 Description
 ==========
-WIDOCO helps you publish and create an enriched and customized documentation of your ontology, by following a series of steps in a wizard. We extend the LODE framework by Silvio Peroni to describe the classes, properties and data properties of the ontology, the OOPS! webservice by María Poveda to print an evaluation and the Licensius service by Victor Rodriguez Doncel to determine the license URI and title being used. In addition, we use WebVowl to visualize the ontology and have extended Bubastis to show a complete changelog between different versions of your ontology.
