I fully concur, after 20 years doing SDI, I've become convinced that metadata catalogs have become a "displacement activity" and we should derive metadata during the process of putting data online. Most other metadata records (in the SDI sphere) should be seen as an admission of guilt - I havent made this available even though you (the taxpayer) paid me to collect it. > > How?

FYI I'm currently leading research projects looking at ways to make richer structured metadata about data content visible. The "value" metadata discussed here will be vital for finding data in a large (well-populated) SDI environment. I'd just love to see the data out there at all! > > thanks for listening. > thanks for sharing..
