ProcessShapes are connected using a Sequence. Create the EMF Ecore model for the business processes. After saving, the model will be also updated in the. In the next step, be sure, that the model folder is selected and give a name for the EMF generator model, i.

Select folder and name for the EMF generator model. Select the model importer for the generator model. After, we need to select the EMF. The basepackage needs to be set to the project name and the folder, in which the model resides. Properties view of the genmodel. Now everything is set to generate the model and the edit code. Generate the model and the edit code. Now we may start with the graphical part, defining the notation symbols and map them to the model.

The following view should open: The GMF dashboard. Creation of the GMFGraph model. After being successful, the. This means, that events will be represented by Ellipses and processSteps by Rectangles. Creating the GMF tooling file. The file should look like this: Creation of the GMF tooling file.

Add the Guide Mapping Model Creation to the model folder of the project. Adding the file gmfmap to the project. Leave the following two views also like they are. The last view shows the mapping and should look like this: The mapping when creating the GMFMap file. Set the source feature to ERference source. We need to make some manual amendments, i. Altering the properties of the GMFMap model. Altering mapping properties.

Example of the Diagram Label assignment. Create the generator model. Generate the diagram code from the gmfgen file. Run the. Add a new businessprocess diagram. Now you are able to create a very basic process diagram, which consists of events and processSteps. Create a basic process.

Many references below provide information on how to utilize these frameworks together, some of which inspired the GMF project itself. Another article focusing on the runtime portion of GMF is found here. However, it is likely that most toolsmiths are interested in knowing what is going on under the covers, so a description of each model is linked from the GMF Documentation page. Core to GMF is the concept of a graphical definition model. This model contains information related to the graphical elements that will appear in a GEF-based runtime, but have no direct connection to the domain models for which they will provide representation and editing. An optional tooling definition model is used to design the palette and other periphery menus, toolbars, etc.

Introduction

We start by showing you how to build a very simple data-centric application, including the UI, based on EMF. We explain how to define a model in EMF and generate code from it. We explore the API of the generated code, that is, how to create, navigate and modify model instances. Next we demonstrate how to build a UI based on this model using databinding.
