NSDL metadata for THREDDS datasets
We are working on a set of automated metadata generation tools to augment
the toolset associated with our Unidata LDM. The LDM is used to populate
many real-time data servers around the country -- including many THREDDS
server sites. While we are focusing on the metadata needed to connect
THREDDS clients and servers, we also want to incorporate some elements of
a "standard" discovery metadata set. We are aware of the detailed
standards of the FGDC, GCMD, those evolving at ISO as well as the ESML
definition at UAH.
But, as a place to get started and gain some experience with the metadata
generation tools themselves, we're looking for something simpler that
fulfills the basic requirements for NSDL and DLESE discovery metadata:
This is really the basic Dublin Core with a few educational extensions. I
am wondering if any of you have experience with mappings between the more
detailed standards and the NSDL/Dublin Core specs. In particular, we plan
to start with the types of data found on many THREDDS servers:
-- gridded data output from weather forecast models,
-- GOES satellite imagery, NEXRAD level 3 images, and
-- point source weather observations and balloon soundings from weather
-- climate data, .
Please let me know if you have experience with or suggestions for
generating Dublin Core records for these classes of data.
Thank you in advance.
