Understanding the Technical Reference Model (TRM)
The FEA Technical Reference Model (TRM) provides a foundation to describe the standards, specifications, and technologies supporting the secure delivery, exchange, and construction of business (or Service) components and e-Gov solutions. The FEFA TRM unifies existing Agency TRMs and electronic Government (e-Gov) guidance by providing a foundation to advance the reuse of technology and component services from a Government-wide perspective.
Shown below is a depiction of the Technical Reference Model, created in System Architect.

The TRM, illustrated below, outlines the standards, specifications, and technologies that collectively support the secure delivery, exchange, and construction of business and application components (Service Components) that can be used and leveraged in a Component-Based or Service Orientated Architecture. The TRM identifies the core technologies that support the Federal Government information technology (IT) transition towards interoperable e-Government solutions.

The Technical Reference Model (TRM) Domain: The TRM has a four-level hierarchy (Service Area, Service Category, Service Standard, and Service Specification). See figures below.

Note The Service Specification (4th) layer is being dropped for the FY06.

Every TRM definition in each level of the hierarchy has at least three properties: name, description, and a six-digit ID, as shown below. Depending on where they are in the hierarchy, some have parents and children properties as well.
