Web Processing Service 2.0 SWG

 

Purpose of this Standards Working Group

The purpose of this Standards Working Group (SWG) is to evaluate and work the proposed change requests assigned to the Web Processing Service 1.0.0. It will achieve this objective by evaluating and processing the Change Requests listed in Section 3 and ensuring that the standard is consistent with the OGC Processes, OGC standards baseline and the OGC business plan.

Scope of Work

This SWG is focused on processing change requests to be included in Web Processing Service 2.0. The Scope of Work (SOW) will be to collect all outstanding Change Requests, evaluate each of these proposals, and make edits to the standard based on Change Requests and related decisions of the SWG membership.

The work of the SWG will be to consider at least the following Change Requests:

  • CR087 - Include a Cancel request
  • CR088 - Extend version number negotiation
  • CR089 - Make all elementFormDefault = qualified
  • CR090 - Format should include a human readable description
  • CR091 - Correct references to Format
  • CR092 - Implement Corrigendum #1 (08-091)
  • CR093 - Avoiding timeouts
  • CR095 - Application profiles
  • CR096 - Better support for asynchronous services via SOAPN
  • CR097 - Use of ";" in HTTP GET
  • CR098 - Add ability to determine processing capacity
  • CR099 - Add ability to reserve a server
  • CR100 - Simplify HTTP Get Execute encoding
  • CR101 - Align with OWS Common 1.2
  • CR102 - RESTful WPS
  • CR08-037 - Merge SPS and WPS (08-037)
  • CR09-093 - WPS Change Request - Controlling Asynchronous Process
  • CR09-094 - WPS Change Request - "GetStatus" Method
  • CR09-100 - Divide into Core and Extension
  • CR09-101 - Support for SensorML
  • CR09-103 - Format should include a human readable description
  • CR09-107 - Simplify KVP Encoding
  • CR09-109 - methods for controlling, and checking the status of asynchronous process
  • CR09-120 - Extension of the InputReference data structure

Additional Change Requests may be addressed at the discretion of the SWG based on criticality of the change and available time and resources. The closing date for accepting Change Requests is December 6th 2009.

What is out of scope?

Only those change requests addressing the WPS Specification [OGC 05-007r7] and WPS 1.0.0 Corrigendum 1 [OGC 08-091r6] submitted through the formal process as identified in the OGC TC Policy and Procedures will be addressed. Therefore, any items suggested through emails, vocal discussions, etc will be outside of the scope of this SWG until formally submitted.

Specific Contribution of Existing Work as a Starting Point

The starting point for the work will be version 1.0.0 of the Web Processing Service standard (OGC 05-007r7) and WPS 1.0.0 Corrigendum 1 [OGC 08-091r6].

How it is to be Determined when the Work of the SWG has been Completed?

The following criteria will be used to determine the completion of the SWG:

  1. All Change Requests submitted prior to December 06, 2009 have been reviewed and evaluated to the satisfaction of the SWG. This may include working the proposal, rejecting the proposal, or postponing the proposal to a later version.

  2. A completed revision of Web Processing Service 2.0 Standards Documents have been produced and reviewed by the SWG and has been approved for submission to the TC for approval as an adopted standard.

Description of deliverables

The following deliverables will result from the work of this SWG:

  1. A final version of the Web Processing Service 2.0 Standards Documents for submission to the TC.

  2. Corresponding schemas associated with version 2.0 of the Web Processing Service Standards document(s).

The following schedule of activities is anticipated:

  1. Begin the organization and assignment of work activities during the Web Processing Service 2.0 SWG kickoff meeting to be held during TC meetings June 2009.

  2. Review of version 2.0 of the Web Processing Standards document(s) during the TC meetings in September 2013 and in December 2013.

  3. Present draft version of the Web Processing Service 2.0 Standards document(s) at the TC meetings in March 2014.

  4. Standards document(s) submitted to the TC until summer 2014 (northern hemisphere).

The above schedule is meant to serve as a guideline to the SWG in order to determine completion milestones. However, based on the remaining Change Requests, the completion date may adjust in order to accommodate a critical update to the document(s). Although all change requests will be addressed, some may be postponed due to the need to more quickly produce document(s) containing higher priority requests.
