Group Description:




The WFS/FES SWG will, in cooperation with ISO/TC 211 produce revised versions of these standards based on change requests posted to the OGC change request page, the comment log from ISO/TC 211 members during the voting on the revisions of ISO 19142 and ISO 19143, and engineering reports produced during OGC Testbeds.



The WFS/FES standards have been used by many public and private organizations, including OGC Testbeds, since the last revision of these standards. As a result, a sufficient number of change requests have been posted to the OGC change request issue tracker.  Comments from ISO/TC 211 members will also be added to the issue tracker, as one issue with several comments. A number of these CR's deal with corrections or modification that need to be made to the standards resulting from implementation and Testbed experience.  There are however several change requests that propose new and important additions to the WFS/FES specifications based on work performed within and outside the Testbeds.  Most importantly, CR 11-080 proposes the addition of a REST binding to the WFS standard. The newly created SWG will review the CR’s and develop new versions of the WFS and FES standards for joint adoption by OGC and ISO/TC 211.

2     Purpose of the Standards Working Group

The purpose of the OWS WFS/FES SWF is to address the CR's that have been posted to the OGC change request page, comments from ISO/TC 211 members in the ISO voting process, as well as those found in engineering reports produced during OGC Testbeds.

3     Scope of Work

The following constitutes the scope of work for the SWG. The SWG shall perform the following activities:

  1. Access CR's posted to the OGC change request page, comments from ISO/TC 211 members, and and relevant engineering reports developed during the OGC Testbeds and review these inputs in the context of the latest version of the OGC WFS/FES standards (ISO 19142 and ISO 19143).
  2. Revise the standards based on the source material.
  3. Address any other technical and/or editorial issues related to CR’s already submitted that arise during the review period.

3.1      What is out of scope?

Only those functional requirements and comments already submitted through the formal processes in OGC and ISO as identified in the respective Policies and Procedures and directives shall be addressed. Items suggested through emails, vocal discussions, etc. will be outside of the scope of this SWG. 

3.2      Existing Work as a Starting Point

The starting point for the revised implementation standards shall be documents OGC 09-025r1/ISO 19142 and OGC 09-026r1/ISO 19143.

3.3      Source material

Change Requests and comments from the OGC and ISO processes, as identified above, will comprise the primary source material for revision to these standards. 

Engineering Reports from several OGC Testbeds reference these standards and will also serve as sources for revision.

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

The WFS/FES SWG shall be made inactive after the following milestones have been achieved.

  1. The SWG has reviewed the relevant source material and revised the WFS and FES standards.
  2. SWG membership approves a recommendation to submit the documents to the TC for consideration as OGC adopted standards.
  3. The candidate standards have been approved by the OGC Technical and Planning Committees as OGC adopted standards and as revised ISO Standards according to the ISO directives.

4     Description of deliverables

There shall be at least two deliverables:

  1. A revised 2.x version of the WFS standard.
  2. A revised 2.x version of the FES standard.

The preliminary schedule of the SWG is as follows:

  • start date: 1st of November 2011
  • drafting of candidate standards on a mutually-agreeable schedule by OGC and ISO/TC 211
  • periodic public review of candidate standard drafts
  • synchronized approval activities in OGC and ISO per the guidance of the Joint Advisory Group (JAG)

5     IPR Policy for this SWG

The IPR Policy for the WFS/FES SWG will be RAND-Royalty Free.

6     Anticipated Audience

The anticipated audience for the SWG deliverables is any organization that has implemented or is interested in implementing web servers or clients based on the WFS and/or FES standards.

7     Other informative information about the work of this SWG

7.1      Details of the first meeting

The first meeting of the committee will be held by telephone conference call during the week of 01-NOV-2011.  Call-in information will be provided to the SWG's e-mail list and on the portal calendar in advance of the meeting.

7.2      Projected on-going meeting schedule

The work of the committee will be carried out primarily by email and conference calls, possibly every two weeks, with face-to-face meetings perhaps during each of the OGC TC meetings.
