How many workshops can I have interacting/editing the same Ontology objects

In a push to centralize our Ontology and iterate on scalability and reusability we’re looking to consolidate similar Ontology objects. Are there any scalability/load-balancing issues we should be mindful of when doing this? For instance could 10+ applications all use an Ontology object in it and be making edits to the objects in parallel? Are there user scalability limits we should be mindful of?

No, that should be totally fine from a correctness perspective, but you may need to include more error handling to let users know if their actions are going to conflict with one another.
