GetSEMIObjTypesRequest Global Element
7.2.11.5.1 GetSEMIObjTypesRequest — This global element acts as a top-level container entity representing the
SOAP body of a GetSEMIObjTypes request. As defined in SEMI E125, this operation has no input arguments, so
the element has no contents.
Figure 19
GetSEMIObjTypesResponse Global Element
7.2.11.5.2 GetSEMIObjTypesResponse — This global element acts as a top-level container entity representing the
SOAP body of the response to an SEMI E125 GetSEMIObjTypes request. It contains either zero or more elements
named “ObjType” of complexType “SEMIObjTypeType” or an element named “Error” of complexType
“ErrorType”, defined in SEMI E138.

7.2.11.5.3 SEMIObjTypeType — This global complexType is the XML Schema representation of the SEMI E125
SEMIObjType class. Attributes and eventData are provided using the ParameterType, defined in ¶7.2.14.5.4.

7.2.11.5.5 ParameterReferenceType — This global complexType is the XML Schema representation of a reference
to a Parameter defined in the equipment metadata. Referenceable Parameters are defined either by SEMIObjTypes
as “Attributes” or “EventData”, or by equipment nodes in the set of Parameters provided with
“EquipmentNodeDescription” metadata. Equipment nodes and SEMIObjTypes are said to be valid Parameter
“sources”. Parameters defined for Exceptions are not referenceable. This type defines two attributes, “source” and
“name” that are used to uniquely identify Parameters in equipment metadata.
7.2.11.5.5.1 Parameter references may be “absolute” or “relative”. An absolute Parameter reference is used when
referring to a Parameter that is defined by a different source than the one making the reference. A relative reference
SEMI E125.1-0305 © SEMI 2005 30
is used when referring to a Parameter that is defined by the same source as the one making the reference. It is
expected that the most common Parameter references in equipment metadata will be relative references.
7.2.11.5.5.1.1 For an example of an “absolute” reference, consider two equipment nodes: a
“TemperatureController” equipment node that provides a “TemperatureSetpoint” Parameter; and a
“TemperatureSensor” equipment node that provides a “MeasuredTemperature” Parameter. The
“TemperatureSetpoint” Parameter is a control Parameter whose setting affects the “MeasuredTemperature”
Parameter, so it may need to refer to that Parameter from the context of the “TemperatureController” node. In this
case, an “absolute” reference is required, since the “referred-to” Parameter is defined by a different node than the
node making the reference.
7.2.11.5.5.1.2 For an example of a “relative” reference, consider a SEMIObjType that has a SEMI E39 attribute
defined for it that stores the current state of the object. In the StateMachineInstance for that same SEMIObjType,
the “CurrentStateName” element is used to refer to a Parameter that can be used to determine the current state of
that StateMachine. In this case, the Parameter belongs to the same “source” (the same SEMIObjType) that
implements the StateMachine, so a relative reference can be used.
7.2.11.5.5.2 source — This attribute is optional and shall be either not present (relative reference) or present and set
to a valid CEM Locator (absolute reference) identifying the equipment node that provides the referenced Parameter.
If not present, the source is inferred by the context that the reference is made (either a SEMIObjType or an
equipment node).
7.2.11.5.5.3 name — For relative references to Parameters provided directly from an equipment node or
SEMIObjType, this attribute shall be set to the value of the “name” attribute of the Parameter that is referred to. For
absolute references to Parameters provided directly from an equipment node, this attribute shall be set to the value of
the “name” attribute of the corresponding Parameter. For absolute references to SEMIObjType attributes or event
data Parameters provided from a specific equipment node, this shall be a string of the form “urn:semi-
org:objType:<typeName>:objAttr:<parameter name>”, where “<typeName>” is the ObjType name, and
“<parameter name>” is the name of the Parameter representing the attribute or event data.
7.2.11.5.5.4 Some examples of valid Parameter references are shown in the following table.
