Executive Summary (This is a document excerpt)

Web services adoption continues, but it is taking a long time to work out all the specifications and standards. According to data from recent Forrester surveys, among the core Web services messaging specifications, SOAP and WSDL 1.1 have strong user support and near-universal vendor support. WS-I Basic Profile and SOAP with Attachments have strong vendor support, and users are beginning to adopt WS-I Basic Profile. Forrester observes a persistent, though not widely noted, level of industry concern about SOAP performance, yet users currently have little interest in specifications for optimized SOAP messaging. About one-third of vendors will support optimized SOAP messaging by 2007. Several additional core messaging specifications have yet to gain broad support from either vendors or users.
