Abstract: On March 14–15, 2006, at the US National Institute of Standards and Technology (NIST) in Gaithersburg, MD, there took place the first Upper Ontology Summit (UOS). This was a convening of custodians of several prominent upper ontologies, key technology participants, and interested other parties, with the purpose of finding a means to relate the different ontologies to each other. The result is reflected in a joint communiqué, directed to the larger ontology community and the general public, and expressing a joint intent to build bridges among the existing upper ontologies in ways designed to increase and rationalize their utilization and to enhance their semantic interoperability. The Upper Ontology Summit was sponsored by NIST, Ontolog, the National Center for Ontological Research (NCOR), MITRE, and many other organizations. The UOS was organized by a committee consisting of Pat Cassidy, Peter Yim, Steve Ray, Dagobert Soergel, and Leo Obrst.
