OGDL (Ordered Graph Data Language), is a "structured textual format that represents information in the form of graphs, where the nodes are strings and the arcs or edges are spaces or indentation."
Like XML, but unlike JSON and YAML, OGDL includes a schema notation and path traversal notation. There is also a binary representation.
Example network eth0 ip 192.168.0.10 mask 255.255.255.0
hostname crispin
