OpenID specifications are developed by OpenID working groups and go through three phases: Drafts, Implementer’s Drafts, and Final Specifications. Implementer’s Drafts and Final Specifications provide intellectual property protections to implementers. Final Specifications are OpenID Foundation standards.
