Reference Pages

Spec Excerpts

The following pages are copies of selected key portions of the XRI specifications to make them easy to find/load.

Archival Pages

The pages below are no longer active and are listed primarily for archival purposes.

XRI 2.0 Specification Suite -- Management & Development

XRI 2.0 Spec Suite Documentation (Non-Normative)

The TC plans to publish documentation for the XRI 2.0 suite of specifications as a whole. The following wiki pages are being used to manage these deliverables.

• XriCd02/XriTwoCoreMessages is where TC members are developing the core messages for the XRI 2.0 suite.

• XriCd02/XriTwoPresentation is the cover page for an XRI 2.0 presentation.

• XriCd02/XriTwoWhitePaper is the cover page for an XRI 2.0 white paper.

• The XRI 2.0 FAQ is currently in HTML but is being adapted for wiki editing.

XRI Resolution 2.0

This is the final specification in the XRI 2.0 cycle. It is now at Committee Draft 03 status. Future work will be part of the XRI 3.0 cycle (see above).

The following pages are all archival.

• XriTwo/ResolutionCd03 contained the action items for producing Committee Draft 03.

• Xri2Cd02/ResWorkingDraft11 tracked all proposed issues, revisions, and corrections to XRI Resolution 2.0 Working Draft 10.

• XriCd02/SepSelection (issue #10) documents in pseudocode the service endpoint selecton (SEP) rules.

• XriCd02/CanonicalIdVerification (issue #21) documents new CanonicalID verification parameter and processing rules.

• XriCd02/ServiceRefs (issue #37) is a proposal to support refs at the service level to provide XRDS authors more direct control over physical distribution of XRDS documents.

• XriCd02/XrdsDiscoveryFromHttpUris (issue #3) is the proposed text for the new section 8 that will incorporate the Yadis specification for discovery of XRDS documents from HTTP URIs.

• XriCd02/SynonymSemantics is a proposal for synonym handling.

• XriCd02/RefProcessing is a revised proposal for ref processing.

• XriCd02/ConformanceSection is a draft of the Conformance Section of the spec.

XRI 2.1

The following pages were originally used to discuss a proposed XRI Syntax 2.1 specification. It was subsequently decided that this work should become XRI Syntax 3.0.

• XriCd02/RefactorDiscussion

• XriCd02/XriSyntax2dot1 tracks all proposed issues, revisions, and corrections to the current XRI Syntax 2.0 Committee Specification that will be incorporated into Working Draft 01 of XRI Syntax 3.0.

• XriCd02/Xri2dot1Formats contains proposals for several new XRI forms.

• XriCd02/DirectConcatenation documents a key new proposed feature of XRI Syntax 3.0 and shows how it works with XRI resolution.

• XriCd02/EqualsAtSocialVulnerability discusses possible social attacks on concatenation of = and @ names and proposed solutions.

Outdated Pages The following pages remain listed for reference but have been superceded by the pages above.

• XriCd02/GlobalXrefs, XriCd02/GlobalSubsegments, XriCd02/CompactSyntax -- all replaced by XriCd02/DirectConcatenation.

• XriCd02/ParseTreeExamples - replaced by replaced by XriCd02/DirectConcatenation.

• XriCd02/NormalizationPrinciplesAndPolicies - replaced by XriCd02/DirectConcatenation.

XRI 3.0 Early Planning

The following proposals for XRI Syntax 3.0 were drafted in 2007 prior to the OASIS Standard vote on XRI 2.0, the W3C TAG discussions, and the XRI-as-relative-URI proposal (see links above). All of these are or have been refactored into new proposals for XRI 3.0.

• XriThree/SyntaxOutline is the draft outline for version 3.0 of the XRI Syntax Specification.

• XriThree/CompactSyntaxProposal contains an alternate proposal for version 3.0 of the XRI Syntax Specification.

• XriThree/DollarAndPlusDictionaries discusses the differences and similarities between the \$ and + dictionary spaces.

• XriThree/FormsAndTransformations contains the proposed XRI 3.0 "transformation ladder".

XRI Dictionary

The status of this specification is currently undecided. The previous current working draft is XRI Metadata 2.0 Working Draft 09.

• XriCd02/DictionaryDraft01 tracks all proposed issues, revisions, and corrections for the new XRI \$ Dictionary 2.0 specification that replaces XRI 2.0 Metadata Specification Committee Draft 01. (The former issues page for XRI Metadata 2.0 is at Xri2Cd02/MetadataChanges.)

• XriCd02/DictionaryStructure is the draft outline of the spec.
