Hello, I'm pleased to announce the second release of GPS - Groves and Property Sets for Python. There has been a lot of changes in this release. The most important being the support for grove managers and managed grove nodes, and a grove walker module. See the changes.txt file in the distribution for a complete list of changes. Suggestions and bug reports should be sent to: grove@infotek.no Geir O. Grønmo -------------------------------------------------------------------------- Title: GPS - Groves and Property Sets for Python Version: 0.20 Released: November 12th 1999 Author: Geir O.

What is GPS?

GPS is an implementation of the groves and property set concepts defined in the HyTime and DSSSL standards. GPS is written in Python, and should work* on any platform to which Python have been ported - including the Java Platform. There are two implementations in the current distribution, one in-memory implemention and one that supports ZODB - the Zope Object Database. Both groves, property sets and grove plans can be made persistent by the ZODB implementation. - --

Features

o Loading of property sets from documents conforming to the Property Set DTD, or any derived DTD [requires architectural processing]. o Grove plans. Default grove plans is automatically created by wrapping a GrovePlan object around a property set. Inclusion and omitting of modules, classes and properties are fully supported. o Self-managed and managed grove node implementations, both generic classes for representing grove nodes. o Grove managers that manages a repository of managed grove nodes. o ZODB - Zope Object Database versions of all grove, grove manager, property set and grove plan classes, plus some ZODB utilities. o Module for building XML groves from SAX event streams. This module also contains a class for emitting SAX events by walking XML groves. o Grove walkers, allows for selective processing of groves. o Sample Property Sets - --

Requirements

- Python 1.5.2 or newer [3] - An SGML/XML parser with a SAX driver - SAX 1.0 for Python [4] - xmlarch 0.25, optional unless architectural processing is needed [5] - --
