There are several options to make BridgeDB available in SPARQL.

BridgeDB is an identifier mapping service (http://www.biomedcentral.com/1471-2105/11/5) and currently being extended in the Open PHACTS project. It can map both URIs between databases (with different identifiers) as between databases with the same identifier (URL rewrites).

This page is to discuss options, and outline the issues. Involved as me, User:Eric, and Andra.

Option X

This option uses BridgeDB as an interactive intermediate.

   GRAPH <g1> { ?x <p1> ?g1_v } GRAPH <BridgeDB> { ?m <foo> ?g1_v ; <bar> ?g2_v } GRAPH <g2> { ?foo <p2> ?g2_v }
