Slot: format¶

Concrete serialization of the artifact, as a lowercase token: the file extension the artifact is written with, without the leading dot (png, pdf, svg, csv, parquet, json, fits, hdf5, html, md). Where type says what the output is (figure, table, data), format says how it is encoded, so consumers can render, diff, or open it without inspecting the file.

The value space is deliberately open — any lowercase token matching the pattern is legal, so formats specific to a field (asdf, zarr, nc) need no schema change.

Recommended, not required, in 0.0.x: validators warn when it is missing. It becomes required for non-aliased Outputs in 0.1.0. Forbidden when from is set (inherited from the source).
