Info URIs for SRU

About the 'info' identifier scheme (via Standard Disclaimer for External Links)

SRU defines a number of object classes; objects are identified by URIs. Some identifiers are 'http:' URIs, others are 'info:' URIs. (There are various authorities assigning these URIs and there is no specific rule prescribing what URI scheme is to be used; the authority that defines a URI decides which scheme.) This page describes 'info:' URIs for SRU.

Syntax of an SRU 'info' URI

An SRW 'info:' URI is of the form

"info:srw/<object type>/<authority>/<identifier>"
