onomy.org is a site where you can create and share taxonomies, folksonomies, and other forms of controlled vocabularies for use on the semantic web. To get started, log in above using a federated ID from one of the services listed. Then you'll be able to create new onomies, invite others to work on them with you, and publish them as RDF, JSON, and HTML. What you do with your published onomy is up to you! Import it into an application, link to it from a web service, or just use it for reference. When you publish a version of your onomy a permanent link is created that will always reference that version of it. If you want to keep working on it, go ahead; you can always publish another version later.
