So far the Mathematica documentation was helpful for learning Mathics3. Can I ask about Mathics...

Q: API, APIFunction, and interoperability

Michael E2What's the difference between the tags api, apifunction, and interoperability? Do we need three distinct tags? Are there others that overlap some of these. Should some be merged? I assume apifunction is about APIFunction[] only, and perhaps does not have a fully justified existence. Still, someti...
