SPARQLPropertyPath

SPARQLPropertyPath[start, {p1,p2,…}, end]

is a pattern object that represents a path in a RDF graph that starts at subject start, visits edges with predicates pi and ends at object end.

Details and Options

  • Each pi can be a predicate URL or a pattern.
  • The arguments start and end can be a URL or a SPARQLVariable and end can also be a literal like a number or string.
  • SPARQLPropertyPath[start,{p1,p2,…},end] matches a path {RDFTriple[a,f1,b],RDFTriple[b,f2,c],…,RDFTriple[y,f2,z]} if MatchQ[{f1,f2,…},{p1,p2,…}] returns True and start is either a SPARQLVariable or a and end is either a SPARQLVariable or z.
  • The pi can be any combination of the following forms:
  • URL[…]a predicate path
    SPARQLInverseProperty[…]an inverse path
    Sequence[…]a sequence path
    Alternatives[…] (|)an alternative path
    RepeatedNull[…] (...)a zero or more path
    Repeated[…] (..)a one or more path
    Repeated[…,{0,1}]a zero or one path
    Except[…]a negated property set (only for predicates, inverse predicates and alternatives thereof)

Wolfram Language code: Needs["GraphStore`"]

Specify family relations:

Wolfram Language code: ex[s_] := URL["http://example.org/" <> s];
Wolfram Language code: familyGraph = RDFStore[{ RDFTriple[ex["scarlett"], ex["hasFather"], ex["john"]], RDFTriple[ex["scarlett"], ex["hasMother"], ex["lily"]], RDFTriple[ex["scarlett"], ex["hasHobby"], ex["swimming"]], RDFTriple[ex["john"], ex["hasFather"], ex["james"]], RDFTriple[ex["john"], ex["hasMother"], ex["nora"]], RDFTriple[ex["john"], ex["hasHobby"], ex["volleyball"]], RDFTriple[ex["lily"], ex["hasFather"], ex["alex"]], RDFTriple[ex["lily"], ex["hasMother"], ex["stella"]] }];

Find the grandparents of Scarlett:

Wolfram Language code: familyGraph//SPARQLSelect[ SPARQLPropertyPath[ex["scarlett"], {ex["hasFather"] | ex["hasMother"], ex["hasFather"] | ex["hasMother"]}, SPARQLVariable["grandParent"]] ]

The same query using triple patterns and UNIONs:

Wolfram Language code: familyGraph//SPARQLSelect[{ RDFTriple[ex["scarlett"], ex["hasFather"], SPARQLVariable["parent"]] | RDFTriple[ex["scarlett"], ex["hasMother"], SPARQLVariable["parent"]], RDFTriple[SPARQLVariable["parent"], ex["hasFather"], SPARQLVariable["grandParent"]] | RDFTriple[SPARQLVariable["parent"], ex["hasMother"], SPARQLVariable["grandParent"]] } -> "grandParent"]

Wolfram Language code: Needs["GraphStore`"]

Specify relationships between people and how the used properties are related:

Wolfram Language code: rdfs[s_] := URL["http://www.w3.org/2000/01/rdf-schema#"]; ex[s_] := URL["http://example.org/" <> s];
Wolfram Language code: friendsGraph = RDFStore[{ (* vocabulary *) RDFTriple[ex["hasGoodFriend"], rdfs["subPropertyOf"], ex["hasFriend"]], (* data *) RDFTriple[ex["bob"], ex["hasFriend"], ex["alice"]], RDFTriple[ex["bob"], ex["hasGoodFriend"], ex["frank"]], RDFTriple[ex["alice"], ex["hasFriend"], ex["carl"]] }];

Find all friends and good friends of Bob:

Wolfram Language code: friendsGraph//SPARQLSelect[{ RDFTriple[ex["bob"], SPARQLVariable["friendProp"] , SPARQLVariable["friend"]], SPARQLPropertyPath[SPARQLVariable["friendProp"], {rdfs["subPropertyOf"]...}, ex["hasFriend"]] }]
