UML Unified Model Language
4 Overview
The present document provides information for putting in operation and for using the Open Source tool Papyrus [i.1]
and the Gendoc plugin [i.6].
The Papyrus tool is used to edit the NFV Information Model and Gendoc [i.6] is an Eclipse™ plug-in integrated with
Papyrus 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 UML tool Papyrus (see [i.1] is a plug-in for the Open Source integrated development environment
(IDE) Eclipse™.
Current tool versions:
• Papyrus version 3.2.x or 3.3.x
• Gendoc version 0.6.x (V0.6.0)
This clause explains how to get Papyrus running and how to create a model.
5.2 Downloading Papyrus
The instructions to download Papyrus can be found in the Papyrus Download page:
https://www.eclipse.org/papyrus/download.html.
The basic procedure is to setup Papyrus with update sites as summarized on the download page:
• The most basic procedure for installing Papyrus consists in installing the Eclipse Modeling Package for your
own platform.
• Then, use the discovery interface ("Help" > "Install Modeling Component") and select Papyrus.
• Install the latest release from Papyrus. See instructions below "Papyrus Update sites".
These steps will be detailed in this clause.
The Oxygen Eclipse Modeling Tools can be downloaded from the Oxygen download page:
https://www.eclipse.org/downloads/packages/release/Oxygen/3.
NOTE: The "Eclipse™ Modeling Tools" package needs to be downloaded, not any other package.

Figure 5.2-1: Eclipse Oxygen Modeling Tools Download Page
Eclipse Oxygen Modeling Tools requires a 1.8 compatible JVM.
Once downloaded, Eclipse™ cannot be "installed" on the target 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.
The initial Eclipse Welcome icon, shown in figure 5.2-3 appears.

Figure 5.2-3: Initial Eclipse Welcome Icon
After launching Papyrus, a default folder is created in the home directory (…/users//). The
workspace configuration information is contained in the folder (which is automatically created):
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 Papyrus.

Figure 5.2-4 shows the initial welcome page of Eclipse.
Close the tab at the upper left corner. Eclipse™ is now ready for initial installation of Papyrus.
