3.1.1

WARNING this issue introduced a problem with Array#dup and has been yanked. Use the 3.1.2 version.

Significate updates:

  • Support for query optimization

  • Provisional support for SPARQL*.

  • When grouping solutions, don't create a solution if there are any expressions, otherwise (not grouping), return a single solution binding aggregated variables.

    The principle is that "aggregate, no group-by => one row always", "aggregate, with group-by => same number of rows as the group-by" for empty and no-empty matching.

    See w3c/rdf-tests#61

  • SPARQL*

    • Parses SPARQL* expressions.
    • In Algebra::Extend, bind the solution to the value if the value is a pattern.
    • Define result formats when solutions have embedded triples (based on RDF4J).

  • Query optimization:

    • Implement query optimization (such as it is) and run optimized queries when running specs.
    • Update method signature of #optimize and #optimize! with **options to be compatible with that from RDF::Query.
