About

This system is experimental, and replaces/updates the old content system (which was really part of 0.2 or 0.3).

Each node represents the core of a pseudo-record, which can have an arbitrary set of fields (leafs). Each leaf (field within a p-record) must have a unique name.

There are two registries maintained by code:

  • Pseudorecord types (node.Type)
  • Leaf types (leaf.Type)
