15-day Public Review for OASIS WS-Calendar Version 1.0

The OASIS Web Services Calendar (WS-Calendar) TC [1] members have produced an updated Committee Specification Draft (CSD) and submitted this specification for 15-day public review:

WS-Calendar Version 1.0
Committee Specification Draft 04 / Public Review Draft 03
17 June 2011

Specification Overview:
The WS-Calendar specification adapts the existing specifications for calendaring and applies 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 WS-Calendar specification also defines a conforming model for inheritance to reduce duplication of expression when similar services are requested in a recurring schedule.

TC Description:
The OASIS Web Services Calendar (WS-Calendar) Technical Committee was chartered to adapt the existing specifications for calendaring and apply them to develop a standard for how schedule and event information is passed between and within services. The standard should adopt the semantics and vocabulary of iCalendar for application to the completion of web service contracts.

Public Review Period:
The 15-day public review starts tomorrow, 29 June 2011 and ends 14 July 2011. The specification was previously submitted for a 15-day public review on 09 April 2011 [2]. This 15-day review is limited in scope to changes made from the previous review. Note that since the last review, numerous minor edits have applied across the document, and numerous things that were unclear have been made clearer. Of more substance, the REST and SOAP communications services were removed from the specification as they were not ready at this time. The TC work plan is to bring them back in as part of a later version of the specification

This is an open invitation to comment. OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work.
