Package: swish (0.10.9.0-2 and others)

semantic web toolkit - tools

Swish is a framework for performing deductions in RDF data using a variety of techniques. Swish is conceived as a toolkit for experimenting with RDF inference, and for implementing stand-alone RDF file processors (usable in similar style to CWM, but with a view to being extensible in declarative style through added Haskell function and data value declarations). It explores Haskell as "a scripting language for the Semantic Web".

Swish is a work-in-progress, and currently incorporates:

 * Turtle, Notation3 and NTriples input and output.
   The N3 support is incomplete (no handling of @forAll).
 * RDF graph isomorphism testing and merging.
 * Display of differences between RDF graphs.
 * Inference operations in forward chaining, backward chaining
   and proof-checking modes.
 * Simple Horn-style rule implementations,
   extendable through variable binding modifiers and filters.
 * Class restriction rule implementation,
   primarily for datatype inferences.
 * RDF formal semantics entailment rule implementation.
 * Complete, ready-to-run, command-line and script-driven programs.

This package provides the command-line tool Swish.
