It describes properties of the involved entities that are relevant to the particular observation. constraint An object or process that has a role in an observation. An Entity may play one of the following roles: ObjectOfInterest, ContextObject, Matrix. Whether the involvement of a particular entity is meaningful enough to include in the variable description depends on the specific context. entity A type of a characteristic of the ObjectOfInterest. property 1 1 A description of something observed or derived, minimally consisting of an ObjectOfInterest and its Property. variable
