Yana: Yet another node authority!
You didn't have one or you wanted another node authority.
Yana strives to offer a simple and basic node metadata service.
The basic concept of Yana is a "Node" which represents an object in a network. Nodes are defined in terms of a "NodeType" which defines a set of attributes about a node.
The primary interface to Yana, is its WebAPI but there is also a rudimentary HTML-based graphical interface.
