Function Details

[hide private]

identifierScheme(identifier)

source code

Determine if this identifier is an XRI or URI.

Returns:: "XRI" or "URI"

rootAuthority(xri)

source code

Return the root authority for an XRI.

Example:

   rootAuthority("xri://@example") == "xri://@"

Parameters:

xri (unicode)

Returns: unicode

XRI(xri)

source code

An XRI object allowing comparison of XRI.

Ideally, this would do full normalization and provide comparsion operators as per XRI Syntax. Right now, it just does a bit of canonicalization by ensuring the xri scheme is present.

Parameters:

xri (unicode) - an xri string
