I am involved in a project and I would like to ask for some advice, opinion, ideas...

The thing is that we have some data stored in a triple-store (GraphDB), with some related ontologies, SHACL rules and SHACL forms. Those are related to our domain of knowledge.

Then we need to implement some workflows/procedures which consume data from those knowledge graphs process them (with user intervention) and show some forms dynamically generated on the basis of the Ontologies, and the SHACL.

One of the approaches I am considering is to use BPMN 2.0 to model those workflows and then have them exported as BPMN 2.0 XML (e.g.). Then, those workflows would be processed by a BPMN execution engine to implement the web application.

The challenge here is to find a BPMN execution engine and orchestrator which is able to consume data from the knowledge graph through SPARQL queries and present it as forms generated from SHACL forms and implementing validation rules from the SHACL rules.

Any idea? Opinions? Advice?

Thanks to everybody reading this and trying to help. :)
