Hello,
I'm pleased to announce the first release of tmproc, a Topic Map
processor. This release is meant to be a technology preview.
Enjoy!

>>> What is tmproc?
tmproc is an implementation of the new international standard ISO/IEC
13250 Topic Maps[4]. tmproc is written in Python, and it should work
on any platform to which Python have been ported[2].
tmproc is a set of classes that represents a framework for doing topic
map processing in Python.
The current release includes the following set of classes:
o classes for representing topic map objects like TopicMap, Topic,
TopicName, Occurrence, Locator, Association, AssociationRole, Facet
and FacetValue.
o a factory class for creating topic map objects.
o a class for importing topic maps, TMImporter. It listens to SAX
events and use a factory class and interfaces to build a Topic Map.
o an export class, TMExporter, that emits SAX events in the topic map
interchange format so that any SAX document handler may be used for
export.
o statistical and information printing classes, TMUtils and TMStats.
A command line utility is also included in the distribution.
The implementation is currently based on a draft released some time
before the final ballot. Some deviations from the - soon to be
released - final standard is expected.
Currently only a in-memory implementation is available. A relational
database implementation have also been written, but is not available
in the distribution because it is a bit crude at the moment.
Fortunately tmproc has been written in a way that makes it easy to do
additional implementations.

>>> Some of the features are:
o Import, export, query and manipulation of topic maps.
o Full set of extensible topic map classes with clearly defined
interfaces. Association, AssociationRole, Facet, FacetValue, Locator,
Occurrence, Topic, TopicMap, TopicMapFactory and TopicName.
o Access to data in topic map objects using getter and setter methods.
o Get types including transitive types of topics, associations and facets.
o Get objects [e.g. topics, associations and facets] that are of
given types or more specific types.
o Get objects [e.g. associations] that exists in a scope or in any of
the scopes' subscopes.
o Optional architectural processing [requires xmlarch].
o Introduction and reference documentation.
