Introduction Extensible Resource Identifiers (XRIs) are a way of abstractly identifying a resource independently of any particular concrete representation of it. They are designed to suit Requirements for Uniform Resource Names (URNs), laid out in [RFC1737], even though they are not URNs [RFC2141] themselves. The comprehensive XRI specification includes 3 documents: [XRISyntax], which is the normative technical specification of XRI generic syntax, [XRIResolution], which defines an optional HTTP-based resolution protocol for XRIs, and [XRIMetadata], which defines four namespaces under the XRI global context symbol "$" for common types of identifier metadata. See [XRIIntro] for non-normative description of XRIs and [XRIFaq] for FAQ on XRIs. XRI requirements and glossary are defined in [XRIReq]. [XRISyntax], Section 2.3.1 specifies rules for transforming XRI references to URI [RFC3986] and Internationalized Resource Identifiers (IRIs) [RFC3987] references. It mentions that URIs mapped from XRIs use the "xri" scheme name. It has been noted that this scheme name is not officially registered with IANA, as described in [RFC4395]. This document removes the uncertainty by formal registration of the 'xri' URI scheme. 1.1. Community Consensus The Organization for the Advancement of Structured Information Standards (OASIS) has the Technical Committee (TC), which is responsible for developing and maintaining XRI specifications, - XRI TC. This document has been prepared for this TC and has received its excessive review, which revealed wide consensus of the TC's members. [IMPORTANT: Currently, this document is only a subject for the aforementioned review; the paragraph above actually does not represent TC consensus.] 2. Registration Template for 'xri' URI Scheme This section contains the registration template for 'xri' URI scheme, as required by [RFC4395].

Security Considerations Security considerations for XRIs are discussed in Section 3 of [XRISyntax] and Section 18 of [XRIResolution]. 4. IANA Considerations IANA is asked to register the 'xri' URI scheme using the template of Section 2. 5. References 5.1.
