Schedule Signals and Streams Version 1.0 published by WS-Calendar TC

OASIS is pleased to announce the approval and publication of a new Committee Specification by the members of the OASIS Web Services Calendar (WS-Calendar) TC [1]:

Schedule Signals and Streams Version 1.0
Committee Specification 01
18 September 2016

What is Schedule Signals and Streams?

There is a common need to communicate information linked to repetitive intervals of time, for history, for telemetry, for projections, for bids. Much of the information in each interval can be inferred from the surrounding intervals. The document defines a normative structure for conveying time-series of information that is conformant with WS-Calendar. We term these conveyances "Streams".

This is a final deliverable. Completed and approved by the TC, this OASIS Committee Specification is fully ready for implementation. If submitted for further ratification as an OASIS Standard, its content will not change.

About the TC:

The OASIS WS-Calendar TC works to adapt existing calendaring standards (used in human interactions) for Web services. WS-Calendar is designed for use inside other specifications and standards, bringing a common scheduling and performance alignment to service coordination, including between domains.

Coordinating schedules and activities is critical to connecting the processes and activities of the internet of people with the internet of things. The initial work of WS-Calendar is finding use in enterprise scheduling, in energy markets, particularly in the EMIX and Energy Interoperation specifications, and in combination with BIM (Building Information Models) to enhance energy models.

Other specifications of the WS-Calendar TC include WS-Calendar, SOAP-based Services, REST-Based Services, and a Platform Independent Model (PIM) for Calendar and Schedules.

Members of the WS-Calendar TC approved this specification by Special Majority Vote. The specification had been released for public review as required by the TC Process [2]. The vote to approve as a Committee Specification passed [3], and the document is now available online in the OASIS Library as referenced above.

Our congratulations to the TC on achieving this milestone and our thanks to the reviewers who provided feedback on the specification drafts to help improve the quality of the work.
