[Vocabulary/JSON-LD context] Reuse existing vocabularies

[RubenVerborgh]

The vocabulary introduces several concepts that already exist elsewhere, such as Course, Student, etc.

We should make an inventory of vocabularies that already exists, and what concepts they already have.

Examples:

• BBC Curriculum Ontology
• Schema.org Course
• …

To be honest, I didn't like the fact that course 'extends' creativeWork, there are a lot of proporties of creativeWork that don't have any meaning for courses

[RubenVerborgh]

That's a fair point of criticism, and I agree (course materials, not courses, are creative works).

However, such comparisons should be done with pros and cons listed. Also, for this concrete case, this should be reported with schema.org. It's a mistake and they should fix it; they will be more popular than whatever we can come up with, so it's important for us as well.

[jhoobergs]

Are they quick with fixing such things? Because I assumed they were quite slow with such things.

[RubenVerborgh]

They are medium fast with such things; we should try as it is easy to make a case for this. I can do it if you want, but we should first document ourselves on the current status and progress of schema:Course; this might very well be already under discussion.
