SRW defines a web service for searching databases containing metadata and objects, both text and non-text. The SRW Initiative builds on Z39.50 along with web technologies. Building on Z39.50 semantics enables the creation of gateways to existing Z39.50 systems; web technologies reduce the barriers to new information providers allowing them to make their resources available via a standard search and retrieve service. SRU, Search and Retrieve URL Service, is a companion service to SRW, whose primary difference is its access mechanism. This has been added to Deep Web Research Subject Tracer™ Information Blog.
