    OCLC researcher Ralph LeVan helps create the next generation of Z39.50 software
    Called Search and Retrieve Web/Search and Retrieve URLs (SRW/U), the new service uses the basic Z39.50 features in combination with Web technology.

    <P>Mr. LeVan has written an open source version of the software, which libraries and other organizations can download at no charge from the OCLC Web site.</P>
<P>"The SRW/U initiative is part of an international collaborative effort to develop a standard, web-based, text-searching interface," says Mr. LeVan.&nbsp; "It is 'plumbing' that uses different mechanisms for transmitting requests and presenting data, and it draws heavily on the abstract models and functionality of Z39.50, but removes much of the complexity."</P>
<P>SRW/U brings the Z39.50 experience to the Web community using tools familiar to its members—Web Service Description Language, Simple Object Access Protocol and Extensible Markup Language.&nbsp; It provides a basis for the Web community to solve some of their searching problems, and the potential for Web applications to access Z39.50 resources.</P>
<P>"Developing SRW interfaces to data repositories is significantly easier than for Z39.50," LeVan says. "This activity is a great opportunity to leverage library experience with text searching in local and distributed databases, and to provide increased interoperability with other communities on the Web."</P>
