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].)
• Foundation (clause 6.1)
• Data (clause 6.2)
• Time (clause 6.3)
• Test Configuration (clause 6.4)
• Test Behaviour (clause 6.5)

At the end of the document several examples illustrating the features of the TDL Graphical Syntax can be found.

4.3 Notational Conventions
4.3.0 General

Elements from the TDL meta-model [1] are typed in italic, e.g. StructuredDataType.

The definition of the TDL concrete graphical syntax consists of both shapes and textual labels placed into these shapes.

Textual labels are differentiated into non-terminal textual labels and terminal textual labels. The production rule of a

non-terminal textual label is specified by a combination of EBNF symbols and OCL-like expressions to navigate over

the abstract syntax meta-model of TDL.
4.3.1 Symbols and meanings for shapes

Shapes consist of outermost borders, compartments, and textual labels (i.e. non-terminal textual labels and

terminal-textual labels). The following conventions apply:

• Non-terminal textual labels are typed in small capitals (e.g. PRODUCTIONRULELABEL). The name of the label

refers to a production rule with the same name that specifies how the result of the production rule is

determined.
UNDERLINED or BOLD small capitals, underlined or bold
• If a non-terminal symbol name is typed in special, e.g.

font shall be used in the shape for the result of the production rule of that non-terminal symbol, e.g.

S IMPLEDATAINSTANCENAMELABEL (non-terminal) and MyValue:MyType (a result of the production rule of that

non-terminal) or COMPONENT ROLELABEL (non-terminal) and TESTER (a result of the production rule of that

non-terminal), etc.

• Terminal textual labels are typed in non-small-capital characters. They shall be typeset in the same font, as

they appear on the figure, e.g. if a terminal textual label is typed in bold, bold font shall be used in the shape

for that terminal textual symbol, e.g. timer, etc.

• The outermost border of a shape shall not be hidden, unless it is stated explicitly.

• Compartments and non-terminal textual labels may be hidden to simplify the internal structure of the shape.

• In the figures, optional compartments are shaded in a light grey colour, while optional non-terminal textual

labels are typed in grey colour. However, the colour and the shading indicate only the optionality of a

compartment or a non-terminal label. That is, if they are actually present in a test description, they shall not be

shaded and shall be typed in black.

• If a non-terminal textual label is defined to be optional, that non-terminal textual label shall only be shown if

the surrounding compartment is shown and the corresponding non-terminal textual production rule resu

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].)
• Foundation (clause 6.1)
• Data (clause 6.2)
• Time (clause 6.3)
• Test Configuration (clause 6.4)
• Test Behaviour (clause 6.5)

At the end of the document several examples illustrating the features of the TDL Graphical Syntax can be found.

4.3 Notational Conventions
4.3.0 General

Elements from the TDL meta-model [1] are typed in italic, e.g. StructuredDataType.

The definition of the TDL concrete graphical syntax consists of both shapes and textual labels placed into these shapes.

Textual labels are differentiated into non-terminal textual labels and terminal textual labels. The production rule of a

non-terminal textual label is specified by a combination of EBNF symbols and OCL-like expressions to navigate over

the abstract syntax meta-model of TDL.
4.3.1 Symbols and meanings for shapes

Shapes consist of outermost borders, compartments, and textual labels (i.e. non-terminal textual labels and

terminal-textual labels). The following conventions apply:

• Non-terminal textual labels are typed in small capitals (e.g. PRODUCTIONRULELABEL). The name of the label

refers to a production rule with the same name that specifies how the result of the production rule is

determined.

• If a non-terminal symbol name is typed in special, e.g. UNDERLINED or BOLD small capitals, underlined or bold

font shall be used in the shape for the result of the production rule of that non-terminal symbol, e.g.

S IMPLEDATAINSTANCENAMELABEL (non-terminal) and MyValue:MyType (a result of the production rule of that

non-terminal) or COMPONENTROLELABEL (non-terminal) and TESTER (a result of the production rule of that

non-terminal), etc.

• Terminal textual labels are typed in non-small-capital characters. They shall be typeset in the same font, as

they appear on the figure, e.g. if a terminal textual label is typed in bold, bold font shall be used in the shape

for that terminal textual symbol, e.g. timer, etc.

• The outermost border of a shape shall not be hidden, unless it is stated explicitly.

• Compartments and non-terminal textual labels may be hidden to simplify the internal structure of the shape.

• In the figures, optional compartments are shaded in a light grey colour, while optional non-terminal textual

labels are typed in grey colour. However, the colour and the shading indicate only the optionality of a

compartment or a non-terminal label. That is, if they are actually present in a test description, they shall not be

shaded and shall be typed in black.
• If a non-terminal textual l

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].)
• Foundation (clause 6.1)
• Data (clause 6.2)
• Time (clause 6.3)
• Test Configuration (clause 6.4)
• Test Behaviour (clause 6.5)

At the end of the document several examples illustrating the features of the TDL Graphical Syntax can be found.

4.3 Notational Conventions
4.3.0 General

Elements from the TDL meta-model [1] are typed in italic, e.g. StructuredDataType.

The definition of the TDL concrete graphical syntax consists of both shapes and textual labels placed into these shapes.

Textual labels are differentiated into non-terminal textual labels and terminal textual labels. The production rule of a

non-terminal textual label is specified by a combination of EBNF symbols and OCL-like expressions to navigate over

the abstract syntax meta-model of TDL.
4.3.1 Symbols and meanings for shapes

Shapes consist of outermost borders, compartments, and textual labels (i.e. non-terminal textual labels and

terminal-textual labels). The following conventions apply:

• Non-terminal textual labels are typed in small capitals (e.g. PRODUCTIONRULELABEL). The name of the label

refers to a production rule with the same name that specifies how the result of the production rule is

determined.
UNDERLINED or BOLD small capitals, underlined or bold
• If a non-terminal symbol name is typed in special, e.g.

font shall be used in the shape for the result of the production rule of that non-terminal symbol, e.g.

S IMPLEDATAINSTANCENAMELABEL (non-terminal) and MyValue:MyType (a result of the production rule of that

non-terminal) or COMPONENT ROLELABEL (non-terminal) and TESTER (a result of the production rule of that

non-terminal), etc.
• Terminal textual labels are typed in non-small-cap
