    It includes interfaces that support DSpace's Lucene implementation and OCLC's Pears and Newton databases.
    <P>SRW is a Web Service for searching text databases; SRU provides the same functionality as SRW, but is URL based. They both support the same kind of search and retrieval functionality provided by Z39.50.</P>
<P>Why use them?<BR>Web Services are becoming part of the standard toolkit for implementors.&nbsp; URL's are even simpler; responses are just XML records.&nbsp; This could well be the interface to repositories that all those architecture diagrams call for.</P>
<P>User interfaces can be created using XSL stylesheets, allowing browsers to support rich interfaces with no special code at the server end and no client code other than the browser.</P>
<P>What are we providing?<BR>We've built an SRW/SRU (or SRW/U) server.&nbsp; It acts as an interface to local databases.&nbsp; The local databases it currently supports are Lucene, Pears and Newton.&nbsp; Lucene is the database underlying DSpace and Pears and Newton are used by OCLC's SiteSearch.</P>
