8 Technical Reference Model
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).
| Level 1 | Services 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.
