Template: OASIS:StockItem

This section specifies the template StockItem.

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

The specification comprises the following sections:

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

The StockItem template describes how to represent the identification of a stock item.

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

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

Figure 1 shows the SysML Block that represents the template. The Block is an abstraction representing a pattern of templates and PLCS PSM 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.

Figure 1 -  Template block definition diagram for StockItem

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

References:
ids [1..*] (Template: OASIS:Identification)
The identifiers of the stock item.
The reference data used in Template: OASIS:Identification is restricted as follows:
RDL constraint 1:
The ids must be classified as a stock number code or sub class of stock number code.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
Example reference data is:
Parts:
resourceItemSelect [1..*] (Block: Ap239Ap233Psm:ResourceRealizationSelect)
The item that is identified as a stock item. Normally a Part.

The following output ports are defined for this template:

resourceItem (Block: Ap239Ap233Psm:ResourceItem)
Enables the Block: Ap239Ap233Psm:ResourceItem instantiated by this template to be referenced when the template is used.
resourceRealization (Block: Ap239Ap233Psm:ResourceItemRealization)
Enables the Block: Ap239Ap233Psm:ResourceItemRealization 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 PSM objects that are required to represent the template StockItem.

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 the Parametric Diagram.

PLCS PSM objects are shaded khaki and template 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:resourceItem [1] (Block: Ap239Ap233Psm:ResourceItem)
Private Part Property:resourceItemRealization [1..*] (Block: Ap239Ap233Psm:ResourceItemRealization)

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

Instance diagram
Figure 3 -  Model instance diagram for StockItem

The following instances have been created:

classStockNumberCode instance of Block: Ap239Ap233Psm:ExternalOwlClass.

This is the standard classification of a stock number code and is used as constraint on the id.
classNSNCode instance of Block: Ap239Ap233Psm:ExternalOwlClass.

This is the NATO Stock Number code and is a standard id classification in the defense industries.

There are no constraint blocks defined in this template.

The following section provides an example XML dataset that has been instantiated in accordance with this template.

Data set: NSN number

This example shows the XML instantiated to represent an NSN code assigned to a Part.
