Change history |
|||
|
2000/05/25 |
Initial draft |
||
|
2000/06/16 |
Updated the DTD to resolve some ambiguities and updated example accordingly. Replaced href attribute with value. Modified the AID object semantics in order to permit the name field to contain a URL and to clearly specify the name of the user-defined properties. |
||
|
2000/06/19 |
Added a notes appendix temporarily to keep track of issues related to the specification. Minor phrasing edits. |
||
|
2000/06/21 |
Modified the semantics of user-defined for AID level and top level. Updated DTD and examples. |
||
|
2000/06/29 |
Made use of user defined parameters more clear; changed a-id to agent-identifier; changed a-id-user-defined to aid-user-defined |
||
|
2000/07/21 |
Changed the names of content-* parameters to be consistent with 00067 specification. Change envelope-to and –from to “to” and “from”. Deleted Section 2.2. on lexical analysis . Removed user-defined elements in envelope (user may define a new tag instead) and in the AID (now unsupported). Removed transport behaviour sub-elements (transport-errors etc.) which are not supported in other syntaxes. Relative time removed for consistency with other specifications |
||
|
2000/08/16 |
Changed the url and name tags from attribute to start/end form. Added specification for the envelope MIME type and on the body / envelope separation. Added some more references. |

Foreword
The Foundation for Intelligent
Physical Agents (FIPA) is an international organisation 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
organisations, 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 organisation 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.

specifications and upcoming meetings may be found at http://www.fipa.org/.
4 Informative Annex A – Examples
This document is part
of the FIPA specifications and deals with message transportation between
inter-operating agents. This document also forms part of the FIPA Agent
Management Specification [FIPA00023] and contains specifications for:
·
Syntactic representation
of a message envelope in XML form (see [W3Cxml]).
This section gives the concrete syntax for the message envelope specification that must be used to transport messages over a Message Transport Protocol (MTP - see [FIPA00067]). This concrete syntax is designed to complement [FIPA00071] and [FIPA00084].
The name assigned to
this component is:
fipa.mts.env.rep.xml.std
Where required, the MIME type (see [RFC2046] of items generated according to this specification is taken to be application/xml. The charset encoding used in this section must conform to [W3Cxml].
The
following DTD specifies the encoding of the abstract FIPA specification as an
XML message:
