Summary notice about using this online contribution form

The Art & Architecture Thesaurus® (AAT), Getty Thesaurus of Geographic Names® (TGN), and Union List of Artist Names® (ULAN) are each a compilation of data from various contributors and various sources. They are supplemented and updated based upon contributions from contributing institutions. The databases are licensed to various institutions, companies, and individuals.

Only data that contains all required fields, complies with the Editorial Guidelines, and is within scope for the vocabulary will be published. The Vocabulary Program will incorporate contributed data that meets these criteria into the merged format of the vocabulary and cite the contributing institution as the source for names/terms that it has contributed.

By contributing data to the vocabulary, the contributor agrees to its contributed data becoming a permanent part of the Art & Architecture Thesaurus®, Getty Thesaurus of Geographic Names®, or Union List of Artist Names®, and grants a perpetual, royalty-free license to use the data.

The Getty Vocabulary Program maintains the right to final editorial control over the vocabularies, and reserves the right to refuse data contributions that do not follow the prescribed guidelines and format, are outside the scope of the vocabulary, or otherwise inappropriate for the vocabulary.

By contributing data, the contributor warrants that the contributed data does not infringe any proprietary rights or any statutory copyright, and that contributed material is not offensive or defamatory.

The Getty Vocabulary Program maintains copyright to the compilation of data in the Art & Architecture Thesaurus®, Getty Thesaurus of Geographic Names®, and Union List of Artist Names®.

Below is the full agreement for contributions:
