I agree, if that is about settling on the way of writing arbitrary
key-value pairs within Gemini documents.  That would be something
analogous to what would be the meta element in XHTML:'

	<meta name="..." content="..." />

The spec there provides the element.  The people using the spec fill in
the data themselves through their own choice.  It is then up to them to
use or write software on their site which takes advantage of it to offer
one or more ways to navigate the accrued metadata.  Or not.

The actual contents of the key-value pairs, the actual metadata itself,
would not be part of the spec, not even the keys.  It would not be
appropriate to try to impose a custom vocabulary or even any existing
schemes like the Library of Congress Subject Headings (LCSH), Medical
Subject Headings (MeSH), Universal Decimal Classification (UDC), L??v,
or any other vocabulary.
