Object model
Six primitives — person, organisation, project, opportunity, learning path, evidence — from which every surface is composed.
In a suite of products, each product invents its own nouns and you restate yourself at every border. In a world, there is one set of nouns and every surface is a view over them.
This is the structural reason the civilization can be coherent at all: a project in a studio, a contract in the persistent world and a credential in an academy are the same objects, and they resolve to the same record.
