32、cription Language URI Unified Resource Identifier 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, whe
33、re 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 graph
34、ical 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 labe
35、ls 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 s
36、hapes 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 exampl
37、es illustrating the features of the TDL Graphical Syntax can be found. ETSI ETSI ES 203 119-2 V1.2.1 (2016-09)8 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 bo
38、th 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 abstr
39、act 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. PRO
40、DUCTIONRULELABEL). 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 fo
41、r the result of the production rule of that non-terminal symbol, e.g. g94g47g68g87g62g28g24g4g100g4g47g69g94g100g4g69g18g28g69g4g68g28g62g4g17g28g62 (non-terminal) and MyValue:MyType (a result of the production rule of that non-terminal) or g18g75g68g87g75g69g28g69g100g90g75g62g28g62g4g17g28g62g3(no
42、n-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 t
43、he 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 shade
44、d 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 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
45、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 results in a non-empty string or a non-empty collection of strings. If
46、an optional compartment contains a mandatory terminal or non-terminal textual label, the text shall only be shown if the surrounding compartment is shown. References to non-terminal textual production rules external to the given shape are represented by the name of the referenced production rule enc
47、losed 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-terminal textual label. 4.3.2 Symbols for non-terminal textual labels Non-terminal textual labels are specified by production rules (so called
48、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 ex
49、pression would be too complex for understanding. In that case, pseudo-code like helper notations are used. ETSI ETSI ES 203 119-2 V1.2.1 (2016-09)9 The OCL expressions are combined with a variant of the Backus-Naur Form (Extended Backus-Naur Form - EBNF). The conventions within the present document for the production rules are: OCL keywords and helper functions are typed in bold. The keyword context followed by the name of TDL metaclass determines the context element for the following production rule (e.g. context Package).
