ontology2dot

ontology2dot - create dot graphs from YAML ontology documents

installation: npm install -g ontology2dot

usage: ontology2dot < ontology.yaml > output.dot

or to add inherited edges: ontology2dot --children < ontology.yaml > output.dot

as a module:

var o2d = require("ontology2dot");

//read yaml from stream, work out inherited, result as string in callback.
o2d.fromStream(process.stdin, {children: true}, function(result){
    console.warn("finished!");
    console.log(result);
});

//from a yaml string.
var dot = o2d.fromString(yamlString);

//from decoded yaml object
o2d.fromObject(ontologyObject, {stream: process})

works well with Graphviz, e.g.

ontology2dot --children < ontology.yaml | dot -Tsvg > ontology.svg
