| + # Skipping certificates agenda item because brunt and murillo absent -- will reschedule, maybe to end of next week (Friday?) |
| + # 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 |
| + # Update on data query/subset functionality (Tao and Spears) |
| + ** Rod gave an overview of the use of EML Data Source and cached queries |
| + ** Matt: can we use the existing Kepler-side infrastructure to implement EcoGrid-side data query by loading the EML-described sources into a relational db |
| + ** Jing: still need the DarwinCore Data source |
| + # Update on put interface implementation (Zhu) |
| + ** Bing gave overview of put implementation |
| + *** Noted that Metacat identifies metadata and data separately while SRB uses same id for both |
| + *** Client works, can use to upload |
| + *** Still need to know which system you are using so you use the API correctly |
| + **** Bing says this can be fixed on the client side |
| + *** Reviewed auth interface -- login, logout, genereates sessionid |
| + **** Eventually need to move to SSL for all services so that the communication is secure |
| + ***** Or use the GSI security layer |
| + **** how does this have to change to accomodate certificates? |
| + ***** once we have certificates, the ldap user DNs can be shared across systems (e.g., SRB, Metacat) |
| + **** Need to modify get and query interfaces to accept sessionId to allow for access to private records |
| + ***** need to allow anonymous query for some systems, should anonomous query and get use a different method or pass in a special userid (e.g., "public") |
| + |
| + !!! Action items |
| + # Matt will contact Bertram and Shawn about query translation needs, involve other EcoGrid folks |
| + ** reread Shawn's 'ant' paper for ideas |
| + # Rod will describe (in a bug) and implement a DarwinCore data source |
| + # Jing will describe and implement a new multi-node EcoGrid search for Kepler (with resultset integration) |
| + # Jing: test and install put and auth interfaces for metacat on ecoinfo2 |
| + # Modify get and query interfaces to accept sessionId to allow for access to private records |
| + ** Jing will enter a bug describing this |
| + # Bing will continue registry design and implementation |
| + # Mark Servilla will forward info to James and Michelle and they will let us know about a future call to discuss certificates and GSI |
