| + | #REDIRECT [[EntityId]] |
| − | This page defines a Higgins [[NodeIdDataRange]].
| + | |
| − | | + | |
| − | == Definition ==
| + | |
| − | * A [[NodeIdDataRange]] is a kind of URI [[Data Range]].
| + | |
| − | * A [[NodeIdDataRange]] MAY be absolute or relative:
| + | |
| − | ** An absolute [[NodeIdDataRange]] MUST uniquely identify both a [[Context]] and a specific [[Node]] within that [[Context]].
| + | |
| − | ** A relative [[NodeIdDataRange]] MUST uniquely identify a [[Node]] within a given [[Context]].
| + | |
| − | * A [[NodeIdDataRange]] MUST conform to the ABNF defined below.
| + | |
| − | | + | |
| − | == ABNF ==
| + | |
| − | The following [http://en.wikipedia.org/wiki/Augmented_Backus-Naur_form ABNF] defines the syntax of a Higgins [[NodeIdDataRange]]. Rules not defined in this ABNF are defined in either:
| + | |
| − | * The [[ContextIdDataRange]] definition, or
| + | |
| − | * The [http://wiki.oasis-open.org/xri/XriCd02/Xri2dot0Abnf ABNF for XRI 2.0] (which includes the IRI ABNF from [http://www.ietf.org/rfc/rfc3987.txt RFC 3987]).
| + | |
| − | | + | |
| − | NodeIdDataRange = 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 [http://www.w3.org/TR/2007/WD-cooluris-20071217/ Cool URIs] defined by the [http://www.w3.org/ W3C].
| + | |
| − | * The '''AbsoluteNodeXRI''' form is an [http://en.wikipedia.org/wiki/XRI XRI] as defined by [http://wiki.oasis-open.org/xri/XriCd02/Xri2dot0Abnf XRI Syntax 2.0].
| + | |
| − | * See [[Context Discovery]] for rules defining resolution of an instance of a [[NodeIdDataRange]].
| + | |
| − | | + | |
| − | == Relationship to OpenID ==
| + | |
| − | * An [http://openid.net/specs/openid-authentication-2_0.html OpenID 2.0] compliant URL or XRI may serve as an absolute [[NodeIdDataRange]]. See [[ContextIdDataRange]] for details.
