The uri is a Node resource identifier, containing all necessary parts needed to make a djedi node request.

[scheme] :// [namespace] @ [path] . [extension] # [version]
The scheme uri part sets the scope to look within for the given node path.
Possible schemes:
Internationalization scope; defining languages
Local scope; defining regions or flavors, not affected by language
Global scope; defining global non namespaced uris
Each scheme contains at least one namespace, for example the i18n scheme uses the namespace as a locale, determining which language to use.
The path is a unique node key within the given namespace and scheme.
The extension resolves which plugin to use for content management.
Nodes supports revisioning, and the version part represents a version number or string.
