Modelling

The .ixm Model File

Within the IX Workflow Modeler, the model data are stored in an IXM file. The model file has the "*.ixm" file-name extension. It is an XML file that stores all information of the WorkflowModel in an XML tree according to the following scheme.

The ID attributes for the ProcessEntities are unique for all models. This means that an error is detected during validation if the same ID has been assigned more than once. The same applies to the ID attributes for the ActivityEntities within a ProcessEntity.

The data of a ModelEntity or a configuration entry are managed through an ItemCollection. This allows including attributes as desired and is mapped within the Imixs Workflow API through class org.imixs.workflow.ItemCollection.

You can also create and manage every model file with an XML tool. If you manage several WorkflowModels, the files can be exchanged as desired or shared within a team by using a tool for centralized version control.
