Welcome to Knoodl!

Knoodl is sort of an ontology editor, registry/repository, and wiki all rolled into an easy to use online application. There's never been anything quite like it.

  • Upload an ontology you already have, or build one from scratch.
  • Add rich documentation with wikitext, so that other people can understand what your ontology is about.
  • Work with other people on the same vocabulary, at the same time
  • Find and download other ontologies and use them in semantic applications.

What's Different about Knoodl?

Describing the terminology and semantics that you use in a particular domain requires collaboration: there are the people responsible for creating the vocabulary, those who review it, and those who will refer to it. Knoodl was created from the ground up to allow all these people to collaborate. Plus, there's nothing to download, nothing to install, nothing to configure and nothing to maintain. And it's free! All you need is a web browser and an Internet connection.

Check out our Screencast!

We have a new screencast that is a great introduction to Knoodl and a great way to see it in action.

Where do I start?

If you're new, take the tour and see how to get started. Then, dive in and check out some of the example vocabularies, and see what vocabularies people have already uploaded. Better yet, register for an account, create or join a community, and start contributing!

New Features!

We've recently added several great new features to Knoodl. Contributors to a community will find several new actions available, including some useful ones for vocabularies (including 'Create new class' and 'Create new property'). Additionally, each community can now control the privileges of each community member, of non-members, and of anonymous members (those users that have not logged in). For more information, see the permissions documentation.
