KQML: a transport protocol for Querying and manipulating knowlwdge.
A KQML query specifies
1. a performative, that is an operation as ASK(=GET), TELL (=PUT), SUBSCRIBE, ADVERTISE, ... extensible <BR>
2.an ontology to partition the world of knowledge into terminological distinct domains (for Maintenance) i.e., tanks in the military, in gas stations, in cars, a refinery, ....3. the representation: objects (say per CORBA), rules (say per KIF), equations, database tuples, text (constrained or not by a domain ontology)...
Matchmaker speaks KQML to facilitate information transfer.
Expands simple communication to a brokered approach.
Benefits of matchmakers:
Locating unknown information sources
Enables having a flexible architecture.
Expressiveness of advertisements and requests
Persistence of requests
Consistency, efficiency, efficacy
Troubles due to
WWW for machine consumption.
