#yaml

A YAML parser that produces output compatible with unist

Create, edit, and validate scientific metadata against a standard (MIAPPE, ISA, Darwin Core, DiSSCo, ENA, PRIDE, MetaboLights, FAIRDOM-SEEK) from a YAML profile — CLI, web interface, Python API, and MCP server.

🔄 Synchronize projects via yaml/json manifest. Built using `libvcs`.

Powerful, joyful building blocks for modern cloud-native applications.

Zero-boilerplate type-safe Rust configuration library — #[derive(Config)] with TOML/JSON/YAML/INI/.env sources, priority-chain merge, hot reload with canary rollout, field encryption, remote backends (etcd/Consul/Nacos/K8s), and diagnostic CLI

Collaborate on board. Make it living in text.
