The official specification repository for KDL, a small document language with XML-like node semantics usable as both a serialization format and a configuration language, like JSON, YAML, or XML. It includes the finalized KDL 2.0.0 spec plus companion specs for a KDL Query Language and a KDL Schema Language.

Use cases

• find a human-friendly alternative to yaml or json for config files
• read the kdl document language specification
• learn kdl syntax for configuration files
• implement a kdl parser for my language
• migrate from kdl 1.0 to kdl 2.0
• query kdl documents with css-like selectors
• define schemas for kdl documents

When to choose

• you need the authoritative reference for implementing or using KDL
• you want a config/serialization format that is pleasant to hand-write
• you need formal specs for querying or validating KDL documents

When to avoid

• you need a ready-to-use parser library rather than a specification
• you need a battle-tested format with broad ecosystem tooling like YAML or TOML
• you expect frequent language changes, since KDL 2.0.0 is finalized
