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/.

Representation Selection
This document is part of the FIPA specifications and deals with agent middleware to support applications in nomadic environment. This specification also forms part of the FIPA Nomadic Application Support Specification [FIPA00066] and contains specifications for:
· Ontological descriptions.
This section describes a set of frames, that represent the classes of objects in the domain of discourse within the framework of the FIPA-Nomadic-Application and FIPA-MTS-QoS ontologies.
The following terms are used to describe the objects of the domain:
· Frame. This is the mandatory name of this entity, that must be used to represent each instance of this class.
· Ontology. This is the name of the ontology, whose domain of discourse includes the parameters described in the table.
· Parameter. This is the mandatory name of a parameter of this frame.
· Description. This is a natural language description of the semantics of each parameter.
· Presence. This indicates whether each parameter is mandatory or optional.
· Type. This is the type of the values of the parameter: Integer, Word, String, URL, Term, Set or Sequence.
· Reserved Values. This is a list of FIPA-defined constants that can assume values for this parameter.
This type of object represents the quality of service of the transport protocol.
