To add to David’s reply If you have an ontology in EDG, it is not a file. It is a graph in the EDG triple store.
1. You can run EDG locally from TBC. In this case, EDG and TBC share the same workspace 2. Normally, EDG is installed on a server and its workspace is different from your local TBC workspace. In either situation, you can clear EDG ontology and re-import (physically load) RDF file - from your local workspace or from any file directory you have access to. If this does not work for you, I have no explanation. It most definitely works. Further, EDG ontology could contain owl:imports statement to a file in the workspace. You would not, of course, be able to change anything in that imported file in EDG because it would just be included by reference. You could “build on top of it” e.g., create subclasses. You can make changes to it in TBC. If you are running EDG locally from TBC, then any changes you make to the file in a workspace referenced by owl:imports will be automatically reflected in EDG. Having said this, if you use other graphs to store instances of classes defined in this file, the fact that something has changed in the class definition may not be picked up by EDG and the schemas used for data would not be regenerated. I have not tried this, so I am not sure. If this is a problem. Making any change in the ontology in EDG would trigger regeneration. If you are running EDG from the server, then, as David explained, you will need to re-deploy your changed file to the server. > On Jan 29, 2020, at 11:19 AM, dprice <[email protected]> wrote: > > Hi Michel, > > Depends on what you mean: > > Do you mean running EDG from TBC?
