FIPA (Foundation of Intelligent Physical Agents) Communicative Acts published Dec. 2003

Accept Proposal	The action of accepting a previously submitted proposal to perform an action.
Agree	The action of agreeing to perform some action, possibly in the future.
Cancel	The action of one agent informing another agent that the first agent no longer has the intention that the second agent performs some action.
Call for Proposal	The action of calling for proposals to perform a given action.
Confirm	The sender informs the receiver that a given proposition is true, where the receiver is known to be uncertain about the proposition.
Disconfirm	The sender informs the receiver that a given proposition is false, where the receiver is known to believe, or believe it likely that, the proposition is true.
Failure	The action of telling another agent that an action was attempted but the attempt failed.
Inform	The sender informs the receiver that a given proposition is true.
Inform If	A macro action for the agent of the action to inform the recipient whether or not a proposition is true.
Inform Ref	A macro action for sender to inform the receiver the object which corresponds to a descriptor, for example, a name.
Not Understood	The sender of the act (for example, i) informs the receiver (for example, j) that it perceived that j performed some action, but that i did not understand what j just did.
Propagate	The sender intends that the receiver treat the embedded message as sent directly to the receiver, and wants the receiver to identify the agents denoted by the given descriptor and send the received propagate message to them.
Propose	The action of submitting a proposal to perform a certain action, given certain preconditions.
Proxy	The sender wants the receiver to select target agents denoted by a given description and to send an embedded message to them.
Query If	The action of asking another agent whether or not a given proposition is true.
Query Ref	The action of asking another agent for the object referred to by a referential expression.
Refuse	The action of refusing to perform a given action, and explaining the reason for the refusal.
Reject Proposal	The action of rejecting a proposal to perform some action during a negotiation.
Request	The sender requests the receiver to perform some action.
Request When	The sender wants the receiver to perform some action when some given proposition becomes true.
Request Whenever	The sender wants the receiver to perform some action as soon as some proposition becomes true and thereafter each time the proposition becomes true again.

The underlying assumption is that this is a complete set of performatives to describe all agent communication. I believe it was originally based on earlier work on KQML.  Are these the atomic building blocks of interactions? How does this map to the dimensions proposed by Mehta?
