8.2 Structure
Organised in a hierarchy, the TRM categorises the standards and technologies that collectively
support the secure delivery, exchange and construction of business and application Service
Components that may be used and leveraged in a component-based or service-oriented
architecture (CBA or SOA, used synonymously from here onward).
The TRM consists of:
Level 1 Service Areas represent a technical tier supporting the secure construction,
exchange, and delivery of Service Components. Each Service
Area aggregates the standards and technologies into lower-level
functional areas. Each Service Area consists of multiple Service
Categories and Service Standards. This hierarchy provides the
framework to group standards and technologies that directly
support the Service Area.
Level 2 Service Categories classify lower levels of technologies and standards with respect
to the business or technology function they serve. In turn, each
Service Category is comprised of one or more Service
Standards.
Level 3 Service Standards define the standards and technologies that support a Service
Category. To support agency mapping into the TRM, many of
the Service Standards provide illustrative specifications or
technologies as examples.
A high-level outline of the TRM is shown in Figure 8-2.
