Notes:
Understanding of terminology requires a shared vocabulary, or common ontology, to describe the concepts, relationships and jargon of various domains. Examples of message formats include EDIFACT and ANSI X12 for EDI, Knowledge Query and Manipulation Language (KQML) for knowledge sharing, and OAGIS messages for interaction of business applications. Before a unit can communicate, it must be able to locate the units(s) with which it wants to communicate, and decide the appropriate kind of communication. When received, a directive message incurs an obligation on the unit, which instantiates an appropriate process to fulfill the obligation when due.
