15-day Public Review for Schedule Signals and Streams Version 1.0 from Web Services Calendar (#WS-Calendar) TC

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

Schedule Signals and Streams Version 1.0
Committee Specification Draft 02 / Public Review Draft 02
24 May 2013

Specification Overview:

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".

TC Description:

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.

Public Review Period:

The public review starts 09 July 2013 at 00:00 GMT and ends 24 July 2013 at 23:59 GMT. The specification was previously submitted for public review [2]. This 15-day review is limited in scope to changes made from the previous review. Changes are highlighted in the diff-marked PDF file [3].

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.
