Zombie Node Format

Zombie Node Format (znf) is the configuration format for zombie nodes.

The format describes nodes and their properties. The main purpose of this module is to provide tools and a validation schema for working with zombie nodes. It includes a JSON schema validator for the format.

The format is extensible so other modules can expand it's capabilities and semantics.
