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 0.9.0.5:
Turtle/N3 output: more changes for string literals containing double-quote characters.
N3 Parser: parsing of string literals within three quote marks has been updated to match the Turtle parser.
Turtle Parser: a few more error messages have been added.
Changes in version 0.9.0.4:
Turtle parser: updated to the Candidate Recommendation (19 February 2013) specification; added minor improvements to error messages when given invalid syntax. As part of the upgrade, there is no longer a default namespace set up for the empty prefix and numeric literals are no-longer converted into a canonical form.
Turtle/N3 output: improved string formatting (better handling of string literals with three or more consecutive " characters); blank node handling has been improved but the output may not be as elegant.
NTriples parser: now accepts upper-case language tags such as en-UK (case is preserved).
Swish.QName.LName names can now contain #, : and / characters.
Added tests for the Turtle parser and formatter.
The new w3ctests flag will build the runw3ctests executable, which will run the W3C Turtle tests (if downloaded from http://www.w3.org/2013/TurtleTests/).
Minor fixes and additions to the documentation.
Changes in version 0.9.0.3:
Minor Haddock fix to Swish.RDF.Parser.Utils.appendURIs.
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).
