Interfaces, factory functions, and data

MDN
#1

It would be useful for us to consider, when thinking about data structures for information about APIs, that it would be useful to be able to back-reference from an interface to the methods in other interfaces that create them.

For example, it would be useful if an object describing the capabilities of the XRSession interface include a reference to the XR.requestSession() method, which is how you get access to session objects.

If I were to add this to our current data system, I’d lobby to add it to InterfaceData.json:

"XRSession": {
  "inh": "EventTarget",
  "impl": [],
  "factories": ["XR.requestSession()"]
},

In fact, I’d probably go one farther and also add a constructors property. If it’s not present, a object has no constructors. Otherwise, it’s one or more methods in the interface which serve as constructors.

I’d rather we do this using mdn‑data, after mdn/sprints#1694.

I’d like to at least get mdn/data#358 merged.

Yes, I meant whichever source we use for that inheritance and implements data. Since we’re currently still using InterfaceData.json, that’s just the one I mentioned outright. I should have been more clear.
