September 8, 2004 - Middletown, CT - The Library of Congress signed a second contract with Index Data last month for development and consulting services in conjunction with the use of three Index Data Open Source library application software packages: Keystone Digital Library Suite, YAZ Proxy and Zebra.
LC will use the Keystone Digital Library Suite (Keystone Organizer and Keystone Retriever) in a pilot project designed to provide broader access to LC resources that are currently only available to the public through separate HTML interfaces. The Zebra indexing engine will complement the use of Keystone by making some files directly searchable that formerly were not. Index Data developers will also build customized Z39.50/SRU/SRW search and retrieval gateways for each type of resource.
The pilot project is designed to provide federated search services (also called metasearch services) with easy and rapid access to resources such as LC's American Memory collections. The custom-built gateways will translate standard Z39.50/SRU/SRW queries that all federated search systems support into non-Z39.50 search protocols used by various software tools (e.g. inQuery/Aurora, Lucene and MySQL).
LC selected Index Data for this project because of the company's proven expertise in building Z39.50 gateways to structured databases, and because of the company's commitment to an Open Source distribution.
As part of the contract, Index Data will also enhance the Library's YAZ Proxy front-end to its Voyager Integrated Library System databases to support Z39.50/SRU/SRW retrieval of records with holdings, which will then be sent to the searcher in an XML format. The enhancement will subsequently be incorporated into the YAZ Proxy OSS distribution available for free download (and optional installation and support contract) from the Index Data web site.
