The Papyrus tool is used to edit the NFV Information Model and Gendoc i.6 is an Eclipse plug-in integrated with Papyru

25、s that allows generating MS Word documentation of a model from a template. The UML Modeling Guidelines are defined in ETSI GR NFV-IFA 017 i.5. The ONF Papyrus Guidelines (see ONF TR-515 i.4) have been used as a basis for these guidelines. 5 Getting Papyrus running 5.1 Introduction The Open Source UM

26、Ltool Papyrus (see i.1 is a plug-in for the Open Source integrated development environment (IDE) Eclipse. Current tool versions: Eclipse version 4.5.x “Mars“ (V4.5.1) Papyrus version 1.1.x (V1.1.3) Gendoc version 0.5.x (V0.5.1) NOTE 1: Eclipse Neon is not supported yet. NOTE 2: Papyrus Mars release

27、(V1.1.3) requires a 1.7 compatible JVM. This clause explains how to get Papyrus running and how to create a model. 5.2 Downloading Eclipse Eclipse Mars Modeling Tools (see i.2) can be downloaded from here: http:/www.eclipse.org/downloads/packages/eclipse-modeling-tools/mars2 NOTE: The “Eclipse Model

28、ing Tools“ package needs to be downloaded, not any other package. Select the package needed for the operating system as shown on figure 5.2-1. ETSI ETSI GR NFV-IFA 016 V2.1.1 (2017-03) 7 Figure 5.2-1: Eclipse Mars Modeling Tools Download Page Once downloaded, Eclipse cannot be “installed“ on the tar

29、get machine. The zip-file needs to be extracted in a new folder as shown on figure 5.2-2. Figure 5.2-2: Content of the Eclipse folder after extracting the zip-file To launch Eclipse, double-click on the Eclipse.exe file. After launching Eclipse, a default folder is created in the home directory (/us

30、ers/). The workspace configuration information is contained in the folder: . Any empty (need not be empty but is recommended) folder - anywhere - can be used as the workspace-folder. The workspace can be selected during the start of Eclipse. ETSI ETSI GR NFV-IFA 016 V2.1.1 (2017-03) 8 Figure 5.2-3:

31、Initial Welcome page of Eclipse Figure 5.2-3 shows the initial welcome page of Eclipse. Close the tab at the upper left corner. Eclipse is now ready for initial installation of Papyrus. To add Papyrus, click menu and then as shown in figure 5.2-4, figure 5.2-5, figure 5.2-7 and figure 5.2-8. Figure

Figure 5.3-1: Outline of Papyrus perspective ETSI ETSI GR NFV-IFA 016 V2.1.1 (2017-03) 14 Perspective: it provides the modeling context and the layout of the windows, as well as the definition of the menus and toolbars. For using Papyrus

37、, it is always set to “Papyrus“. Project Explorer: it is used to manage Papyrus projects at system level. It provides a view on the model files in the workspace folder. Model Explorer: it provides the internal view of the model selected in the Project Explorer. It is a tree-based model editor for th

38、e whole model. If the Project Explorer contains several models, only one at a time can be selected to be edited in the Model Explorer. Model Editors: it allows graphic edition of the model via diagrams. Class diagrams are the only type of diagram mandated. Property View: it is a form-based editor al

39、lowing to view and edit the detailed property of a given element. Outline View: it provides a read-only view of the model presented in the Model Editor. 5.4 Installing Gendoc plugin installation The Gendoc plugin is used in conjunction with a document template. The template contains instructions tha

40、t enable generation of a MicrosoftWorddocument. The document can include extracts from the model such as diagrams, class definitions, attribute definitions along with their stereotypes, etc. as well as figures and text directly entered into the template. This clause provides instructions on how to i

41、nstall Gendoc followed by guidance on construction of Gendoc templates along with example fragments of templates. Click menu and then as shown in figure 5.4-1.

Every model needs to be contained in a project. NOTE 2: A project can contain zero or more models. The window provides

44、 a view on the model files in the workspace-folder. The window provides the internal view of the model selected in the . The can only show (edit) one model at a time. The actual interface specification is contained in the Information Model and the additional properties of the UMLartefacts are define

45、d in a Profile Model. It is possible to organize the two models in a single project (Alternative 1 in figure 5.5.2) or in two separate projects (Alternative 2 in figure 5.5-2). Figure 5.5-2: Papyrus Model Structure NOTE 3: ETSI NFV Information Model is using Alternative 2: Information Model and Prof

For the ETSI NFV Information Model, the format is NfvInformationModelv.zip. ETSI ETSI GR NFV-IFA 016 V2.1.1 (2017-03) 17 The next step is to import

47、 the OpenModelProfile files and XxxModel files into Papyrus. Right-click in the Project Explorer area to open the menu containing the Import button as shown in the figure 5.5-3.
