No more than any other similar strategy. Mapping any territory
is a problem when the territory is not static. I once hiked about
five miles into backcountry only to find a resort, then checked
my USGS topo map. It was last updated in 1954.

And why? You're not being very explicit.
The reason why putting metadata into the document itself is IMO
a good solution is that mapping software that doesn't have access
to the author's metadata store can simply do a new scan of the
documents to obtain the *latest* metadata. If it's out of date,
that's an authoring problem. Keeping metadata that's not part of
a document current with the document is simply a matter of
matching generation or revision information. If the revision
number has changed on the document and it doesn't match the
metadata, you need an update. Absent a revision control system
or anything resembling author responsibility for such matters,
you can always checksum the thing.

You're a lot of help. You complain about someone else's strategy,
don't provide any reasons why is "sucks," and then ask others to
provide that for you. I don't find this particularly helpful
feedback. Please elaborate.
