The main advantage is that the application data (accounts, history, roles)
are stored in a MongoDB database, so we can access such data from the
Mappings UI for gathering statistics, sharing the user accounts between the
two systems... And, regarding the ontology, it can always be exported to
RDF/XML, Turtle, OWL/XML, Manchester OWL and Functional OWL Syntax, so
that ontology could be used with other systems in the pipeline.
Although there is no REST web service for exporting the ontology, an
ordinary HTTP call would work to export it.

I do not know yet how SHACL works, but maybe it could be used with the
ontology after being exported from WebProtege?

Yes, we took a look at VoCol <https://github.com/vocol/vocol>, and
specifically the Web Turtle Edito
<https://github.com/vocol/vocol/tree/master/TurtleEditor>r it includes, but
it does not scale properly; with the DBpedia ontology loaded, it works very
slow, and users see the whole ontology in a single textbox. Also, we
thought that, as the goal of the project is to make an easy to use
interface, editing directly in turtle format would not be the best for all
the users. We were considering WebProtege because it provides an easier
interface to edit the ontology, and also the option to edit using
Manchester notation for more advanced users.

Thank you very much Sebastian. I will talk about it with my mentors on
thursday. As I said before, it is still a very active discussion. We will
also discuss the options that you and Adam Sanchez proposed.
Regards,
Ismael.
