AES-X098B: Administrative metadata for audio objects
The document was submitted to the Standards Manager for secretariat formatting. Various methods were discussed for reducing the clutter in the document due to the number of nested clauses. Xlink representations were presented as a possible alternative to deeply nested clauses in the layout. The Standards Manager was left to explore that option and use it if it would help clarify the layout of the document.

The desire for a standard interface was expressed by G. Reid. A discussion of the model-view-controller design pattern ensued. The result is that the committee will initiate a new project to produce a report that offers guidance on default design criteria for application programmers wishing to implement the draft-standard. This is more desirable than trying to pre-define the use of the data model that the document sets out describe.

The need for a permanent URI to host the schema was expressed. This must be established before the document is published given that it must reside within the schema itself.

A brief discussion ensued about the representation of TCF in XML. It was decided that we would stick with the more verbose method currently used in the document rather than a simple string. The feeling was that it is better to have the stricter data model that is presently described in the draft standard.

There was no new work on X98C.


IASA liaison: It was decided that the informal liaison with IASA should be retired as a formal project. This is simply an administrative matter. It is expected that the informal relastionship that exists now will continue to exist.

New Business

A new project was accepted to produce the report mentioned under the discussion of X98B. There was no other new business.

The next meeting will be held in New York in conjunction with the ASE123rd Convention, 2007-10.
