4 Basic principles
4.1 Introduction

The meta-model of the Test Description Language is specified in ETSI ES 203 119-1 [1]. The presentation format of

the meta-model can be different according to the needs of the users or the requests of the domain, where the TDL is

applied. These presentation formats can either be text-oriented or graphic-oriented and may cover all the functionalities

of the TDL meta-model or just a part of it, which is relevant to satisfy the needs of a specific application domain.

The present document specifies a concrete graphical syntax that provides a graphical representation for the whole

functionality of the TDL meta-model.

The document specifies the TDL diagram, where the graphical representations of the instances of the TDL meta-classes

may be placed. A graphical representation may contain a shape with textual labels placed into it. The rules, how these

labels shall be interpreted are described in OCL-like expressions.
4.2 Document Structure

The present document specifies the concrete graphical syntax of the Test Description Language (TDL).

Clause 5 specifies the TDL Diagram.

Clause 6 specifies the concrete shapes defined for the TDL meta-classes. (The meta-model of TDL and the meanings of

the meta-classes are described in ETSI ES 203 119-1 [1].)
