R1-3.2 Retrieve SEMIObjType Descriptions — This use case provides a way for an application to request a
description of all of the SEMI standard OSS ObjTypes supported by the equipment. This supports automated usage,
so that applications that are written to work with OSS ObjTypes can discover which ObjTypes are in use on a
specific equipment installation, and can learn the event id’s that the supplier uses for standardized state transitions.
Figure R1-3 shows one example of how this use case can be realized using messages from the interface defined in
this specification (see Section 9).

R1-3.3 Retrieve Exception Descriptions — This use case provides a way for an application to request a description
of all of the exceptions generated by the equipment, and to determine which components of the equipment generate
which exceptions. This supports automated usage, so that applications that are looking for standardized or well-
known equipment specific exceptions can discover their existence on a specific tool. It also supports any manual
usage in which a human user would like to understand available equipment-specific exceptions. Figure R1-4 shows
one example of how this use case can be realized using messages from the interface defined in this specification (see
Section 9).

R1-3.4 Retrieve Equipment Parameter Descriptions — This use case provides a way for an application to request a
description of all of the data items provided by the equipment, and to determine which components of the equipment
provide that data. This supports automated usage, so that applications that are looking for standardized or well-
known equipment-specific data items can discover their existence on a specific tool. It also supports any manual
usage in which a human user would like to browse and understand equipment-specific data that has not been
standardized. Figure R1-5 shows one example of how this use case can be realized using messages from the
interface defined in this specification (see Section 9).
