34、 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
35、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 graphic
36、al representations of the instances of the TDL meta-classes can be placed. A graphical representation can 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
37、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
38、) 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 i
39、talic, 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
40、 is specified by a combination of EBNF symbols and OCL-like expressions to navigate over the abstract syntax meta-model of TDL. ETSI ETSI ES 203 119-2 V1.1.1 (2015-06)8 4.3.1 Symbols and meanings for shapes Shapes consist of outermost borders, compartments, and textual labels (i.e. non-terminal text
41、ual 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
42、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. g94g47g68g87g62g28g24g4g100g4g47g69g94g100g4g69g18g28g69g4g68g28g62g4g17g28g62 (non-termina
43、l) and MyValue:MyType (a result of the production rule of that non-terminal) or g18g75g68g87g75g69g28g69g100g90g75g62g28g62g4g17g28g62g3(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
44、 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
45、 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 indicates only the optionality
46、 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 can only be shown if the surrounding compartment is
47、 shown and the corresponding non-terminal textual production rule results in a non-empty string or a non-empty collection of strings. If an optional compartment contains a mandatory terminal or non-terminal textual label, the text shall only be shown if the surrounding compartment is shown. Referenc
48、es to non-terminal textual production rules external to the given shape are represented by the name of the referenced production rule enclosed in angle brackets (e.g. ). A non-terminal textual label in between hashmarks (e.g. #ELEMENT#) denotes a placeholder for a shape identified by that non-termin
49、al textual label. 4.3.2 Symbols for non-terminal textual labels Non-terminal textual labels are specified by production rules (so called non-terminal textual label production rule). The formal specification of a non-terminal textual label production rule is expressed by OCL. The context meta-model element for the OCL expression is specified prior to the non-terminal textual label specification. In some cases, the definition of OCL expression would be too complex for understanding. In that case, pseudo-code like helper notations a
