I have read through the forum and come across many examples on how to extend the Bpmn moddle with a custom meta model. But is there a guide available on how to roll out a custom model built on diagram-js rather than bpmn-js. Any guide on how to achieve this will be helpful. And ideally this custom moddle will be integrated into the diagram-jseditor example as the foundation.
What problem are you trying to solve with a custom moddle? Generally, you do not need a moddle if you only use diagram-js for rendering, but it might be worth it if you want to persist your data in XML. Note that you can also use your own meta-model to store info and don’t necessarily need to commit to moddle.
