What do OpenID, Higgins, i-names, and XDI have in common?
They all use two new OASIS technologies you may not even have heard of yet.
How did these specifications already become key building blocks of the Internet identity layer? What problems do they solve? Where do they fit with the work of other OASIS Technical Committees?
Explicit syntax for reassignable and persistent identifiers
Global context symbols Cross-references for
identifier reuse across contexts
Flexible delegation at all levels of hierarchy
Lossless transformation into IRI and URI forms
XRI Resolution 2.0 HTTP(S)-based
resolution protocol XRDS: simple XML
discovery document format
Synonym management and verification
Service endpoint selection logic
Redirect and Ref processing
Why have XRI and XRDS already become key building blocks of the Internet identity layer?
Not only have XRI and XRDS become an integral part of OpenID 2.0, but the XRI technical community is now a strong part of the OpenID community.
— Bill Washburn Executive Director, OpenID Foundation
XRI and XRDS have become essential elements of the Higgins Project. Without them, we couldn’t fully implement the abstract data model that is the heart of Higgins and the key to user-controlled identity and data sharing.
Public Key Infrastructure (PKI) AdoptionAdvancing the use of digital certificates as a foundation for managing access to network resources and conducting electronic transactions
Conclusion
Abstract structured identifiers offer 3 key features for the Internet identity layer Simple, safe, strong identifiers Simple, extensible, secure service discovery Interoperability between multiple identity
protocols and frameworks XRI and XRDS are building blocks

Q&A
What is the relationship of XRI to URNs?
Uniform Resource Names are specified by IETF RFC 2141
They are persistent (non-recyclable) identifiers
XRI combines both URNs and HFNs (human-friendly names) in one syntax and resolution protocol
What is the relationship of XRI to the Handle System?
Handle is a persistent object identifier system developed by CNRI
Specified in RFCs 3650, 3651, 3652 Handle does not include HFNs or other
structured identifier features of XRI Handle does not use XML or HTTP for
resolution
Does XRI introduce new Internet namespaces?
Yes. Although it can describe and reuse many types of existing identifiers, it also includes four formal namespaces at the XRI level of identification
= for personal identifiers
@ for organizational identifiers
+ for generic tags
$ for specific tags
Does the XRI TC specify public registry services?
No, the scope of the XRI TC is limited to the technical specifications for XRI and specified XRIs (the $ space)
XDI.org, a member of the XRI TC, offers public XRI registry services
XDI.org is a completely separate non-profit organization
What IPR applies to XRI and XRDS? The TC operates under the OASIS “RF
on Limited Terms” mode (standard royalty-free terms)
This has been mandatory from the TC’s original charter
XDI.org made the initial contribution of IPR for what was then called XNS when the TC was formed in 2003
How does Higgins use XRI and XRDS? Higgins uses an abstract data model to
access data in different contexts (distributed repositories)
XRI is used for addressing contexts and entities within contexts
XRDS is used to resolve the metadata a Higgins component needs to open a Higgins context
What open source implementions of XRI and XRDS are available?
