TemaTres is an open-source, web-based thesaurus management package. Features include a simple, functional user interface for editing and browsing keywords, sophisticated search capabilities, and the ability to import or export all or part of the thesaurus in a number of standardized forms. TemaTres features a rich set of web services that provide searching and retrieval capabilities for external programs. As a result a number of tools such as "Visual Vocabulary," "ThesaurusWebPublishers" and "TemaTres View" use TemaTres as their backend. There are also capabilities for linking vocabularies in different languages to facilitate the creation of multilingual controlled vocabularies.
(TemaTres is developed in Argentina, and consequently not all documentation is available in English.)
