The Open Trust Taxonomy for Federation Operators ("OTTO") defines an extension mechanism to allow the community to add functionality in a community compatible way. This specification was developed to enable OTTO federations to support SAML-based identity services, and defines all the terms used in the JSON-LD context file which the extension covers.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
