Learn Columna

One place that gathers the orientation, the three manuals, the live Explorer, and how to run it. New to the vocabulary? Start with What is Columna?

Start here

The Theory of Data in One Afternoon The whole idea in one sitting, from a cold start — four failures you have probably debugged yourself, the world they imply, and the queries that fall out of it. No prior reading needed.
What is Columna? A plain-language orientation — the pieces, by analogy, and the four moods an answer arrives in.
What is FrameQL — and why? The query language in plain language — the Frame is the query, the three-part column, and where SQL and FrameQL part ways.
A Primer on Frame-QL The shortest conceptual on-ramp (8 min) — why the result can be the query, and why the output anchor is not always enough. The deposited edition, v2.2.
Frame-QL: An Introduction The fuller conceptual account (25 min) — the frame as the request, the two anchors, and where AI belongs at the intent boundary. The deposited edition, v2.3.
What is a Manifold? The hub of the set — the new data model: substance where relational was form, and why its claims stand trial.
What is a universe? The territory a question is asked in — a base, the many-to-one arrows that do not lie, and the two lawful ways to cross between universes.
What is the Theory of Data? The foundation, in plain prose — datums, measure families and their measures (a family at one anchor), frames, and lawful transformation. The accessible conceptual entry to the canonical paper.
Why Columna looks the way it does Where the structure came from — mostly not designed but written down, and why the taste-versus-no-choice lens changes how you evaluate it.
The Explorer The demo Manifold, live — every measure, universe, and edge with its law, its verdict, and a query to try.
Install Run it in two minutes — a clarify, a refuse, and a disclose print on your machine as real wire JSON.

The manuals

The framework manual (6e) The full discipline, precisely — the Column-Operator-Frame substrate beneath the tools.
The FrameQL manual (v1) The query language against the Manifold, completely.
The reference manual (5e) A distinct manual — the object model, the definition language, the Certificate layer.
The shipped grammar Read before writing a Manifold — every keyword the shipped parser accepts, with exact signatures and examples verified against the released package at build time.

Positions

Positions Positions we hold, stated plainly and linked to their evidence. When the evidence moves, the position moves — with a note.
Never Let Your Agent Touch the Database Breach, bill, and fabrication are one architectural mistake — and they retire together. With the precision × recall 2×2.
The Two Great Sources of Silent Analytical Failure The site edition of the paper — four degrees of freedom, two of them structurally deep, and what that implies about where the defense must live.

Around the corpus

the argument The eight-minute case for why Columna exists, with two live exhibits.
The research corpus The corpus map (v0.2) — how the theory, the proved kernel, the introductions, the positions, the ripples, and the engine fit together, every claim one click from its DOI.
