Changes for Version 0.9 Beta

This list summarizes changes since the release announcement of Version 0.7. Some of these changes were already introduced prior to the release of Version 0.9, as incremental updates to Version 0.7. This list is a summary; that is, it does not specify all changes.

Notes: There was no Version 0.8 (that number was skipped).

Conditions (appendix) - new material

Explains and illustrates an approach to representing conditional expressions (as used in conditional outputs, preconditions, effects, and conditional control constructs).

Security constructs (appendix) - new material

Explains and illustrates an approach to expressing security capabilities and requirements, in service profiles.










Changes for Version 0.7

Version 0.7 introduces the Grounding ontology, and includes some refinements to the Profile and Process Model ontologies. In addition, a new example of a Profile-based (yellow-pages style) service taxonomy is presented, and the existing service examples have been made more complete. The new Grounding ontology ties DAML-S in with the Web Services Description Language (WSDL), an emerging, collaborative industry effort that is currently the focus of a W3C working group.
