I just got back from a meeting on this topic as it relates to NASA.
The presentations are here:

Here's a tinyurl in case that one gets broken up in transition

No specific consensus position has been compiled. However, there
seemed to be sentiment that a large data providing organization like
NASA should focus on providing as much metadata in as standard a way
as possible to ensure access to the data by future generations. That
pretty much means ISO metadata content standards today along with the
anticipated extensions for remote sensing data and imagery as they
emerge. There is less consensus on the actual best expression of that
metadata content (i.e. ISO 19139 XML encoding) and even less
consensus on the best catalog service standards to serve that metadata.
You might also stick your nose into the OSGeo data activity

KML and KML search as provided by Google are another avenue of
exploration. Google's search service is still a bit shaky but I
suspect that it will only improve over time. The real problem with
KML is that there are not many structured metadata slots and it's not
clear that they are indexing all of the KML tag content yet.

Dear List, Does any one have any real life production examples of
metadata catalogues in use? I mean: where metadata has been
created for a dataset, maintained and then used in a catalogue by
people to discover and get access to the dataset. I know there
are many projects that have attempted or proposed this - but has
anyone actually done, and continued to do, it? Cheers AlanK
