Template:- OASIS:StateAssertion

This template describes how to represent the fact that something has been observed to be in a given state and that this assertion has been confirmed by evidence such as a measurement.

NOTE    An asserted state should be used for representing business process states such as Approval and work order states.

For details on how represent a hypothesized state, see StateAssessment.

The asserted state is assigned by a AppliedStateAssignment. This is not instantiated by this template, but is needed to assign the observed state to something. When assigning the state, the role of the AppliedStateAssignment should be specified by being classified. For example, if the sate observed is a fault state then the AppliedStateAssignment should be classified by as a http://docs.oasis-open.org/plcs/ns/plcslib/v1.0/data/contexts/OASIS/refdata/plcs-rdl#Fault_state_assignment.

The SysML Block Definition diagram in Figure 1 shows how State is represented in the PLCS PSM.

Template Properties

The following Part, Reference, and Value properties are defined for this template:

Parts:
definition [1] (Block: Ap239Ap233Psm:ProxyItemSelect)
The reference data that identifies the state definition that the observed state is asserted to be in.
The reference data used in Block: Ap239Ap233Psm:ProxyItemSelect is restricted as follows:
RDL constraint 1:
The reference data for:
ExternalOwlObject.individual
is restricted to individuals that are members of the following class:
http://docs.oasis-open.org/plcs/ns/plcslib/v1.0/data/plcs/plcs-psm/refdata/plcs-psm#StateDefinition
id [0..1] (Template: OASIS:Identification)
An optional identification of the observed state.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The id must be classified as a state definition identification code.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
http://docs.oasis-open.org/plcs/ns/plcslib/v1.0/data/contexts/OASIS/refdata/plcs-rdl#State_definition_identification_code
description [0..1] (Template: OASIS:Descriptor)
An optional description of the observed state.
observedBy [0..*] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationSelect)
the person or organization that observed the state.
Values:
assertionDateTime [0..1] (Block: Ap239Ap233Psm:DateTimeString)

The date or dateTime when the observed state was asserted to be a defined state.

NOTE    The assertionDateTime and the observationDateTime may be the same
observationDateTime [0..1] (Block: Ap239Ap233Psm:DateTimeString)
The date or dateTime when the state was observed.
