RELATED INFORMATION 2
OBJECT MODEL
NOTICE: This related information is not an official part of SEMI E99. This related information was approved for
publication by full letter ballot procedures on August 28, 2000.
R2-1 Object models provide a graphic representation of entities. The models in this section use the Object
Modeling Technique (OMT) described in Object-Oriented Modeling and Design. Object types are represented by
rectangles with one, two, or three sections. The name of the object type is in the first, or only section. Attributes,
information about the object, are shown in the second section. Operations or services are shown in a third section.
Lines between objects represent relationships.
R2-2 Three models are shown for purposes of illustration. The general multi-head case is shown first with only the
required attributes and services. Next, the full model for the multi-head case is shown with all attributes and
services defined in this standard. Finally, the full model for the integrated single-head case is shown.
R2-3 Note that the Upstream Controller sends all service requests to the CIDRW controller, including services
shown for the individual heads. Services shown on these models for CIDRW are those with a Head ID service
parameter value of zero while services shown for the Head are those with a Head ID service parameter value
between one and thirty-one.
R2-4 Fundamental Requirements Example Object Models
R2-4.1 The object model in Figure R2-1 shows objects for the general (multi-head) CIDRW satisfying fundamental
requirements only. It shows the CIDRW subsystem as made up of one or more heads. It also illustrates the required
attributes and services provided by the CIDRW and its relationships with its upstream controller and with its heads.

R2-5 Full Capabilities
R2-5.1 Figure R2-2 shows the object model for a CIDRW with full capabilities, so that all optional attributes and
services are supported.

R2-6 Integrated Model
R2-6.1 Figure R2-3 shows the object model for a CIDRW with full capabilities and a single integrated head. The
head is not shown as a separate component in this case, and the head attributes and services have become part of the
CIDRW subsystem itself.
