Older specifications, on which some of these more recent standards are based, merely contain a brief description of 'identity': "\[a] set of attributes related to an entity," in [@openid:connect]{.title-short.} (OIDC) [@openid:connect]; and "\[the] essence of an entity ... described by one's characteristics," in OASIS's [@oasis:glossary]{.title-short.} (SAML) [@oasis:glossary] -- referencing the Merriam-Webster dictionary. These are far from workable definitions for core specifications around this topic.
