This is version 10.
It is not the current version, and thus it cannot be edited.
[Back to current version]
[Restore this version]
Jones, Spears, Tao, Servilla, Rajasekar, Zhu
This is a continuation of the previous agenda.
- Certificates and authentication
- EcoGrid query semantics
- handling EML version changes (2.0.0 vs. 2.0.1)
- translating EML and Darwin Core metadata queries
- Update on data query/subset functionality (Tao and Spears)
- Update on put interface implementation (Zhu)
- Review the 'put' interface via its WSDL
- Review the 'Authentication' interface via its WSDL
- Skipping certificates agenda item because brunt and murillo absent -- will reschedule
- 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 -- this is probably part of SMS layer, but how to deal with instance data (e.g., EML values)
- probably start with just crosswalks, then add instance data later
- implement this as an 'ontology server'
- e.g., takes an EML query in, gives a Darwin Core query back
- Shawn: says we should map to an integrated schema to avoin n^n mappings
- e.g., in ant example paper they map to the ontology
- Matt will contact Bertram and Shawn about query translation needs
- reread Shawn's 'ant' paper for ideas
