swish (hackage): 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 are given in the https://gitlab.com/dburke/swish/raw/master/CHANGELOG file.
