This module makes it possible to import and export vocabularies and taxonomy terms via XML, CSV, RDF and other formats.

If you want to just import a flat list of terms, or terms structured in various columns to represent heirarchy, Taxonomy CSV offers a number of CSV-style formats and the ability to just paste the list straight in. Try that for simpler jobs. CSV support in taxonomy_xml is limited to a specific (ISO 2788 - triples) format

Work is currently being done in the Drupal 6 branch to extend support for remote services - online vocabulary, glossary, thesaurus and taxonomy resources - so libraries of structured terms can be imported directly.
Examples include taxonomy structures of:

  • Hierarchical Countries and states
  • The Dewey Decimal system
  • Library of Congress classification scheme
  • IPTC press topic catalog
  • Encyclopedia of Life organism database

A goal is to get the taxonomy import/export to a point where a Drupal site can become a taxonomy server of its own, providing realtime vocabulary sharing.

Background on recent motivations that have moved this forward a bit.

Documentation distributed with the module includes:

PHP4 is no longer supported in the dev branch. Old compatibility code is being removed. PHP4 just doesn't do XML very well.
