UNKNOWN public static final int UNKNOWN constant identifying an unknown performative The performative parameter denotes the type of the communicative act of the ACL message as defied by FIPA00037. Note: The performative parameter is a required parameter of all ACL messages.

All parameters are couples keyword: value. In this paper, we arrange FIPA's ACL performatives to form a sub-sumption lattice (ontology) and apply a theory of social commitments to achieve a simplified and observable model of agent behaviour.

Content A proposition. 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 Document Policy [f-out-00000] and the FIPA Specifications Policy [f-out-00003] .

In the latter case (the FIPA-ACL way), the achieve performative is pushed into the content language, thus eliminating the need for the same in the ACL. KQML VS FIPA ACL PERFORMATIVES KQML Performative Equivalent FIPA Performative Ask-if Query-if Deny Inform or disconfirm Insert, uninsert Inform, FIPA ACL Performatives Negotiation accept-proposal sender accepts proposal made by other agent cfp call for proposals; initiates negotiation between agents; content-parameter contains action (desired to be done by some other agent) (e.g.: „sell me car“) and condition (e.g.: „price < 1000$“) reject-proposal sender does not accept proposal The foundational features of multi-agent systems are communication and interaction with other agents. To achieve these features, agents have to transfer messages in the predefined In FIPA ACL there are some performatives, such as proposal, CFP and so on, for general agent negotiation processes, but they are not sufficient for our purposes. performatives and prot ocols of FIPA’97 ACL from th is point of view.

Parameters: performative - An integer identifying the FIPA performative to be set to this FIPA performatives provide an outline for the existence and action of agents. Existing FIPA protocols have been described through Petri-nets but the timing aspect was not speciﬁed which was a limitation. The main idea of this research is to formally model the existing FIPA performatives by Timed Arc Petri-Nets (TAPNs) in real-time multi-agent 1.1 Performatives The FIPA standard SC00037J [9] deﬁnes 22 “Communicative Act” names as values for the performative ﬁeld (see Table 1). In implementing our agent infrastructure, CASA [13], we have found that the FIPA performatives were very useful in that they include communicative acts that we would not have initially thought of ourselves.

utterance of a performative, and of the receiver after the receipt and processing of a message. – Completion conditions - indicate the final state, after a conversation has taken place and the intention associated with the performative that started the conversation has been fulfilled. 4. 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.

accept_proposals (list): A list of 'accept_proposal' performative messages in the agent's mailbox; agrees (list): A list of 'agree' performative messages. Other extensions to the FIPA performatives include the addition of an ack (acknowledge) performative, which, in CASA, serves as an optional top-level method of checking receipt of messages. In this paper, we arrange FIPA's ACL performatives to form a sub-sumption lattice (ontology) and apply a theory of social commitments to achieve a simplified and observable model of agent behaviour. The FIPA standard is an agent oriented programming abstraction: A standard for defining heterogeneous and interacting agents. ACL is a widely adopted specification of the FIPA standard, based on speech act theory (J Searle, 1970).

For example, to reply a message with a 'request' performative message, the modeller should use the 'request' action. returns: unknown; message (message): The message to be replied inform FIPA performatives. The goal of both the tell KQML performative and the inform FIPA performatives is to convey to some receiving agent that the sending agent believes a particular proposition (contained in the content field of a performative) is true. Referring to Table 1, it can be seen that the syntax of the FIPA inform performative 5.2 FIPA ACL Message Structure FIPA ACL messages are standardized to ensure interoperability and to provide well-defined process.

FIPA is the specialist for vacuum technology, End-of-Arm-Tooling and lifting technology with a strong focus on plastics, sheet metal and packaging markets.

Its syntax is defined by performatives parameterised by attribute value pairs, while its semantics is given in terms of constant identifying the FIPA performative.
