Template: Name

This section specifies the template Name.

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 Name 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 Name template as described in section Template Parametric Diagram;
Section Template Constraints specifies the constraints on PLCS PSMTemplate objects instantiated by the Name template;
Section Template Parametric Diagram specifies the templates and PLCS PSMTemplate objects instantiated by the Name template;
Section Instantiated blocks specifies the templates and PLCS PSMTemplate objects instantiated by the Name 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.

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

Description

The Name template describes how to represent a name of an object. A name is cue to a user to help identify or classify the object, but may not be unique and may change with the language used. For example, "Noddy" is the name of a character in a children's story in England, but who is called "Oui Oui" in France.

NOTE A unique identifier of an object is represented by the Identification template.

Related Templates

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

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

Template Block

Figure 1 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.

Template Properties

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

References:

context [0..1] (Block: Ap239Ap233Psm:IdentificationContextSelect)

The context within which the name has been defined. Typically an organization that "owns" the name.

Parts:

name [1] (Block: Ap239Ap233Psm:LocalizedString)

the name being assigned.

Template Output Ports

The following output ports are defined for this template:

descriptor (Template: OASIS:Descriptor)

Enables the Template: OASIS:Descriptor instantiated by this template to be referenced when the template is used.

Template constraints

There are no constraints defined for this template.

Template Parametric diagram

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 Name.

The public properties, i.e. those visible in the template's SysML block (See Figure 1) 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.

Instantiated Blocks

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:descriptor [1] (Template: OASIS:Descriptor)

Private Reference Property:nameClass [1] (Block: Ap239Ap233Psm:ExternalOwlClass)

The following constraint, normally a uniqueness constraint, is applicable when instantiating the ExternalOwlClass:

rule.Ap239Ap233Psm.ExternalOwlClass.ur1

Constraint: ur1

Specification: (OCL2.0)

ExternalOwlClass::allInstances()->isUnique(class)

Private Part Property:classifier [1] (Template: OASIS:Classifier)

Default instances

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

Instances

The following instances have been created:

nameCode instance of Block: Ap239Ap233Psm:ExternalOwlClass.

ExternalOwlClass.class = http://docs.oasis-open.org/plcs/ns/plcslib/v1.0/data/contexts/OASIS/refdata/plcs-rdl#Name

The classification of the Descriptor as a name.

Constraint Blocks

Figure 3 shows the constraint blocks that have been created in the template.

Constraint Blocks are typically used to combine blocks into a collection that can then be bound to a property. For example, combining a set of identifications that can then be bound to property of type Identification.

Figure 3 - Constraint block diagram for Name

The following constraint blocks have been created:

Constraint: CombineNamesAndDescriptors

Specification: (OCL2.0)

combined=descriptors.descriptor->union(names.descriptor.descriptor)

Combines names and descriptors together for assignment into PSM blocks expecting Descriptor's.

Example data

No example data sets have been provided for this Template.
