CRUBAL

CRUBAL is a language and engine for data about any kind of thing. Everything is a key and a value: records are pairs, a facet's definition is pairs about a key, and rules, contracts, views and packages are pairs too. The engine is universal at the kind level; commerce, media and the rest are packages that attach to kinds.

Folder	Holds	Licence
spec/	the specification, CRUBAL 2, in 13 chapters	CC-BY-4.0
corpus/	the conformance test corpus	CC-BY-4.0
packages/crubal/	the reference implementation, @cruba/crubal (TypeScript first; a Rust core compiled to WebAssembly once the language freezes)	Apache-2.0
packages/crubal-postgres/	the persistent store on Postgres: the log as the truth, every other table rebuilt from it (docs/design/store.md)	Apache-2.0
packages/crubal-host/	the reference host: identity, secrets, adapters, signing, the loops and the HTTP surface (docs/design/host.md)	Apache-2.0

Status: the spec is a complete working draft. The reference implementation passes every conformance level, Reader through Views (87 corpus cases); it was built level by level (Reader, Dictionary, Rules, Store, Exchange, Views); each level is done when its corpus folders pass.

The home of the core definitions and standard packages will be crubal.com.
