Date: 22 Mar 1999 08:48:22 -2300 From: Geir Ove Grønmo, email@example.com To: firstname.lastname@example.org Subject: ANN: tmproc 0.10, a Topic Map implementation
I'm pleased to announce the first release of tmproc, a Topic Map processor. This release is meant to be a technology preview.
Released: March 23rd 1999
Author: Geir O. Grønmo, email@example.com
- Python 1.5.1 or newer 
- An SGML/XML parser with a SAX driver
- SAX for Python 
- xmlarch 0.25, optional unless architectural processing is needed 
What is tmproc?
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:
classes for representing topic map objects like TopicMap, Topic, TopicName, Occurrence, Locator, Association, AssociationRole, Facet and FacetValue.
a factory class for creating topic map objects.
a class for importing topic maps, TMImporter. It listens to SAX events and use a factory class and interfaces to build a Topic Map.
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.
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:
Import, export, query and manipulation of topic maps.
Full set of extensible topic map classes with clearly defined interfaces. Association, AssociationRole, Facet, FacetValue, Locator, Occurrence, Topic, TopicMap, TopicMapFactory and TopicName.
Access to data in topic map objects using getter and setter methods.
Get types including transitive types of topics, associations and facets.
Get objects [e.g. topics, associations and facets] that are of given types or more specific types.
Get objects [e.g. associations] that exists in a scope or in any of the scopes' subscopes.
Optional architectural processing [requires xmlarch].
