The ID-WSF stack was developed by the Liberty Alliance. The first release, ID-WSF 1.0 (and subsequent 1.1 and 1.2) were
released in 2003. ID-WSF1 was interoperability tested[1] among
several vendor implementations, which received certification from the Liberty Alliance.
However, the first version of ID-WSF was not widely adopted. Perhaps the only significant adoption was by France Telecom
and the French government's Mon Service Public. Some adoption happened in Japan as well. Liberty Alliance proceeded
to create an improved version, the ID-WSF 2.0 in 2006, which included harmonization with certain WS-* technologies,
such as WS-Addressing and WS-Security. These changes were vigorously, and successfully, lobbied by Conor Cahill
of AOL (at the time). ID-WSF 2.0 interoperability certification was participated by several major league vendors, as well
as by startups and open source projects.[2]
Since then, ID-WSF 2.0 has become the only widely accepted interoperable profile of WS-* technologies. Its strength
is essentially in narrow focus where tight enough profile for interoperability was specified. ID-WSF 2.0 interoperability
certification by Liberty Alliance was accomplished by several vendors, including some open source.
ID-WSF 2.0 has been adopted as standards base by the Finnish e-government project and by the European Commission FP7 project TAS3.
