OASIS created the Search Web Services Technical Committee in 2008 to "define search and retrieval web services based on current technologies, most notably, Search and Retrieval via URL (SRU), Contextual Query Language (CQL), and OpenSearch." The group will also be producing revisions to SRU and CQL. SRU now incorporates its sister protocol, Search and Retrieve via Web Service (SRW), as a variant. Both SRU and SRW were developed as next generation internet-capable extensions of Z39.50.
