The only way we have of adding additional metadata onto an object is via
the COMMENT command, which accepts a text string as input.

You can fill that with metadata as much as you like - the system never
touches that information other than to store it. So you can put an XML
fragment with Dublin Core tags in there etc.

I think your suggestion that we should have a/another field to store
structured metadata about objects is a good one. It would certainly
encourage better documentation in-database. Perhaps as an additional XML
column.
