OpenWF Adoption and Conformance Testing

OpenWF Adopter Login

Any company may freely use the publicly released OpenWF specification to create a product, but implementations of the OpenWF API must be tested for conformance in the Khronos OpenWF Adopters program before the OpenWF name or logo may be used in association with an implementation of the API.

Implementers may join the Khronos OpenWF Adopters Program which enables them to download and execute the OpenWF conformance tests and upload the results for peer review within Khronos.  If the implementation successfully passes the tests, the Adopter is granted a royalty-free trademark license to use the OpenWF name and logo in association with that implementation - and they can refer to the implementation as being OpenWF conformant or OpenWF compliant.

Benefits of the OpenWF Adopters program:

  • Access to the OpenWF 1.0 conformance test source code
  • Participation in the OpenWF Adopters technical Mailing list - a private priority channel for two-way interaction with the OpenWF working group over the specification and conformance tests
  • Conformant products may use the OpenWF name and logo
  • Company listing on the Adopting Members and Conformant Products pages
