RDF Rules can be written as SPARQL construct-where rules (former Corese rule syntax is also supported):
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE rdf:RDF [ <!ENTITY rdf "http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <!ENTITY rdfs "http://www.w3.org/2000/01/rdf-schema#"> <!ENTITY rul "http://ns.inria.fr/edelweiss/2011/rule#"> ]> <rdf:RDF xmlns:rdfs="&rdfs;" xmlns:rdf="&rdf;" xmlns = '&rul;' > <rule> <body> construct { ?x rdf:type ?d } where { ?p rdfs:domain ?d ?x ?p ?y } </body> </rule> </rdf:RDF>
