WS-I Basic Profile

<p>The WS-I Basic Profile (official abbreviation is BP), a specification from the <a href="/facts/Web_Services_Interoperability/J2AtdqSq">Web Services Interoperability</a> industry consortium (WS-I), provides <a href="/facts/Interoperability/7WgqUbXU">interoperability</a> guidance for core <a href="/facts/Web_Services/qxrwqB3D">Web Services</a> specifications such as <a href="/facts/SOAP/vXlAMnjp">SOAP</a>, <a href="/facts/Web_Services_Description_Language/tQPIot4A">WSDL</a>, and <a href="/facts/UDDI/I59oVM1h">UDDI</a>. The profile uses <a href="/facts/Web_Services_Description_Language/tQPIot4A">Web Services Description Language</a> (WSDL) to enable the description of services as sets of endpoints operating on messages.
</p><p>To understand the importance of WSI-BP, note that it defines a much narrower set of valid services than the full WSDL or SOAP schema. Many common platforms (listed below) support WSI-BP but do not support services outside of it. Compare the WSDL 1.1 specification to the subset permitted in WSI-BP.  Also note that WSI-BP generally narrows the SOAP specification.  There is a notable exception where WSI expands on the SOAP standard, and that is in adding xml:lang attribute on fault elements.
