Agreed. That's what PICS-SE is all about.

But they are a short term solution IMHO. Not powerful enough, not
extensible enough, not flexible enough, and last not least, bloat.

And these include all kinds of documents, including HTML, for which
neither author nor publisher nor anybody else with access to the
source has interest, time, or resources to provide metadata.

PICS has a transport mechanism for metadata

- in the HTTP Header
- in 1 (yes _one_) META tag
- separately from the document

PICS-SE adds an object oriented framework that enables metadata
transport with unlimited mileage. *Please* Check it out.
