15:07:38 <joebetz> Minutes approved from 2 weeks ago?  No objections.  Approved.
15:08:11 <joebetz> XG Logistics:  F2F  on 30th and 31th of Oct.  about 12 people will attend
15:08:50 <joebetz> Action item: wolfgang hub for F2F
15:10:03 <joebetz> September the 5th will be next call, talk about what our deliverables
15:10:43 <joebetz> Email good communication about deliverable until we talk again

15:12:07 <JimM_> Hi, Andrew
15:12:21 <Andre1> Hi
15:12:36 <Andre1> Sigh, completely lost track of time
15:12:41 <JimM_> Easy to do!
15:14:30 <joebetz> Literature survery:  A couple more papers,  will update wiki and send mail.
15:15:58 <joebetz> XG deliverables:  any comments?  Send mail.

15:28:00 <joebetz> System similar to D2RQ server,  enabled data to be exposed to the Linked Data web
15:29:34 <joebetz> Can be run w/o modifying database, but also can add temp tables to help with query
15:30:20 <joebetz> uses SPARQL, provides RDF and HTML browsers
15:33:43 <joebetz> ways to generate data:  
15:33:46 <joebetz> export data using scripts into a triple store, query that
15:34:31 <joebetz> map sparql to sql and query db directly
15:35:58 <joebetz> SeDA queries the rdb directly to answer sparql queries
15:38:33 <joebetz> SeDA builds a semantic model for relational schemas
15:40:17 <joebetz> Uses inference, example:  transitive closure, subsumption inference to determine indirect shareholders of a company
15:42:54 <joebetz> for efficiency SeDA performs reasoning during query processing to avoid materializing inferred results in advance
15:44:48 <joebetz> SPARQL pattern  tree redirected to DataLog Engine to expand it
15:45:00 <joebetz> a single SQL statement is generated for a SPARQL query
15:45:28 <joebetz> uses D2RQ mapping
15:46:00 <joebetz> temporary tables are added for user defined rules reasoning
15:49:02 <joebetz> Inference subtrees are added to the SPARQL syntax tree,  for recursive rules, structure cannot be in syntax tree but for all else put the logic in the tree
15:57:32 <joebetz> Implemented automatic UML -> OWL transformation
15:58:37 <joebetz> automatically generate D2RQ maping from schema and ontology
15:59:06 <joebetz> based on eclipse modeling framework (EMF)
16:01:49 <joebetz> Ashok:  Can we access papers?
16:03:04 <joebetz> Can ask any more questions by email.
16:03:14 <joebetz> No more calls for about 6 weeks, next call Sept. 5
