Use of this field is optional. If you choose
to use it, select the category that most closely
describes the service performed by your proposed
component. You may select one and only one
category. If the proposed ET component falls
into more than one category, logically speaking,
it comprises more than one component and should
be broken down accordingly. However, if your
proposed ET component does not fit neatly into
one of the existing categories, you may propose
a new category, by selecting the value “Propose
Service Type” and entering a name for the proposed service
category in the adjacent field. (See Figure 1)
In the context of the ET.gov site and process,
the primary purpose of the controlled vocabulary set forth in the
Federal Enterprise Architecture (FEA)
Service Component Reference Model (SRM) is
to facilitate discovery of software service components. The SRM is
organized as a functional hierarchy, with
Service Domains at the highest level, followed
by Service Types and Components. Service Types further categorize
and define the capabilities of a Service
Domain.
Until such time as the FEA Data Reference Model
(DRM) is available for referencing, it may be worthwhile to classify
some ET components of the data
Component Type under the SRM, particularly
if those components are Web Services. (In the context of the ET.gov
site/process, Web Services are
considered to be Web sites that transmit valid
XML instance documents upon request.)
For more information on the SRM, see
