2000.01 7BD1A39662B54C1691365ADE01366A0A Search Interface Protocols and Specifications en-US LOMv1.0 networked There are several available interface specifications, protocols and APIs for repository search and information retrieval. This document compares key characteristics of these to inform selection or profiling of one or more of these specifications for use within a CORDRA™ implementation or within Federated CORDRA. This is a general CORDRA informational document.

Major alternatives are compared in order to identify common features and variations between approaches. These are then compared to core requirements for CORDRA. As applicable, one or more of these specifications might be selected and profiled to provide a search interface to the registry of a CORDRA implementation or to provide a search interface for Federated CORDRA. This document compares five different specifications used in digital libraries and web search. * SQI [SQI, SQI Sessions, SQI LORI] * SRW/SRU [SRW, CQL, Zing, ZeeRex, Zoom, Z39-50] * OpenSearch [OpenSearch] * Google Web Service API [Google] * OAI-PMH [OAI] LOMv1.0 no LOMv1.0 yes © Copyright, 2005, Some Rights Reserved, Creative Commons License by-nc-sa/2.0, http://creativecommons.org/licenses/by-nc-sa/2.0, 2000.01-7BD1A39662B54C1691365ADE01366A0A.odrl.drel.xml
