Would you consider going open source with community edition to be released on hubs like gitlab or github including OpenAPI etc. I think Visual Paradigm has long history (I personally used already many years back), but the velocity of new features is not much changing… (no support fo Big data and/or graph databases and new popular schema management Json/Avro schemas…)…its still same as few years back…
Also creating something like online Plugin repository might help. Simply do something cool, don’t stay back.
Performance: The whole solution is quite slow reacting when working with large number of objects and such experience I have from first time (I don’t know exactly how many years back) I used VP, not much changed here during so may years…
Maybe opening some parts of code and bringing community into this might help to make things better , also there are already tools like Portege for full Ontology design which might be integrated, etc.
Thanks for answer.
