"SRU (Search/Retrieve via URL) et SRW (Search/Retrieve Web service) sont deux protocoles qui, succédant à Z3950, en constituent une évolution, et ce vers les technologies web, via les webservices. Maintenus par la Bibliothèque du Congrès, et destinés à faciliter la recherche sur Internet, ils se fondent sur le langage CQL (Common Query Language, standard de syntaxe de requête), qui présente l'avantage d'une (relative) lisibilité. SRU/SRW spécifient tout à la fois la syntaxe des requêtes, et celle des réponses données à ces requêtes. SRU/SRW permettent d'interroger simplement, via le protocole http du web, des bases de données jusqu'alors cachées ou plus difficilement accessibles. La version 1.1 de SRU a été publiée en février 2004, et devrait être suivie d'une version 1.2 actuellement en cours de développement. "

"Le protocole d'échange de métadonnées SRU (Search/Retrieval via URL) est l'équivalent fonctionnel du protocole Z39.50 en s'adaptant aux standards technologiques du web (protocole http et format xml). "

"For more than 15 years, Index Data has built technologies and solutions in support of searching. Our customers and partners include national libraries and consortia, government agencies, and commercial companies. Our business is to seek out the most challenging problems in the area of metasearching and large-scale content indexing and searching, and to engineer industrial-strength tools to help people solve those problems. We have been active participants in and contributors to the international standards communities in our field since the very beginning. Our open-source protocol implementations are the most widely used in the industry and have had significant impact on both the evolution and penetration of international standards like Z39.50 and SRU. Because of our long history in this area, and our focus on building flexible, reusable tools for developers and organizations, our partners can focus their attention on adding value and on creating compelling user experiences.

"Not all library content can be exposed as HTML pages for harvesting by search engines such as Google and Yahoo!. If a library instead exposes its content through a local search interface, that content can then be found by users of metasearch engines such as A9 and Vivísimo. The functionality provided by the local search engine will affect the functionality of the metasearch engine and the findability of the library's content. This paper describes that situation and some emerging standards in the metasearch arena that choose different balance points between functionality and ease of implementation. "
