Design principle of making every identifier carry enough qualification to be understood on its own — removing the need for surrounding context (type, nesting, documentation) to disambiguate. In Pathom/EQL this is achieved via namespaced keywords. Context-free identifiers unlock query flattening (since attributes no longer need to live under a parent scope to be meaningful) and enable cross-service integration by aliasing one service's id to another's (e.g. treating SpaceX's YouTube-ID field as the same thing as :youtube.video/id).
