Notes

1. Skipping certificates agenda item because brunt and murillo absent -- will reschedule
2. Ecogrid query semantics
• need ontology mapping between standards
• can Sparrow provide the necessary reasoning services?
• probably need to translate metadata instances as well as classes, so may need to populate the reasoner with al of the instance data (e.g., load EML into the reasoner)
• can existing query rewriting systems work? maybe...but probably would need to be customized or extended
• need to discuss with Bertram and Shawn, especially with regards to Sparrow
