[sprotty-dev] Sprotty for Mining and Analysis Workflow Visualization

[Patrick Neubauer <patrick.neubauer@xxxxxxxxxx>]

Dear Sprotty developers,

We are members of the CROSSMINER EU project, which involves mining of open-source software from various providers, and developed Crossflow, i.e. a language to specify mining and analysis workflows [1]. 

As part of our web application, we would like to graphically visualise the workflow execution during runtime and found Sprotty to be a fitting candidate. 

As a result, we generated an Xtext-based language of Crossflow, i.e. our workflow language, replaced the exemplary “multicore” language with it, and drafted the diagram generator accordingly. 

Although we were able to produce a graph with nodes as well as compute its layout [2], we were unable to successfully visualise the result in the browser [3].

The experiment is available on Github [4] and is fairly easy to reproduce. 

Can you provide any hint on what may go wrong?

Cheers, Patrick
