Subject: Public Review of WS-Calendar v1.0 and Conceptual Overview of WS-Calendar

To OASIS members, Public Announce Lists:

The OASIS WS-Calendar TC has recently approved the following specification as a Committee Draft and approved them for public review:

WS-Calendar Version 1.0
Conceptual Overview of WS-Calendar CD01 - Understanding inheritance using the semantic elements of web services

The WS-Calendar specification adapts the existing specifications for calendaring and apply them to a new specification for how schedule and event information is passed between and within services. The standard adopts the semantics and vocabulary of iCalendar for application to the completion of web service contracts. WS Calendar builds on work done and ongoing in The Calendaring and Scheduling Consortium (CalConnect), which works to increase interoperation between calendaring systems, and the Internet Engineering Task Force (IETF). 
The specification describes how to specify a sequence of services, how to schedule them, and how to invoke them. The specification was developed to support use cases in smart grids and smart energy, but it supports any sort of coordinated activities between domains. The committee explicitly considered coordination between energy coordination, enterprise systems, building systems, and financial markets. The specification also defines an inheritance approach wherein information common to many time intervals is specified for an entire sequence, while supporting over-rides within any time interval. 

The committee is simultaneously releasing white paper for public review. The white paper provides a conceptual overview of the specification and its use. The committee recommends those encountering WS-Calendar for the first time to read the white paper before reviewing the specification. 

The committee anticipates that the primary use for the specifications is inclusion in other specifications, providing a common mechanism to solve coordination communications. Technical committees currently planning to incorporate WS-Calendar include the OASIS Energy Market Information Exchange TC (EMIX), the OASIS Energy Interoperation TC (EnergyInterop), and the OASIS Open Building Information Exchange TC (oBIX). 

The committee plans to submit the new semantic elements of Interval and Sequence, as well as the new inter-object Temporal Relations to the IETF for inclusion in iCalendar at a later time. 

The public review starts today, 24 September 2010, and ends 23 November 2010. This is an open invitation to comment. We strongly encourage feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of OASIS work. We also welcome interested parties to join the TC as it continues to further development of its specifications. [or more specific info from TC].

We also call your attention to the OASIS IPR Policy applicable to the work of this technical committee, which can be found at [4] below. All members of the TC should be familiar with this document, which may create obligations regarding the disclosure and availability of a member's patent, copyright, trademark and license rights that read on an approved OASIS specification. OASIS invites any persons who know of any such claims to disclose these if they may be essential to the implementation of the above specification, so that notice of them may be posted to the notice page for this TC's work, at [5] below.
