Term Definition<br />
Technical <strong>Reference</strong><br />
Model (TRM) [top]<br />
A component-driven, technical framework used to categorise the standards,<br />
specifications and technologies that support and enable the delivery of service<br />
components and capabilities. The TRM provides a foundation to categorise the<br />
standards, specifications and technologies to support the construction, delivery<br />
and exchange of business and application components (Service Components)<br />
that may be used and leveraged in a Component-Based or Service-Oriented<br />
<strong>Architecture</strong>. The TRM unifies existing Agency TRMs and E-Gov guidance by<br />
providing a foundation to advance the re-use of technology and component<br />
services from a government-wide perspective. Service areas include: Service<br />
Access and Delivery, Service Platform and Infrastructure, Component<br />
Framework, and Service Interface and Integration (http://www.finance.gov.au/egovernment/index.html).<br />
Term [top] One or more words designating a concept. (ANSI/NISO Z39.19-200x)<br />
Term Record A collection of information associated with a term in a controlled vocabulary,<br />
including the history of the term, its relationships to other terms and, optionally,<br />
authorities for the term. (ANSI/NISO Z39.19-200x)<br />
Thesaurus [top] A networked collection of controlled vocabulary terms. A thesaurus uses<br />
equivalence (synonym), hierarchical (broader/narrower) and associative<br />
relationships. The expressiveness of the associative relationships in a<br />
thesaurus varies and can be as simple as ‘related to term’, as in ‘term A is<br />
related to term B’. (ANSI/NISO Z39.19-200x)<br />
Topic [top] A category within a Taxonomy. A Topic is the central concept for applying<br />
context to data. For example, an agency may have a Taxonomy that represents<br />
its organisational structure. In such a Taxonomy, each role in the organisational<br />
structure (e.g. CIO) represents a Topic. Topic is often synonymous with Node.<br />
(DRM usage)<br />
Top Term [top] The broadest term in a controlled vocabulary hierarchy. (ANSI/NISO Z39.19-<br />
200x)<br />
Transaction [top] An exchange of information between two or more services (or an entity and a<br />
service) in the performance of an operation or function. (DRM usage)<br />
Transactional Database<br />
[top]<br />
A database that support transactions. A database transaction is a unit of<br />
interaction with a database management or similar system that is treated in a<br />
coherent and reliable way independent of other transactions that must be either<br />
entirely completed or aborted.<br />
Tree Structure [top] A controlled vocabulary display format in which the complete hierarchy of terms<br />
is shown. Each term is assigned a tree number or line number which leads<br />
from the alphabetical display to the hierarchical one; the latter is also known as<br />
systematic display or classified display. (ANSI/NISO Z39.19-200x)<br />
TRM [top] See Technical <strong>Reference</strong> Model.<br />
Unified Modeling<br />
Language (UML) [top]<br />
A non-proprietary, object modelling and specification language. As a graphical<br />
notation, UML can be used for modelling hardware (engineering systems) and<br />
is commonly used for business process modelling, systems engineering<br />
modelling, software engineering and representing organisational structure.<br />
UML was designed to be used to specify, visualise, construct and document<br />
