This first phase is mainly a platform for future development, consisting of:
- A data types and functions for manipulating RDF models,
with a simple interface for creating, combining, accessing and
comparing RDF graphs
- A Notation3 parser. Notation3 is an alternative syntax for RDF, easier
than RDF/XML: for some purposes. For information, see:
http://www.w3.org/DesignIssues/Notation3.html
http://www.w3.org/2000/10/swap/doc/
- A basic Notation3 formatter
- A command-line utility for testing the above
- Numerous test programsThe code's a bit tacky (by Haskell standards) but it does seem to work pretty reliably. It has been tested with the Hugs and GHC Haskell systems.
As it stands, it doesn't do much other than testing for RDF graph structural equivalence and merging graphs (renaming nodes as needed to "free variable" type conflicts). I'm currently working on designing some modules for doing simple queries and inferences on the RDF data.
