This is good stuff... Is there any schema available that describe the valid response? I can produce one for you if none is available, but I can't find the fully populated document to see the form of "synonyms", "antonyms" or any other map/array that may be returned by the API.

If you do have the schema available please le me know (esobrino@openk.com), or if you like me to give you one based on a fully populated JSON document I will glad to do.

Please continue with this effort.. Eduardo Sobrino
