'''SWObjects''' is a [[free software|free]] and [[open source]] [[Semantic
Web]] toolkit for query transformation.

== Functionality ==
=== Ontology Projection ===

Given a rule R12 translating from ontology1 to ontology2, a query phrased in
terms of ontology2 can be transformed to work on ontology1. The result of
this is you have no need to materialize ontology transformations, merely
declare them by rule.

== Rule styles ==

[[d2r (programming language)|d2r]] uses RDF expressions associating RDF
predicates to relational tables/attributes.
SWObjects uses [[SPARQL]] CONSTRUCT rules.

{{Anchor|requirements}}

== Requirements ==
* [[C++]]
* [[Yacc]] ([[GNU bison|Bison]])
* [[Lex programming tool|Lex]] ([[Flex++]])
* [[Boost C++ Libraries|Boost]]
* [http://dclib.sourceforge.net/ dlib] (required for SPARQL_server)
