Global variables are often a bad idea. However, the majority of cwm
applications involve just one RDF store. One store can contain many
formulae. The main thing which these formulae of the same store share
is the index with which names and strings are interned. Within a
store, you can compare things by comparing memory addresses rather
than the whole tring, uri or list.
Therefore, it is normal to just use one store. When you do this, the
store paremeter to most methods beceomes unnecessary, and you get a
simpler API. That is what this module does. If you import it, you
will get a global store. This will not stop you using other stores.
You also get the Namespace() class which allows you to generate

undo what I did last thing Friday. Those changes are nowhere near ready for the trunk
Revision 1.9 2004/07/29 16:16:11 syosi
rdflib tests in the default test suite
Revision 1.8 2004/04/19 13:32:22 connolly
trap __special_names__ in Namespace.__getattr__ so
that pychecker can work
Revision 1.7 2004/03/21 04:24:35 timbl
on xml output, nodeID was incorrectly spelled.
update.py provides cwm's --patch option.
diff.py as independent progrem generates patch files for cwm --patch
Revision 1.6 2004/03/09 23:55:50 connolly
updated load to track change in llyn

See http://www.w3.org/2000/10/swap/doc/changes.html for details
- Regresssion test incorporates the RDF Core Positive Parser Tests except XMLLiteral & reification
- xml:base support was added in the parser.
- Use the --rdf=R flag to allow RDF to be parsed even when there is no enveloping <rdf:RDF> tag
- nodeid generated on RDF output
- Automatically generated terms with no URIs sort after anything which has a URI.
- Namespace prefix smarts on output - default ns used for that most frequently used.
- suppresses namespace prefix declarations which are not actually needed in the output.
- Cwm will also make up prefixes when it needs them for a namespace, and none of the input data uses one.-
- Will not use namespace names for URIs which do not have a "#". Including a "/" in the flags overrides.

Revision 1.3 2004/01/28 23:03:00 connolly

- wrapped some comments at 79 chars
