The swish package

Swish is a framework, written in the purely functional programming language Haskell, 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.

Changes in version 0.9.0.2:

Updated the upper bound on the polyparse dependency.

Changes in version 0.9.0.1:

Updated the upper bound on the semigroup dependency (thanks to Leif Warner).

Changes in version 0.9.0.0:

Updated to support hashable-1.2 series; although this should *not* change the API from the 0.8 series, I have decided to bump up the version to 0.9 just in case.
Fix failing test on 64-bit GHC (no change to the library).
