Well, it is structured data about the resource which somehow secondary as
opposed to primary. But it is important that it is structured.
The term is used by different people in different ways. One use, which I
think is the one which Aida aludes to, is data about the metadata. This is
the most widespread use outside of the IMS/LOM learning technology world.
In the LOM, though, this is called meta-metadata.
Another use is metadata from anything other than the primary source: so the
author/publisher would provide some metadata, e.g. Title, ISBN Number,
Author Name, and other people (users, cataloguers) would provide other
metadata, e.g. a description of the resource, the retail cost etc.
A third use, is that it gives information on how the resource is used, for
example the metadata which Google keeps on a resource might list how many
other pages link to the page being indexed. Finally, as a sort of mixture
of the last two, it's sometimes used to mean subjective opinions and
contextual reports about the the resource.
Given the over-use of the term "metadata" and the uncertainty about what is
meant by secondary, I would avoid using the term.
