Hi I'm wonder about child parent in rr:joinCondition in R2RML generated by virtuoso, suppose I have tow tables patient and Diagnose
Patient (ID, name, country....) -- ID is PK Diagnose (DiagnosesID, DiseaseID, PatientID,....) DiagnosesID is PK , PatientID is FK to patient table I have imported the tow tables by virtuoso wizard and it generate to me R2RML <#TriplesMapDiagnoses> a rr:TriplesMap; rr:logicalTable [ rr:tableSchema "emr" ; rr:tableOwner "emr-ODBC" ; rr:tableName "Diagnoses" ]; rr:subjectMap [ rr:termType rr:IRI ; rr:template " http://localhost:8890/emr/diagnoses/DiagnosesID={DiagnosesID}";; rr:class DB:Diagnoses; rr:graph <http://localhost:8890/DB#> ]; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:diagnosesid ] ; rr:objectMap [ rr:column "DiagnosesID" ]; ] ; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:diagnoses_has_disease ] ; rr:objectMap [ rr:termType rr:IRI ; rr:template "http://localhost:8890/emr/disease/DiseaseID={DiseaseID}"; ]; ] ; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:diagnoses_has_patient ] ; rr:objectMap [ rr:termType rr:IRI ; rr:template "http://localhost:8890/emr/patient/PatientID={PatientID}"; ]; ] . --patient <#TriplesMapPatient> a rr:TriplesMap; rr:logicalTable [ rr:tableSchema "emr" ; rr:tableOwner "emr-ODBC" ; rr:tableName "Patient" ]; rr:subjectMap [ rr:termType rr:IRI ; rr:template " http://localhost:8890/emr/patient/ID={ID}";; rr:class DB:Patient; rr:graph < http://localhost:8890/DB#> ]; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:id ] ; rr:objectMap [ rr:column "ID" ]; ] ; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:firstname ] ; rr:objectMap [ rr:column "FirstName" ]; ] ; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:dead ] ; rr:objectMap [ rr:column "Dead" ]; ] ; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:dead_date ] ; rr:objectMap [ rr:column "Dead_Date" ]; ] ; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:patient_has_disease ] ; rr:objectMap [ rr:termType rr:IRI ; rr:template " http://localhost:8890/emr/disease/Cause_Dead={Cause_Dead}"; ]; ] ; rr:predicateObjectMap [ rr:predicateMap [ rr:constant DB:patient_of_diagnoses ] ; rr:objectMap [ rr:parentTriplesMap <#TriplesMapDiagnoses>; rr:joinCondition [ r*r:child "ID" ; rr:parent "PatientID" *] ; ]; ] . the file R2RML attached also by this mail I want understand why the output R2RML in patient make the child is patient and parent is dianoses.????? diagnoses table it is has FK so I thinks it is a child and Patient it 's a parent, opposite to output !!! ----------------------------------- > Eng.Bassam Najeeb. >Software Engineer.
