The OASIS WS-I Member Section operated from Feb 2002 until Dec 2017. The Member Section championed Best Practices for web services interoperability by developing a comprehensive set of Web Services Profiles, Sample Applications and Testing Tools. Three of the Profiles became ISO Standards. The Web Services Basic Reliable and Secure Profiles (WS-BRSP) Technical Committee remains active and the archives of this work are publicly accessible.
Information on this website is preserved for legacy purposes only.

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.

  • If your employer is already a WS-I Supporter...
    You may personally participate in WS-I as a "Member" by notifying OASIS Member Services. As a participant in WS-I, you will receive email notifications of WS-I activities and become eligible to serve on the OASIS WS-I Steering Committee. You may also join OASIS Committees affiliated with the WS-I Member Section.
  • If your employer is an OASIS member but not already a WS-I Supporter*...
    Ask your Primary Representative to notify OASIS Member Services of your intention to become an WS-I Supporter.
  • If your employer is not currently an OASIS member*...
    The first step is to join OASIS and select "WS-I Member Section" on the Membership Agreement. After your organization joins, you and an unlimited number of your co-workers may participate in WS-I and in any OASIS Technical Committees.

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.
