2 Import the reference models into the System Architect encyclopedia: select Tools, iRMA Utilities, Import FEA XML... and select the FEA XML file (FEA_XML_Doc_Rev_2.3.xml file) that you have downloaded.
While the file is being imported, you receive a message asking if you want to rebuild parent-child relationships. Click Yes.
While the file is being imported, you receive a message asking if you would like to remove old reference model definitions. Unless you have previously imported reference model definitions, select No.
3 Wait until you see the “Successfully Imported” notification (depending on your computer’s speed, this process can take several minutes).
Create a Technical Reference Model diagram
1 Create a new diagram of type Technical Reference Model in your encyclopedia.
You can name the diagram with any name that you like. This will be a reference diagram, so you can call it “Technical Reference Model”.
2 On the diagram, select the TRM symbol on the toolbar and draw one on the diagram.
Any name will do; the default is TRM_1. You can name it “TRM”.
3 Double‑click the definition of this TRM symbol.
4 Click Choices in the Child Service Areas property on the Introduction tab. Because you have imported the FEA Reference Model XML file, the encyclopedia is now populated with a number of TRM Service Areas. Select them all and drag-and-drop them into the Child Service Areas property list block. Click OK to close all dialogs.
5 Select the TRM symbol on the diagram, and choose Tools > iRMA Utilities > Build Diagram Hierarchy. The TRM is automatically built, based on the information imported into this encyclopedia from the FEA XML file. This can take several minutes. The hierarchy reflects the TRM, and include the TRM Service Area, TRM Service Category, and TRM Service Standard.
