The IESG has approved a request to register the "application/samlmetadata+xml" MIME media type in the standards tree. This media type is a product of the Organization for the Advancement of Structured Information Systems (OASIS). The IESG contact persons are Ted Hardie and Scott Hollenbeck. MIME media type name: application MIME subtype name: samlmetadata+xml Required parameters: none Optional parameters: charset Same as charset parameter of application/xml [RFC3023]. Encoding considerations: Same as for application/xml [RFC3023]. Security considerations: Per their specification, samlmetadata+xml typed objects do not contain executable content. However, these objects are XML-based [XML], and thus they have all of the general security considerations presented in section 10 of [RFC3023]. SAML metadata [SAMLv2Meta] contains information whose integrity and authenticity is important - identity provider and service provider public keys and endpoint addresses, for example. To counter potential issues, the publisher may sign samlmetadata+xml typed objects. Any such signature should be verified by the recipient of the data - both as a valid signature, and as being the signature of the publisher. Additionally, various of the publication protocols, e.g. HTTP-over-TLS/SSL, offer means for ensuring the authenticity of the publishing party and for protecting the metadata in transit. [SAMLv2Meta] also defines prescriptive metadata caching directives, as well as guidance on handling HTTPS redirects, trust processing, server authentication, and related items. For a more detailed discussion of SAML v2.0 metadata and its security considerations, please see [SAMLv2Meta]. For a discussion of overall SAML v2.0 security considerations and specific security-related design features, please refer to the SAML v2.0 specifications listed in the below bibliography. The specifications containing security-specific information are explicitly listed. Interoperability considerations: SAML v2.0 metadata explicitly supports identifying the protocols and versions supported by the identified entities. For example, an identity provider entity can be denoted as supporting SAML v2.0, SAML v1.1 [SAMLv1.1], Liberty ID-FF 1.2 [LAPFF], or even other protocols if they are unambiguously identifiable via URI [RFC2396]. This protocol support information is conveyed via the protocolSupportEnumeration attribute of metadata objects of the RoleDescriptorType. Published specification: [SAMLv2Meta] explicitly specifies use of the application/samlmetadata+xml MIME media type. Applications which use this media type: Potentially any application implementing SAML v2.0, as well as those applications implementing specifications based on SAML, e.g. those available from the Liberty Alliance [LAP]. Additional information: Magic number(s): In general, the same as for application/xml [RFC3023]. In particular, the XML root element of the returned object will be one of <md:EntityDescriptor>, <md:AffiliationDescriptor>, or <md:EntitiesDescriptor>. where "md" maps to the SAML v2.0 metadata namespace: urn:oasis:names:tc:SAML:2.0:metadata File extension(s): none Macintosh File Type Code(s): none Person & email address to contact for further information: This registration is made on behalf of the OASIS Security Services Technical Committee (SSTC) Please refer to the SSTC website for current information on committee chairperson(s) and their contact addresses: http://www.oasis-open.org/committees/security/. Committee members should submit comments and potential errata to the securityservices at lists.oasis-open.org list. Others should submit them by filling out the web form located at http://www.oasis-open.org/committees/comments/form.php?wg_abbrev=s Additionally, the SAML developer community email distribution list, saml-dev at lists.oasis-open.org, may be employed to discuss usage of the application/samlmetadata+xml MIME media type. The "saml-dev" mailing list is publicly archived here: http://lists.oasis-open.org/archives/saml-dev/. To post to the "saml-dev" mailing list, one must subscribe to it. To subscribe, send a message with the single word "subscribe" in the message body, to: saml-dev-request at lists.oasis-open.org. Intended usage: COMMON Author/Change controller: The SAML specification sets are a work product of the OASIS Security Services Technical Committee (SSTC). OASIS and the SSTC have change control over the SAML specification sets. Bibliography [LAP] "Liberty Alliance Project".
