Maybe an XML pickler (http://www.gnosis.cx/download/Gnosis_Utils.More/Gnosis_Utils-1.2.1.ANNOUNCE untested by me). You might also use a JSON/YAML pickler. JSON is now a subset of YAML: http://cheeseshop.python.org/pypi/python-json/3.4 http://pyyaml.org/wiki/PyYAML http://jyaml.sourceforge.net/ http://www.yaml.org/ http://www.json.org/ http://www.json.org/java/
