The Web Services Interoperability Organization announced that three of its Profiles have been published by the International Organization for Standardization as ISO/IEC 29361, 29362 and 29363. WS-I's Basic Profile 1.1 provides interoperability guidance for a core set of non-proprietary Web services specifications, such as SOAP, WSDL and UDDI, along with interoperability-promoting clarifications and amendments to those specifications; Attachments Profile 1.0 complements the Basic Profile to add support for interoperable SOAP Messages with attachments-based Web services; and the Simple SOAP Binding Profile 1.0 consists of the Basic Profile requirements related to the serialization of the envelope and its representation in the message.
