System similar to D2RQ server, enabled data to be exposed to the Linked Data web

Can be run w/o modifying database, but also can add temp tables to help with query

uses SPARQL, provides RDF and HTML browsers

ways to generate data:

export data using scripts into a triple store, query that

map sparql to sql and query db directly

SeDA queries the rdb directly to answer sparql queries

SeDA builds a semantic model for relational schemas

Uses inference, example: transitive closure, subsumption inference to determine indirect shareholders of a company

for efficiency SeDA performs reasoning during query processing to avoid materializing inferred results in advance

SPARQL pattern tree redirected to DataLog Engine to expand it

a single SQL statement is generated for a SPARQL query

uses D2RQ mapping

temporary tables are added for user defined rules reasoning

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

Implemented automatic UML -> OWL transformation

automatically generate D2RQ maping from schema and ontology

based on eclipse modeling framework (EMF)

Ashok: Can we access papers?

Can ask any more questions by email.

No more calls for about 6 weeks, next call Sept. 5
