instrument
(instrument ?EVENT ?TOOL) means that ?TOOL is used by an agent in bringing about ?EVENT and that ?TOOL is not changed by ?EVENT. For example, the key is an instrument in the following proposition: The key opened the door. Note that instrument and resource cannot be satisfied by the same ordered pair.
Relationships      
Parents patient (patient ?PROCESS ?ENTITY) means that ?ENTITY is a participant in ?PROCESS that may be moved, said, experienced, etc. For example, the direct objects in the sentences 'The cat swallowed the canary' and 'Billy likes the beer' would be examples of patients. Note that the patient of a Process may or may not undergo structural change as a result of the Process. The CaseRole of patient is used when one wants to specify as broadly as possible the object of a Process.
Children computer running(computerRunning ?Process ?Computer) means that the ComputerProcess ?Process is running on ?Computer.
 conveyance(conveyance ?EVENT ?OBJ) means that ?OBJ is the Vehicle or other transportation device used in ?EVENT.
 eCommerceSiteThis CaseRole relates an instance of a FinancialTransaction to the WebSite that facilitaed the sale.
 reagent(reagent ?PROCESS ?SUBSTANCE) means that ?SUBSTANCE is a chemical agent in the chemical reaction ?PROCESS.
 standard error device(standardErrorDevice ?PROGRAM ?DEVICE) holds just in case the DEVICE is the predefined error channel with which the running version of this program is initialised.
 standard input device(standardInputDevice ?PROCESS ?DEVICE) holds just in case the DEVICE is the predefined input channel with which the running version of the program PROCESS is initialised.
 standard output device(standardOutputDevice ?PROGRAM ?DEVICE) holds just in case the DEVICE is the predefined output channel with which the running version of this program is initialised.
InstancesabstractProperties or qualities as distinguished from any particular embodiment of the properties/qualities in a physical medium. Instances of Abstract can be said to exist in the same sense as mathematical objects such as sets and relations, but they cannot exist at a particular place and time without some physical encoding or embodiment.
 antisymmetric relationBinaryRelation ?REL is an AntisymmetricRelation if for distinct ?INST1 and ?INST2, (?REL ?INST1 ?INST2) implies not (?REL ?INST2 ?INST1). In other words, for all ?INST1 and ?INST2, (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST1) imply that ?INST1 and ?INST2 are identical. Note that it is possible for an AntisymmetricRelation to be a ReflexiveRelation.
 asymmetric relationA BinaryRelation is asymmetric if and only if it is both an AntisymmetricRelation and an IrreflexiveRelation.
 binary predicateA Predicate relating two items - its valence is two.
 binary relationBinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
 case roleThe Class of Predicates relating the spatially distinguished parts of a Process. CaseRoles include, for example, the agent, patient or destination of an action, the flammable substance in a burning process, or the water that falls in rain.
 entityThe universal class of individuals. This is the root node of the ontology.
 inheritable relationThe class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
 irreflexive relationRelation ?REL is irreflexive iff (?REL ?INST ?INST) holds for no value of ?INST.
 partial valued relationA Relation is a PartialValuedRelation just in case it is not a TotalValuedRelation, i.e. just in case assigning values to every argument position except the last one does not necessarily mean that there is a value assignment for the last argument position. Note that, if a Relation is both a PartialValuedRelation and a SingleValuedRelation, then it is a partial function.
 predicateA Predicate is a sentence-forming Relation. Each tuple in the Relation is a finite, ordered sequence of objects. The fact that a particular tuple is an element of a Predicate is denoted by '(*predicate* arg_1 arg_2 .. arg_n)', where the arg_i are the objects so related. In the case of BinaryPredicates, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
 relationThe Class of relations. There are three kinds of Relation: Predicate, Function, and List. Predicates and Functions both denote sets of ordered n-tuples. The difference between these two Classes is that Predicates cover formula-forming operators, while Functions cover term-forming operators. A List, on the other hand, is a particular ordered n-tuple.
