2. © OASIS 2003 Why talk about standards? A standard is:  publicly available in stable, persistent versions  developed and approved under a published process  open to public input:  public comments, public archives, no NDAs  subject to explicit, disclosed IPR terms Anything else is proprietary:  This is a policy distinction not a pejorative  See the US, EU, WTO governmental & treaty definitions of “standards”

3. © OASIS 2003 Standards affect the cost of e-commerce  Data conversion, process analysis and personnel training can be large expenses when adopting an e-commerce system  These costs can be balanced against tremendous operational savings -- but only if the user can employ the system for a sufficient period of time to enjoy them  Instability can thwart that recovery:  Insufficient breadth, obsolescence, competitive “embrace and extend” changes, IPR restrictions, over- versioning, sudden withdrawal

4. © OASIS 2003 Coordination of standards at OASIS  W3C and OASIS management regularly confer  Many dependencies across standards  Elements from OASIS standards are submitted to other SDOs, e.g.,  IETF, ISO, etc.  OASIS participates in many other standards and industry coordination efforts, e.g.,  ISO/IEC/ITU global coordination MoU  RosettaNet, OMA, etc.  AIAG, WS-I, GGF, etc.

12. © OASIS 2003 Let’s talk  Do you agree with the weather report?  Should users implement web services with proprietary products or wait for the standards?  Is conformance and interoperability part of the lifecycle of a standard?  How can we move from (inside) enterprise services to (B2B) web services?
