+
+ !!! Notes
+
+ # EcoGrid registry
+ ** need registry metadata
+ *** Raja suggests need name-value pairs
+ *** previously discussed need for structured metadata, including coverage, but hard to keep updated
+ *** Raja argues the more structured registry metadata is not needed, at least from the UI perspective
+ ** Do we need to reimplement using globus? Probably not? Globus registry still not presistent. Our metacat implementation is persistent.
+ ** Are there specific metadata fields we need to help users choose nodes to search
+ ** Action items
+ *** Extend registry metadata to accept xml metadata documents (Bing, Rod)
+ *** Establish short list of standard attributes, extend UI to accomodate them (Bing, Rod, Matt)
+ **** Start at Dublin core and extend it
+ *** Fill out metadata for specific nodes (Bing, Rod)
+ *** Make registries broadcast new registration change events (Bing, but lowest priority)
+ # EML Metadata for SRB-stored data sets
+ ** Option 1: store EML in metacat and point at SRB object (preferred)
+ *** Figure out where Deana is storing her data (same as LTER)?
+ *** How to coordinate authentication and access control
+ **** Use GSI certificates
+ **** Synchronize SRB/Metacat user lists and access control changes
+ ** Action items
+ *** Contact Deana about putting data in SRB and metadata in Metacat (Matt)
+ *** Verify that accounts can be synchronized between Metacat and SRB (Bing)
+ # Identifiers
+ ** Agreed on using LSID format for all EcoGrid identifiers
+ *** need to retrofit existing EcoGrid services to use them
+ ** Action items
+ *** Fix get, put, query to use LSIDs everywhere (Bing, after registry stuff)
+ *** Coordinate with Thau on establishing an LSID server (Rod)
+ *** Talk with Dave Vieglais about using LSID's for Darwin Core records (Matt)
+ # Overview of Ecogrid web UI
+ ** Tekell gave overview of progress (see page linked above)
+ ** has need for EcoGrid Level II interfaces to do resultset merging
+ ** Q: do we have interfaces defined for getting summary counts back instead of results
+ # Next Conference call: September 17, 2004 11am PDT
