Everyone is welcome to join WS-I and help advance Best Practices for Web services interoperability. The only requirement for participation is membership in OASIS, the international open standards consortium.
How to join
If you already participate in OASIS or are employed by an OASIS member organization, getting involved in WS-I is easy and will incur no additional dues.
If you are not currently an OASIS member, getting involved in WS-I is still easy. OASIS offers a range of membership dues and benefits to enable the broadest possible participation.
Note: Any OASIS member is free to join a WS-I Technical Committee; you do not have to be employed by a WS-I Member Section Supporting Entity to do so.
Cost of membership
OASIS offers a wide range of membership options and dues designed to ensure that all those affected by open standards have a voice in their creation. There is no additional fee for OASIS members to participate in WS-I.
