"Metasearch, parallel search, federated search, broadcast search, cross-database search, search portal are a familiar part of the information community's vocabulary. They speak to the need for search and retrieval to span multiple databases, sources, platforms, protocols, and vendors at one time. Metasearch services rely on a variety of approaches to search and retrieval including open standards (such as NISO's Z39.50), proprietary API's, and screen scraping. However, the absence of widely supported standards, best practices, and tools makes the metasearch environment less efficient for the system provider, the content provider, and ultimately the end-user.

"In acknowledging the Web as the platform for searching, sharing, aggregating and extending information, librarians need to familiarize themselves with the semantic web (an extension of the current web), learn new tools, techniques and trends. Most importantly for catalogers, they need to educate themselves in RDA (Resource Description and Access) which may soon replace AACR2 and MARC 21 as the new cataloging rules and standards. RDA is a set of guidelines evolved from AACR2 and is constructed on the framework of FRBR (Functional Requirements for Bibliographic Records) and FRAD (Functional Requirements of Authority Data). The application of which is meant to direct the library catalog in providing better access to Web resources. Instead of being a display standard of library catalog using AACR2, RDA is a content standard that attempts to improve the way catalogers describe and present elements, entities and their relationships and roles in the bibliographic world. It is also the intention of RDA to make data in library catalog play a better role in the Web environment. Moreover, RDA is supposedly more flexible and adaptable in that it may be used with many encoding schema such as MODS, MARC, Dublin Core, etc."

"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.

"The University of Calgary's Libraries and Cultural Resources became a beta partner with Serials Solutions' unified discovery service, Summon, in the spring of 2009. Since then it has worked to include metadata from numerous disparate systems in a single index to drive discovery in a Google-like environment. The University of Calgary has examined how MARC and other metadata schemas are mapped into Summon with an eye to ensuring the maximum possible population of index fields representing facets in addition to adhering to the established standards for cross mapping metadata schemas and indexing. The University of Calgary has investigated existing standards and worked closely with the Summon team to create mappings that reflect how MARC and other metadata can ultimately be used in big indexes. Combined with the normalization or collapsing of metadata records representing the same resource into a single metadata-rich record, fully leveraging MARC and other metadata in big indexes should not only level the metadata playing field but make competition between records a non-issue."

"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. "

"MasterKey is a growing and evolving family of tools for building sophisticated information discovery solutions. They can be used individually, or they can be combined together using a shared service-based architecture. Some of the tools have been released by Index Data under OSS (open source software) licenses, whereas others, at this time, are made available exclusively to our customers. To complement the software, Index Data offers a full range of support, consulting, and development services. For businesses, our components are flexible and modular enough to fit into practically any existing software platform. For consortia and larger libraries, we offer an opportunity to create a solution which is uniquely adapted to local needs, while also based on open software components and open standards."

"The Google Search Appliance (GSA) is a black-box system in that you install it, set up your options, and it runs. It is certainly standards-based: it indexes HTML and other popular formats; and the results are typically defined using XML and style sheets. But the options you can customize with regard to data sources, relevance ranking, and extended search (thesaurus, taxonomies, and parametric or faceted search) are somewhat limited. FAST, Autonomy/Verity K2, OmniFind and other traditional enterprise search engines have always been toolkits. You install the software and begin the process of customizing it for your environment. Data in databases or content repositories? No problem. Custom security implementation? Modify the indexing and search methods. Have custom thesauri or existing taxonomies? Plug them in. Need parametric or faceted search results? Small matter of programming - although not much. Want to change the way results are ranked or sorted? Use the native query syntax - for example, FAST Query Language (FQL) or the Verity Query Language (VQL)."

"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. "

"Open Search browser plug-ins are small XML files that reference a template URL which include any parameters for the specified search engine. Open Search browser plug-ins can be created using any search engine that produces a stable, durable URL to deliver results. The Open Search standard is compatible with the Internet Explorer 7 and Firefox 2.x browsers. Full documentation for the standard can be found at: http://www.opensearch.org/"

"RDA sera peut-être le format de catalogage de demain. Basé sur les FRBR et les FRAR, RDA se donne les objectifs suivants : * Fournir un "framework" fiable et souple pour décrire à la fois le contenu et les aspects techniques de tous types de ressources et de documents * Etre compatible avec des principes, modèles et standards internationaux * Etre utilisable hors de la communauté des bibliothèques, et que des communautés variées puissent l'adapter à leurs besoins spécifiques. "

"The Google Search Appliance XHTML Stylesheet defines a user interface for your Google Search Appliance that conforms to modern web standards including XHTML 1.0 Strict, XHTML Mobile Profile (XHTML-MP) and CSS 2.1. It generates well-formed, valid markup and is accessible in a variety of browsers and presentation modes. "

"In 2007-2008, the DLF convened a Task Group to recommend standard interfaces for integrating the data and services of the Integrated Library System (ILS) with new applications supporting user discovery. This page gives access to the group's recommendation, related materials, and information on followup activities."

"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). "
