Stardust/Enhancing and Embedding Stardust/Browser Modeler/Javascript Metamodel

The metamodel of Javascript objects used to implement the Browser Modeler (Lightdust) is supposed to be a superset of the BPMN2 metamodel. As work on the Browser Model was initially started focussed on the metamodel, some names and structures are still driven by originally Stardust needs stemming from Stardust's use of XPDL - but we intend to change this soon.

Overview

The following schema provides an overview of the Lightdust metamodel using indention to describe aggregation, > to describe references and * to indicate to many aggregation or reference

Common Aspects

All model elements have an id and a uuid

Furthermore all model elements hold an attributes object which can be stored to store arbitrary properties

Model

Overview

The model is the root of all elements. Lightdust manages a set of models which can be obtained from the m_model module, via

m_model.getModels()
