This directory contains some software available from this site.
- Mail message parsing and handling in Python.
Includes my First Python Program: a program to traverse Eudora mailboxes and
generate XML/RDF compatible output from them.
- Feature set matching, according to RFC
2533. Java source code and test programs. Software classes are defined
to parse feature expressions from reader streams, and perform matching on
them. See the test programs for examples. There is currently no command-line
or GUI version of the software, but it should be easy enough to implement.
- RDF report generator. This ZIP file includes Python source code for an N3 parser (by now a dated version of N3 syntax), N3 data access and N3 report generator, as described in RDF for "Little Languages". Updated 07-May-2002, to accept (questionable) cwm output. Updated 9-May-2002 to dramatically improve performance. Updated 10-May-2002 with improved formatting of author information. Updated 24-May-2002 with various enhancements and bug-fixes, added Jython and Jena interface modules. Updated 5-Jun-2002 with options to trim spaces from formatted values. Updated 16-Sep-2002 with document issue report generator module, and bug-fix to N3 parser handling of triple-quoted strings. Updated 19-Sep-2002: report generator to scan containers and lists; updated list vocabulary to use new RDF terms; report generator capability to display local part of URI; document issue formatter to handle document and issue histories. Updated 21-Oct-2002 to support protocol cross reference utility; added first- and last- options to repeated pattern processing, so simplifying output generation. Updated 12-Dec-2002 to add a general-porpose report generator program (N3GenReport.py) that reads a report generator template from an external .n3 file.
- Python-to-Jena interfacing. I've been experimenting with using Jython (version 2.1) to interface my Python code to a Jena RDF model store. This software allows Python programs to load and access a Jena model. The Python code that I have running under Jython to access the Jena model is in N3ModelJena.zip. This version contains code to access memory- or RDB-based Jena models from Python.
- One of the modules is a modified version of the Jython javaos.py module with an implementation of Python's os.access() method.
- I've found it convenient to make some small modifications to Jena, viz adding isResource() and isLiteral() methods to the RDFNode interface - the code is in JenaRDFNodeSrcMods.zip. (I couldn't figure how to get Jython to do a class type enquiry on a Java object.)
- The Jython.bat file is also modified to include Jena libraries on the class path -- this is included for information and will almost certainly need to be modified for any environment other than mine.)
- Updated 15-May-2002 to add Jena RDB-based model support.
- URI parsing and handling in Haskell. Released: 5-Mar-2003. [ZIP archive, Read me file].
- Swish: a Semantic Web Inference Skeleton in Haskell, V0.2 released 20-Dec-2003. [Home page, ZIP archive, description].
- (Also, some random notes related to my experience of learning Haskell, coming to it from long experience of using non-functional programming languages.)
- FatHugs, a build of the Hugs for Microsoft Windows, based on the 20040109 source snapshot, with increased character range support (for Unicode) and the code storage area enlarged to accommodate larger programs. [Description page, EXE file, ZIP file]. Also, a sorresponding version of RunHugs [EXE file, ZIP file].
- HaskellUtils, a collection of general purpose Haskell library source files (and test modules).
- Haskell URI handling code. A new implentation, proposed as a replacement for the Haskell Network.URI module, with test cases. This implementation is based closely on the revised RFC2396 specification, modulo some issues under discussion on the URI mailing list. Work-in-progress, 20 Feb 2004.
