the latest edition. Recipients of this document are invited to submit, with their comments, notification of any relevant patent rights of which they are aware and to provide supporting documentation.
