Resource modeling tooling comes with SML editor and validator.SML validator validates SML and SMLIF files.
After downloading these packages unzip them to same directory. If Eclipse is already installed in the user environment then it is important that you do not choose a different folder, as the zip file includes path information so that the feature and plug-in files are installed in the correct folders.
Restart the Eclipse workbench (if already running) to activate the new plug-ins.
Note: An alternative to restarting the workbench is to select File > Switch Workspace and click OK to select the current workspace. This operation causes Eclipse to reload all features and plug-ins.
For an alternative installation method, you can manually copy the contents of the downloaded SML-IF tooling plug-in zip file to Eclipse installation directory. The zip file contains a plugins folder and a features folder inside the uncompressed download.
Use this procedure.
Resource Modelling Tools usage details can be found in the COSMOS Users Guide.
