KQML

Knowledge Query and Manipulation Language

An agent specification language. A language and protocol for exchanging information and knowledge. KQML is part of the ARPA Knowledge Sharing Effort for building sharable, reusable large-scale knowledge bases. KQML is both a message format and a message-handling protocol to support run-time knowledge sharing among agents. KQML can be used as a language for an application program to interact with an intelligent system or for two or more intelligent systems to share knowledge in support of cooperative problem solving.
