The Part template describes how to represent a part. It
covers the minimum requirements to represent a
Part
PartVersion
and
PartViewDefinition.
NOTE
In previous editions of PLCS DEXlib organization that do not version parts were recommended
to set the identification of the
PartVersion
to "/NULL", i.e. the attribute
identifier
of entity
Identification
contains the string "/NULL" to indicate
that no version information is relevant or intended.
The current recommendation is to provide no versionId. This will result a single unidentified
PartVersion being produced.
The SysML Block Definition diagram in Figure 1
shows how a Part is represented in the PLCS PSM.
The following Part, Reference, and Value properties are defined for this template:
References:
Parts:
ids [1..*] (Template: OASIS:
Identification)
The collection of identifiers of the part.
There shall be at least one identifier that is the part number. Hence there shall
be at least
one identifier classified to
be a "Part_identification_code" or a sub-class of "Part_identification_code".
The reference data used in Template: OASIS:
Identification is restricted as follows:
RDL constraint 1:There must be one identifier that is the part number.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
versionId [0..1] (Template: OASIS:
Identification)
The identifier of the part version.
NOTE
If no versionId is specified a unique, unidentified PartVersion is created.
The reference data used in Template: OASIS:
Identification is restricted as follows:
RDL constraint 1:The identifier must be a version identifier.
The reference data for:
OASIS:Identification.role -> ExternalOwlClass.class
is restricted to the following class or a subclass:
classifications [0..*] (Template: OASIS:
Classifier)
The classification of the part.
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:
viewClassifications [0..*] (Template: OASIS:
Classifier)
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:
names [0..*] (Template: OASIS:
Name)
The names of the part
