We did discuss this early on but we decided that we could probably go 
further using something like Jena on the server-side than trying to do 
everything in the browser. I think it would be a bit more complicated 
depending on (e.g.) the Javascript libraries available. Probably a good 
place to start would be to check what client-side implementations exist 
for RDF, RDFS, OWL, SHACL, ShEX, SPARQL, et al.; for example:

https://github.com/semantalytics/awesome-semantic-web#javascript

Personally I don't have a lot of experience with such libraries.

Of course the front-end could be largely reused.

I think this is not something we would plan in the short term, though it 
would be very cool to remove the dependency on the server. :)

Best!
Aidan

The intent of the interface is to run small examples, useful for teaching or illustration purposes. In terms of the design, we wanted to show the different standards in a more integrated way (allowing to quickly switch between reasoning, querying and validation, on the same RDF graph, for example), while also putting emphasis on the graph-based nature of RDF through its visualisations (e.g., you can also view the results of reasoning, CONSTRUCT queries, etc., as an RDF graph).
