Editing WS-I Basic Profile (section)

{{Short description|Interoperability guidance for core web services specifications}}
The '''WS-I Basic Profile''' (official abbreviation is BP), a specification from the [[Web Services Interoperability]] industry consortium (WS-I), provides [[interoperability]] guidance for core [[Web Services]] specifications such as [[SOAP]], [[Web Services Description Language|WSDL]], and [[UDDI]]. The profile uses [[Web Services Description Language]] (WSDL) to enable the description of services as sets of endpoints operating on messages.

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.
