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 a host on the network. Information about a node can be defined using an "Attribute", a simple name/value pair. The concept of "Tag" provides a method to match Nodes based on a symbolic name.
The primary interface to Yana, is its WebAPI but there is also a rudimentary HTML-based graphical interface.
