JSONSelect is EXPERIMENTAL, ALPHA, etc.

JSONSelect defines a selector language similar to CSS intended for JSON documents. For an introduction to the project see jsonselect.org or the documentation.

Project Overview

JSONSelect is an attempt to create a selector language similar to CSS for JSON objects. A couple key goals of the project's include:

  • intuitive - JSONSelect is meant to feel like CSS, meaning a developers with an understanding of CSS can probably guess most of the syntax.
  • expressive - As JSONSelect evolves, it will include more of the most popular constructs from the CSS spec and popular implementations (like sizzle). A successful result will be a good balance of simplicity and power.
  • language independence - The project will avoid features which are unnecessarily tied to a particular implementation language.
  • incremental adoption - JSONSelect features are broken in to conformance levels, to make it easier to build basic support and to allow incremental stabilization of the language.
  • efficient - As many constructs of the language as possible will be able to be evaluated in a single document traversal. This allows for efficient stream filtering.

JSONSelect should make common operations easy, complex operations possible, but haughtily ignore weird shit.
