twinql
twinql is a parser and query engine for the SPARQL RDF query language, built on the Wilbur Semantic Web toolkit for Common Lisp. It is capable of the following:
  • Running SPARQL queries against a Wilbur database
  • Parsing of the SPARQL SQL-like syntax into an intermediate s-expression format
  • Resolution of query patterns into results tables, which are accessible as lists of hashes for programmatic manipulation
  • Output of result lists in human-readable format and in the SPARQL XML query result format
  • Evaluation of SELECT, ASK, CONSTRUCT, and DESCRIBE queries (the latter returning unions of CBDs).
