Code Overview

llyn.py - The Store

An in-memory store which does the inference.

notation3.py - Serializing/deserializaing RDF

Originally written by Dan Connolly, uses a basic RDF stream parser interface

• Parses N3
• Generates N3

The command line form (alias n3 python notation3.py; n3 -help) allows RDF to be parsed and re-output.

The module will also run as a CGI script to convert N3 to RDF M&S 1.0 - by DanC magic.

• Source

xml2rdf.py Parsing RDF/XML

Based on Python's xmllib, this parser is compatible with the RDF stream interface of, notation3.py. It completes the square of parsers and generators. Defunct. Now use sax parser and sax2rdf.py.

• Parses RDF

It has a command line mode for self-test purposes.

• Source

cwm_xxx.py - builtin modules

These are quite easy to add to

Design issues

The code above investigated and raised issues discussed in the following documents.

• Notation 3 - an alternative RDF syntax
• Quantification implicit in anonymous nodes

not to mention

• RDFM&S and schema issues
• The question of quoting and BagIDs etc

Code Review notes

5Aug2002, DanC

• relative URI stuff is all over the map. move to uripath.py done, pretty much
• why is verbosity() in thing? that seems to be the only part of the thing module that llyn uses
• use Namespace() class; N3_forAll_URI = RDFSink.forAllSym -> log.forAll
• use subclasses of string, rather than pairs, for terms? (ala eikon's rdflib)
• python style:
  • would be nice to have module dependency graph, to know where to start scrubbing
  • scrub modules for python style; (cite the styleguide from scrubbed modules) benefit: nice pydoc
  • start using python's unit test stuff? maybe start with uripath.py
  • scrub with pychecker? (@@cf. earlier report mailed to www-archive)
  • is there a __debug__ or some other established convention to use in place of verbosity()?
• open source community style:
  • no README in cwm.tar.Z
  • no CHANGES in cwm.tar.Z
  • cwm.tar.Z: compress??? er... .tgz, please
• this file should be XHTML
