Abstract
AbstractQuery federation is a way to make use of distributed data sources on the Web, including many SPARQL endpoints as well as relational databases. SWObjects makes use of mapping rules represented as SPARQL Constructs to dynamically rewrite the terms and predicates of a SPARQL query into corresponding terms in another vocabulary and connect the resulting query with the appropriate service for answering the query. SWObjects can also rewrite SPARQL queries in SQL, effectively including relational databases alongside SPARQL endpoints in a linked data federation. The author of SWObjects, Eric Prud'hommeaux, is the W3C staff contact for the W3C Health Care and Life Sciences Interest Group (HCLS IG) and will give the tutorial via a teleconference connection, with assistance from Helena Deus (University of Texas) and M. Scott Marshall (HCLS IG co-chair).
