PEER is a lightweight, global registrar for Security Assertion Markup Language (SAML) metadata.
PEER offers a trusted registry that relies on domain validation only to assess whether a service can register any given entity metadata. PEER metadata can be consumed by any federation. PEER is intended as a focused activity to support international federated access, complementing national identity federations and inter-federation.
Registrants must be aware that they are making their metadata available for publication without constraint and that registered metadata will be publicly available to all consumers. Consumers may constrain what information they import from the system.
