Central Ontology Store - Finding existing Classes and Properties

[joepio]

Atomic Data aims to increase interoperability. For developers to make interoperable apps, they need to:

• Define their data model using Atomic Data Classes
• Make sure their data model can be found by other developers

This requires a bunch of things that aren't built yet:

• ModelStore: Some sort of website where users can browse existing properties and classes. We could use atomicdata.dev for this, although this might be a bit of scope creep. It should probably provide great search, information about usage frequency, comments / feedback / reviews, alternatives...
• Some method by which apps can say hey I need instances of this thing, please show me. E.g. paths, starting from the Drive and pointing towards the collection. Ideally, we'd re-use the Class subject URL for this, instead of requiring each model to create a new URL.
