SAML vocabulary extension for OTTO Draft-01
otto-saml-draft-01
This specification describes a method for packaging information about SAML-based federations, and establishing mechanisms for its validation. It includes term definitions which appear in the current JSON-LD context for the OTTO 1.0 specification.
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

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.
