Note that's only appropriate if "metadata" includes some sort of long 
alternative to/description of the image. Otherwise it's not a long 
description. Wikipedia misuses LONGDESC to point to mere metadata (e.g. 
date, file type, licencing information) and this is an example of 
LONGDESC "poisoning".

The more microformat-y way of doing things is to put the metadata on the 
image page itself:

    * http://microformats.org/wiki/principles
    * http://microformats.org/wiki/include-pattern-faq

There's a proposed "figure" microformat that this may be feedback for:


It already has items for certain sorts of metadata.

What sort of metadata are you proposing to reference?

What actual problem are you trying to solve?
