UNE-EN IEC 62559-3:2018

In order to exchange use cases based on the template which is defined in IEC 62559-2 this part of the IEC 62559 Use case methodology establishes the interfaces between the different use case repositories and / or UML engineering software tools.



Therefore, this document defines the required core concepts and their serialization into XML syntactic format of a use case template, an actor list and list for detailed requirements.



As shown in Figure 2, the modelling approach is leveraging the use of UML in order to graphically represent the data contained in a use case based on the 62559 template. Therefore the textual format of the use case template may be in the use case development process just a starting point for business experts or easy way for modifying use case data for non UML experts. As a consequence, IEC 62559 standard series needs to provide a reliable way for converting this textual format into UML format and reciprocally. As soon as a use case repository is maintained based on 62559 standard series, another related need is to be able to import/export between different UML tools and different use case repositories the use case related information based on a tool independent format.



The main purpose of this part 3 standard is to propose an independent format for transferring the use case information between modelling software. In order to satisfy this goal, the syntactic XML format is chosen to serialize the use case data. This part 3 standard is defining in detail the core concepts of the template into UML and their transformations into XML using the XSD standard.
