Varve.Sparql

SPARQL 1.1 Query and Update as an immutable algebra, with SPARQL 1.2's additions present and marked, a parser from text to the algebra, and a serialiser back.

  • One tree. The parser produces the algebra of SPARQL 1.1 §18.2 directly: Join, LeftJoin, Filter, Extend, Group, Project, … as sealed records with value equality and a source span on every node.
  • SPARQL 1.2 from the start: triple terms, reified triples and annotation syntax expanded as §4.3 prescribes, VERSION, and the new functions. A caller asks for 1.1, 1.2-basic or 1.2; a VERSION declaration in the text narrows and never widens.
  • Round trip. SparqlWriter writes text that parses back to the identical tree, and a property test over generated algebra holds it to that.
  • Errors carry byte offset, line and column, and name what was expected. The first error ends the parse: a query is one unit.
  • Rewriting without reflection. AlgebraRewriter has one virtual method per node type; an optimiser is a rewriter, and so is a linter.
Query query = SparqlParser.ParseQuery("SELECT ?s WHERE { ?s a ?type }"u8);
string text = SparqlWriter.ToText(query);
