--------
Overview
--------
The advent of SPARQL 1.1 introduced property paths as a new graph matching paradigm that allows the employment of Kleene star * (and it's variant +) unary operators to build SPARQL queries that are agnostic of the underlying RDF graph structure. The ability to express path patterns that are agnostic of the underlying graph structure is certainly a step forward. Still though, it is impossible to retrieve the actual paths through a property path sparql query. In this challenge, we ask for a system capable of returning the actual paths between two URIs in a RDF graph ranked by their length. This is of evident interest for big data approaches, because it enlarges the scope for picking up tuples / data while concurrently establishing a route between them that may be interpreted in different ways.
