    The NASA Technical Report Server (NTRS), a World Wide Web (WWW) report distribution service, has been modified to allow parallel database queries, significantly decreasing user access time by an average factor of 2.3, access from clients behind firewalls and/or proxies which truncate excessively long Uniform Resource Locators (URL's), access to non-Wide Area Information Server (WAIS) databases, and compatibility with the Z39-50.3 protocol

    Lyceum: A Multi-Protocol Digital Library Gateway

    Get PDF
    Lyceum is a prototype scalable query gateway that provides a logically central interface to multi-protocol and physically distributed, digital libraries of scientific and technical information. Lyceum processes queries to multiple syntactically distinct search engines used by various distributed information servers from a single logically central interface without modification of the remote search engines. A working prototype (http://www.larc.nasa.gov/lyceum/) demonstrates the capabilities, potentials, and advantages of this type of meta-search engine by providing access to over 50 servers covering over 20 disciplines

    The NASA Technical Report Server (NTRS), a World Wide Web report distribution NASA technical publications service, is modified for performance enhancement, greater protocol support, and human interface optimization. Results include: Parallel database queries, significantly decreasing user access times by an average factor of 2.3; access from clients behind firewalls and/ or proxies which truncate excessively long Uniform Resource Locators (URLs); access to non-Wide Area Information Server (WAIS) databases and compatibility with the 239-50.3 protocol; and a streamlined user interface

Introduction Internet document and information archival, indexing, and distribution is typically embodied in widely heterogeneous and distributed information servers, employing search engines with user interfaces and query syntax that vary significantly. The incompatibility and noninteroperability between search engines and the lack of a common and unified interface betw..
