Hi Prateek, It would help if you provide more detail. If you run this query from Qconsole, against which database are you running it then (the dropdown at the top of QConsole)? And does this database contain triple data? You can discover that using the Explore button which should reveal XML triple files, or using count(cts:triples()) in a new Qconsole query against the same database.
Note that your ruleset needs to be stored in the schemas database that is connected to the documents database that you are using..

Specify ruleset programmatically using a sem:ruleset-store (see http://docs.marklogic.com/guide/semantics/inferencing#id_pgfId-920824) 2.

Here is the scenario: 1. create data PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX place: <http://example.com/places/> PREFIX ex: <http://example.com/> PREFIX bank: <http://example.com/banks/> INSERT DATA { GRAPH <http://marklogic.com/semantics/sb/banks/inf-1> { bank:1001 rdf:type ex:bank ; ex:name "rbs" ; ex:service "loan" , "asset management" , "fx" ; place:name "london" . bank:1002 rdf:type ex:bank ; ex:name "rbi" ; ex:service "loan" , "retail banking" , "guide lines" ; place:name "delhi" . } } #------------- Define some places and their relationships------------- DROP SILENT GRAPH <http://marklogic.com/semantics/sb/places/inf-1> ; CREATE GRAPH <http://marklogic.com/semantics/sb/places/inf-1> ; PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX place: <http://example.com/places/> PREFIX ex: <http://example.com/> INSERT DATA { GRAPH <http://marklogic.com/semantics/sb/places/inf-1> { place:1001 rdf:type ex:country ; ex:name "uk" ; ex:isin "Europe" . place:1002 rdf:type ex:city ; ex:name "london" ; ex:isin "uk" . } } 2. Query w/o inference PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX ex: <http://example.com/> PREFIX bank: <http://example.com/banks/> PREFIX place: <http://example.com/places/> SELECT ?b FROM <http://marklogic.com/semantics/sb/banks/inf-1> WHERE { ?b rdf:type ex:bank ; place:name "london" } 3. I know how to use inference via creating ontology data: PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX ex: <http://example.com/> INSERT DATA { GRAPH <http://marklogic.com/semantics/sb/banks/inf-1> { ex:city rdfs:subClassOf ex:country . } } ------------------------- 4. Now, what I am trying to do is; achieve this via creating custom rules file. I have created "bankAt.rules" file under schemas database. Here is the code: PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema/> PREFIX ex: <http://example.com/> PREFIX gn: <http://www.geonames.org/ontology/> rule "bankAt" CONSTRUCT { ?bank ex:bankAt ?place2 } { ?bank ex:bankAt ?place1 . ?place1 gn:parentFeature ?place2 } I dont know how to use this rules file in my sparql query. I would be really helpful if someone can just list down the steps on "how to use this rule in sparql query".
