Data Infrastructure is the foundation of Oxygen: it gets your data in, shapes it, and compiles it into the queries your World Model and agents run. Three engines do the work, each open where it makes sense to be.

Airhouse

The managed warehouse and connector. Workspaces mint short-lived, ephemeral credentials from a service account — there’s no long-lived key to rotate.

Airlayer

The core of the World Model — an in-process semantic engine that compiles YAML schemas into dialect-specific SQL. Open source.

Airform

dbt-style modeling — version-controlled SQL transforms that land clean, tested tables for the semantic model to build on. Open source.

​
How they fit together

1

Land

Data arrives in Airhouse (or your own warehouse).
2

Shape

Airform models raw tables into clean, tested ones.
3

Compile

Airlayer compiles your semantic definitions over those tables into correct SQL — the foundation the World Model reasons over.
