Hello, John,

I think we have a really great dialogue going on here. I will elaborate on
the points, below.

Right, but I think Scott addressed that and what we're trying to do here.
Mounting heads and aligning tape machines isn't that hard for me, but lots
of people don't do it themselves. Writing the software would be harder for me.

I think these tools are intended for smaller archives and people like me.
Larger operations will require you to use the rigorous tools that they
develop internally or purchase with rights management.

That is true--I haven't worked with that part of the latest Office all that

That wasn't what I meant. Entity A (me) transfers files for Entity B (Sound
Archive of Nowhere in Particular). I submit these files with
author/title/whatever metadata in them. It's all tied together. The SA of
NiP then ingests the files (essence and metadata) into their digital
storage system.

The Sound Archive of Nowhere in Particular can also send some of these
files off to the Aboriginal Cultural Heritage Centre of Nowhere in
Particular without having to extract pieces of a database, etc.

Totally agreed. I see the type of metadata in the BWF file as more
static/historic. The dynamic data--which, presumably, would be more
specialized to your collection would live in your database only and not be
written to the metadata chunk of the BWF files.
