Template: OASIS:EnvironmentDefinition

This section specifies the template EnvironmentDefinition.

The specification comprises a SysML Block that represents the template and an associated Parametric Diagram that defines the templates and PLCS PSMTemplate objects instantiated by the EnvironmentDefinition template.

The specification comprises the following sections:

NOTE    An explanation of a template and its specification is provided in the Template overview

The EnvironmentDefinition template describes how to represent a typical environment. A typical environment is an identified managed object. A set of properties are associated to the typical environment providing a definition of the typical environmental characteristics such as temperature and humidity that characterize the environment.

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

Figure 1 -  Environment model

No templates have been explicitly defined as being related to the EnvironmentDefinition template.

NOTE    The EnvironmentDefinition template may make reference to other templates as part of the Parametric Diagram. These are not listed here.

Figure 2 shows the SysML Block that represents the template. The Block is an abstraction representing a pattern of templates and PLCS PSMTemplate objects.

The properties, i.e. the SysML Block Part, Reference and Value properties, of the template's SysML Block are described in the Template Properties section.

The output ports shown on the template's SysML Block are described in the template output ports section.

The SysML Parametric diagrams for the template Block are shown in template parametric diagram section.

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

References:
viewDefinitionContext [1] (Template: OASIS:ViewDefinitionContext)
The ViewDefinitionContext for the typical environment (EnvironmentDefinitionView)
properties [0..*] (Block: Ap239Ap233Psm:PropertyValue)
The collection of property values`(PropertyValue) providing a definition of the typical environmental characteristics. (i.e. Temperature ranges, etc ...)
definition [1] (Block: Ap239Ap233Psm:ProxyItemSelect)
The reference data that identifies the environment definition.
The reference data that identifies the environment definition.
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:
Parts:
descriptions [0..*] (Template: OASIS:Descriptor)
The collection of descriptions of the typical environment (EnvironmentDefinition)
names [0..*] (Template: OASIS:Name)
The collection of names of the typical environment (EnvironmentDefinition)
classifications [0..*] (Template: OASIS:Classifier)
The collection of classifications for the typical environment (EnvironmentDefinition)
The reference data used in Template: OASIS:Classifier is restricted as follows:
RDL constraint 1:
The reference data for:
OASIS:Classifier.class -> ExternalOwlClass.class
is restricted to classes that are subclasses of the following class:

The following output ports are defined for this template:

envDef (Block: Ap239Ap233Psm:EnvironmentDefinition)
Enables the Block: Ap239Ap233Psm:EnvironmentDefinition instantiated by this template to be referenced when the template is used.
envDef_vn (Block: Ap239Ap233Psm:EnvironmentDefinitionVersion)
Enables the Block: Ap239Ap233Psm:EnvironmentDefinitionVersion instantiated by this template to be referenced when the template is used.
envDef_view (Block: Ap239Ap233Psm:EnvironmentDefinitionView)
Enables the Block: Ap239Ap233Psm:EnvironmentDefinitionView instantiated by this template to be referenced when the template is used.

There are no constraints defined for this template.

This section describes the template's Parametric Diagram. The diagram details the pattern of templates and PLCS PSMTemplate objects that are required to represent the template EnvironmentDefinition.

The public properties, i.e. those visible in the template's SysML block (See Figure 2) are shown on the left of a Parametric Diagram.

NOTE    Restrictions on the reference data to be set on the public properties is defined in the Template Properties section.

The output ports are shown on the right of a Parametric Diagram.

PLCS PSM objects are shaded khaki and Templates are shaded light green in a Parametric Diagram.

The following blocks are instantiated by this template and bound to private parts of the template as shown in the Parametric Diagram section:

Private Part Property:ed [1] (Block: Ap239Ap233Psm:EnvironmentDefinition)
Private Part Property:edv [1] (Block: Ap239Ap233Psm:EnvironmentDefinitionVersion)
Private Part Property:edview [1] (Block: Ap239Ap233Psm:EnvironmentDefinitionView)
Private Part Property:pva [0..1] (Block: Ap239Ap233Psm:PropertyValueAssignment)
Private Part Property:proxyItem [1] (Template: OASIS:ProxyItem)
Private Part Property:combNameAndDesc [1] (Constraint Block: OASIS:Name:CombineNamesAndDescriptors)

Figure 3 shows the instances that have been instantiated in the template. These are used to set the default value of blocks.
