Template: OASIS:EnvironmentObserved

This section specifies the template EnvironmentObserved.

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 EnvironmentObserved template.

The specification comprises the following sections:

• Section Description provides a description of the template;
• Section Template Block specifies the SysML Block that represents the template;
• Section Template Properties specifies the properties, i.e. the SysML Part, Reference and Value properties of the templates SysML Block;
• Section Template Output Ports specifies the SysML Output Ports of the templates SysML Block. These bind to the templates and PLCS PSM objects instantiated by the EnvironmentObserved template as described in section Template Parametric Diagram;
• Section Template Constraints specifies the constraints on PLCS PSMTemplate objects instantiated by the EnvironmentObserved template;
• Section Template Parametric Diagram specifies the templates and PLCS PSMTemplate objects instantiated by the EnvironmentObserved template;
• Section Instantiated blocks specifies the templates and PLCS PSMTemplate objects instantiated by the EnvironmentObserved template and bound to private parts of the template;
• Section Default instances species the instances that have been instantiated in the template. These are used to set the default value of blocks.
• Section Constraint blocks identifies the constraint blocks that have been specified in this template;
• Section Example data provides example XML data sets that have been instantiated in accordance with this template.

The EnvironmentObserved template describes how to represent the fact an environment has been observed ((ObservedEnvironment)).

For instance, the temperature (measuredEnvironmentProperty) T=2C has been observed, and therefore the EnvironmentObserved can be linked to an EnvironmentDefinition, defining a "cold" environment when the temperature is in between 0C and 5C.

It can also be linked to the activity (measuringActivity) that performs the measurement in which we could find the meter (for instance) as a resource of this activity.

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

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

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:

The following output ports are defined for this template:

There are no constraints defined for this template.

This section describes the template's Parametric Diagrams. Each diagram details the pattern of templates and PLCS PSMTemplate objects that are required to represent the template EnvironmentObserved.

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.

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:

Figure 5 shows the instances that have been instantiated in the template. These are used to set the default value of blocks.

The following instances have been created:

There are no constraint blocks defined in this template.

No example data sets have been provided for this Template.
