Introduction

This page defines a Higgins NodeIdDatatype.

Definition

ABNF

The following ABNF defines the syntax of a Higgins NodeIdDatatype. Rules not defined in this ABNF are defined in either:

NodeIdDatatype     = AbsoluteNodeId / RelativeNodeId
AbsoluteNodeId     = AbsoluteNodeURI / AbsoluteNodeXRI
AbsoluteNodeURI    = ContextURI [ "#" ifragment ]
AbsoluteNodeXRI    = ContextXRI [ "//" xri-segment ]
RelativeNodeId     = ifragment / xri-segment

Notes

  • In an AbsoluteNodeId, a RelativeNodeId is optional when the Context identified by the ContextURI or ContextXRI contains exactly one Node.
  • The AbsoluteNodeURI form is consistent with one of the two proposed forms of Cool URIs defined by the W3C.
  • The AbsoluteNodeXRI form is an XRI as defined by XRI Syntax 2.0.
  • See Context Discovery for rules defining resolution of an instance of a NodeIdDatatype.

HXRIs

A HXRI ("HTTP XRI") is an XRI that uses an HXRI proxy resolver prefix. "xri.net" is a public HXRI proxy resolver operated by XDI.org. All others are examples.
