Property Paths

SPARQL property paths enable users to examine the patterns between properties in the data. Property paths reveal the routes between nodes in a graph.

Syntax

Specify property paths in the predicate part of a triple pattern. Combine predicates using the operators described in the table below. For more information, see the W3C Property Path specification.

Construct	Expression Name	Description
<URI>	PredicatePath	A predicate URI in a triple pattern matches a path length of one.
**^**path1	InversePath	Matches on backwards paths--subject to object.
path1**/**path2	SequencePath	Matches on forward paths--path1 followed by path2.
path1**	**path2	AlternativePath
path1*****	ZeroOrMorePath	Connects the subject and object of the path by zero or more matches of path1, i.e., path1 repeated zero or more times.
path1**+**	OneOrMorePath	Connects the subject and object of the path by one or more matches of path1, i.e., path1 repeated one or more times.
path1**?**	ZeroOrOnePath	Connects the subject and object of the path by zero or one matches of path1, i.e., path1 is optional.
(path)	N/A	Specifies groups of paths. Use parentheses around groups to control precedence.
**!**URI
or
!(URI1	...	URIn)
**!^**URI
or
!(^URI1	...	^URIn)
You can include a combination of forward and reverse properties in a negated property set: !(URI1	...	URIj
