WS-I Basic Profile Version 1.1

WS-I Basic Profile Version 1.1 (WS-I BP 1.1) is a set of non-proprietary Web services specifications, along with clarifications and amendments to those specifications, which together promote interoperability between different implementations of Web services.

The WS-I BP 1.1 is derived from Basic Profile Version 1.0 by incorporating its published errata and separating out the requirements that relate to the serialization of envelopes and their representation in messages. These requirements are now part of the Simple SOAP Binding Profile Version 1.0.

To summarize, the WS-I Basic Profile Version 1.0 has now been split into two separately published profiles. These are: Together, these two Profiles supersede the WS-I Basic Profile Version 1.0.

The reason for this separation is to enable the Basic Profile 1.1 to be composed with any profile that specifies envelope serialization, including the Simple SOAP Binding Profile 1.0.

The specification for WS-I BP 1.1 is published by the Web Services Interoperability Organization (WS-I), and can be found at WS-I Basic Profile Version 1.1.
