Why talk about Why talk about standards?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”

Standards affect the Standards affect the cost of e-commercecost 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

Coordination of Coordination of standards at OASISstandards 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.

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?
