I like the way both of you think. Sounds to me like you should both
take a look at SGML, ISO 8879:1986. And particularly at the SGML
Extended Facilities found in ISO/IEC 10744:1997 (see
http://www.hytime.org for pointers including the standard itself).
You will be surprised and pleased, I think, to discover that there is
such a beast, and, marvelous to say, it's already internationally
standardized. Of course, the paradigm assumes that there are
documents (SGML documents, of course) that declare the notations of
information resources, and that optionally declare the libraries
and/or applications that understand notations of resources. There are
also storage manager declarations that handle such things as
encryption, sealing, alternative character sets, compression,
containerizations such as tar, multimedia interleaving, etc. Check it
out. Some of us, at least, think it's the future of content
