The "[strongly typed](https://en.wikipedia.org/wiki/Strong_and_weak_typing) sheets" system of the CellOS.

- Typing discipline: "[structural](https://en.wikipedia.org/wiki/Structural_type_system)"

- Strongly typed object relational mapper (ORM) for two-way binding of `[sheets] : {objects}`.

- Generation of standards based type declarations from globally addressable `cell:namespace` definitions for consumption by industry standard tooling:
    - [Typescript](https://en.wikipedia.org/wiki/TypeScript) type symbols from globally addressable cell `namespace` definitions.
    - [GraphQL](https://en.wikipedia.org/wiki/GraphQL) schema definition language ([SDL](https://graphql.org/learn/schema/)) symbols - **[Coming Soon 🐷]**

- Advanced type concepts including type OR'ing ("|"), grouping, referencing (aka "fancy" typesystem).
