The system checks its working memory to see if there are rules whose pre-conditions are satisfied, if so, the action in one selected satisfied rule is executed. There is a public domain implementation of an OPS5 interpreter written by Charles L. Forgy <[email protected]> in 1977. It was first implemented in Lisp and later in BLISS. It was also ported to Common Lisp by George Wood and Jim Kowalski. See also C5, OPS83, OPS4, OPS5+, OPS83. Inference Engine Tech, Cambridge MA.

  • pop3 — (messaging, protocol)   Version 3 of the Post Office Protocol. POP3 is defined in RFC 1081, written in November 1988 by Marshall Rose, which is based on RFC 918 (since revised as RFC 937). POP3 allows a client computer to retrieve electronic mail from a POP3 server via a (temporary) TCP/IP or other[?] connection. It does not provide for sending mail, which is assumed to be done via SMTP or some other method. POP is useful for computers, e.g. mobile or home computers, without a permanent network connection which therefore require a "post office" (the POP server) to hold their mail until they can retrieve it. Although similar in form to the original POP proposed for the Internet community, POP3 is similar in spirit to the ideas investigated by the MZnet project at the University of California, Irvine, and is incompatible with earlier versions of POP. Substantial work was done on examining POP in a PC-based environment. This work, which resulted in additional functionality in this protocol, was performed by the ACIS Networking Systems Group at Stanford University. RFC 1082 (POP3 Extended Service) extends POP3 to deal with accessing mailboxes for mailing lists.
