Application module: Selected item | ISO/TS 10303-1357:2004(E) © ISO |
This clause specifies the EXPRESS schema derived from the mapping table. It uses elements from the common resources or from other application modules and defines the EXPRESS constructs that are specific to this part of ISO 10303.
This clause constitutes the Module Interpreted Module (MIM) of the application module.
This clause also specifies the modifications that apply to the constructs imported from the common resources.
The following restrictions apply to the use, in this schema, of constructs defined in common resources or in application modules:

This subclause specifies the MIM types for this application module. The MIM types and definitions are specified below.
The selected_item_context_items type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the selected_item_context_items type.
NOTE This empty extensible select requires extension in a further module to ensure that entities that refer to it have at least one valid instantiation.

This subclause specifies the MIM entities for this module. The MIM entities and definitions are specified below.
Examples of different classes of selected items are:
EXAMPLE 1 Time Change/Shelf Life Selected Item (TCSI/SLSI) - All items that must be replaced at specific intervals or that have an elapsed time-related shelf life, are designated as TCSIs or SLSIs, as appropriate. These items do not require the rigorous, up-front CM activity (for example FCA/PCA but rather, they concentrate on the post-delivery CM aspects related to traceability in the field. This is commensurate with their emphasis on being changed/replaced at certain times.
EXAMPLE 2 Maintenance Selected Item (MSI) - Certain items whose maintenance requirements dictate a more detailed traceability than normal items, may be designated as MSIs. MSIs emphasize post-delivery traceability for maintenance purposes.
EXAMPLE 3 Support Equipment Selected Item (SESI) - Certain support equipment items that require some additional traceability, but do not require up-front CM activity are designated as SESIs. These items typically require traceability by lot or batch, but not by individual item serial number.
