Foreword
The Foundation for Intelligent Physical Agents
(FIPA) is an international organization that is dedicated to promoting the
industry of intelligent agents by openly developing specifications supporting
interoperability among agents and agent-based applications. This occurs through
open collaboration among its member organizations, which are companies and
universities that are active in the field of agents. FIPA makes the results of
its activities available to all interested parties and intends to contribute
its results to the appropriate formal standards bodies.
The members of FIPA are individually and
collectively committed to open competition in the development of agent-based
applications, services and equipment. Membership in FIPA is open to any
corporation and individual firm, partnership, governmental body or
international organization without restriction. In particular, members are not
bound to implement or use specific agent-based standards, recommendations and
FIPA specifications by virtue of their participation in FIPA.
The FIPA specifications are developed through
direct involvement of the FIPA membership. The status of a specification can be
either Preliminary, Experimental, Standard, Deprecated or Obsolete. More detail about the process of
specification may be found in the FIPA Procedures for Technical Work. A
complete overview of the FIPA specifications and their current status may be
found in the FIPA List of Specifications. A list of terms and abbreviations
used in the FIPA specifications may be found in the FIPA Glossary.
FIPA is a non-profit association registered in
Geneva, Switzerland. As of January 2000, the 56 members of FIPA represented 17 countries worldwide. Further information
about FIPA as an organization, membership information, FIPA specifications and
upcoming meetings may be found at http://www.fipa.org/.
