Template: ProxyItem

This section specifies the template ProxyItem.

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 ProxyItem 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 ProxyItem template as described in section Template Parametric Diagram;
Section Template Constraints specifies the constraints on PLCS PSMTemplate objects instantiated by the ProxyItem template;
Section Template Parametric Diagram specifies the templates and PLCS PSMTemplate objects instantiated by the ProxyItem template;
Section Instantiated blocks specifies the templates and PLCS PSMTemplate objects instantiated by the ProxyItem 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 ProxyItem template describes how to represent the fact that an object is the same as an object in reference data.

The SysML Block Definition diagram in Figure 1 shows how proxies are represented in the PLCS PSM.

Related Templates

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

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

Template Block

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.

Template Properties

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

References:

individual [1] (Block: Ap239Ap233Psm:ProxyItemSelect)

a reference to the individual for which a proxy is identified

proxiedBy [0..1] (Block: Ap239Ap233Psm:OrganizationOrPersonInOrganizationSelect)

the person or organization that applied the proxy relationship

Values:

startDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)

the date from which the proxy relationship is applicable.

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

rule.Ap239Ap233Psm.ExternalOwlClass.ur1

Constraint: XSDDATETIME

Specification: (OCL2.0)

self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')

endDate [0..1] (Block: Ap239Ap233Psm:DateTimeString)

the date from which the proxy relationship is no longer applicable

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

rule.Ap239Ap233Psm.ExternalOwlClass.ur1

Constraint: XSDDATETIME

Specification: (OCL2.0)

self.matches('[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}Z')

Template Output Ports

The following output ports are defined for this template:

proxy (Block: Ap239Ap233Psm:Proxy)

Enables the Block: Ap239Ap233Psm:Proxy 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 ProxyItem.

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.

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:datedEffectivity [0..1] (Template: OASIS:DatedEffectivity)

Private Part Property:proxy [1] (Block: Ap239Ap233Psm:Proxy)
