Example Of The XML Structure For Shared Components
6.3.4 In summary, with this approach, the structure of the equipment is readily apparent in the XML instance
document except for the components that are shared. When a component is shared, its definition does not need to be
repeated. Instead, a reference by uid is provided. This avoids additional complexity and duplication that could bloat
the XML instance document.
6.3.5 Equipment => EquipmentType
6.3.5.1 The Equipment class is mapped to the XML EquipmentType. EquipmentType extends the
ExecutionElementType (see Figure 8). It is also a container for all of the components of the Equipment – Modules,
Subsystems, IODevices, MaterialLocations, and other Equipment.
6.3.5.2 Table 7 shows how the associations of the Equipment class are mapped into XML. The EquipmentType
contains the element EquipmentComponents to act as a container. The XML elements listed in the table are
contained in EquipmentComponents.

6.3.6 Module => ModuleType
6.3.6.1 The Module Class is mapped to the XML ModuleType. The ModuleType extends the
ExecutionElementType (see Figure 9). It is also a container for all of the components of the Module – Subsystems,
IODevices, MaterialLocations, and other Modules.
6.3.6.2 Table 8 shows how the attributes and associations of the Module class are mapped into XML. The
ModuleType contains the element ModuleComponents to act as a container. The XML elements listed in the table
are contained in ModuleComponents.
