Divergence between record ontology and VRE frontend

The frontend has its own JSON-LD copy of the record ontology. Yesterday, I wanted to check whether it was up-to-date with the ontology in the dedicated repository, so I ran the script in the latter to generate its latest JSON-LD. The differences were more significant than I expected:

The red parts of the diff correspond to the VRE frontend, the green parts to the dedicated repository. I had to change the order of the output of the JSON-LD script in order to keep the diff minimal.

I will be investigating what needs to be done to reconcile the two. @tijmenbaarda if you could share anything you know that might help to clear up matters, please do.
