OmnistOne data model, many formats.

Read, validate, and write JSON, YAML, TOML, XML, and OML through one canonical Document and Schema model.

One Document model

A Document is a tree of ordered, labeled edges. The same Document represents JSON, YAML, TOML, XML, and OML -- Omnist's own zero-adjustment native format.

One Schema model

Named record definitions with cardinality-bound fields, each exactly one fixed scalar or a reference to another record -- no open-ended composition.

Compare and infer

Validate a Document against a Schema, check backward compatibility between two schemas, or infer a schema from example documents.
