		| Abstract: | 
		The Unified Astronomy Thesaurus (UAT) is an open, interoperable and
 community-supported thesaurus which unifies the existing divergent and
 isolated Astronomy & Astrophysics vocabularies into a single
 high-quality, freely-available open thesaurus formalizing astronomical
 concepts and their inter-relationships.  The UAT builds upon the
 existing IAU Thesaurus with major contributions from the astronomy
 portions of the thesauri developed by the Institute of Physics
 Publishing, the American Institute of Physics, and SPIE.  We describe
 the effort behind the creation of the UAT and the process through which
 we plan to maintain the document updated through broad community
 participation. |
