2. We have been using Protégé frame [2] for ontology construction in my courses too. Protégé is free and have a lot of plug-ins, including visualization. It could easily handle lightweight ontologies if we count good taxonomies and thesaurus in. You may use Protégé Frame’s functions partially for your thesaurus management and output. In terms of managing and keep the updating history, I think you can try some other extensions. One problem is that I do not think you can import a Z39.19 thesaurus into it. You have to really build one based on your original thesaurus.

We have an ANSI/NISO Z39.19 thesaurus of over 20,000 terms currently maintained in a very old proprietary database. At the moment the thesaurus is only available as human-readable HTML (a one off dump from the database) or dead trees. The thesaurus is recommended as a vocabulary encoding scheme for AGLS (an application profile of Dublin Core).
Can anybody recommend software (preferably open source) which can maintain a Z39.19 thesaurus (preferably in an open format) and export in a machine-readable format and published so individual terms can be a valid value URI?
