1. OGC KML 2.3 SWG

2. Purpose of this Standards Working Group

The purpose of this SWG is to develop a first minor revision (V2.3) to the OGC® KML 2.2 Implementation Standard (OGC 07-147r2) to accomodate known issues and extensions identified in formal OGC Change Request Proposals (CRPs) and tested through implementation experience. The SWG will also make corresponding revisions to the companion OGC® KML 2.2 Abstract Test Suite Implementaiton Standard (07-134r2).

The SWG will achieve this objective by evaluating and resolving the submitted KML Change Request Proposals (CRPs) following the criteria in the KML Development Best Practices (OGC 08-125r1).

The SWG will ensure that all changes are consistent with the OGC standards baseline and business plan.

3. Scope of Work

The SWG will be focused on processing CRPs to the OGC® KML 2.2 ImplementationStandard as there are formal outstanding CRPs to this existing OGC standard.

The Scope of Work (SOW) will be to collect all outstanding CRPs, to evaluate and respond to each of the proposals, and if applicable, to make edits to the standard based on CRPs and related decisions of the SWG membership. The SWG, at their discretion, may also ask the membership for any additional change requests that have not been previously submitted. Each of the outstanding CRPs will be evaluated by the SWG according to the criteria identified in the KML Development Best Practices document (OGC 08-125r1). The SWG will then resopond to each CRP, which may include adopting the proposal with or without modification, rejecting the proposal, or postponing the proposal to a later version.

The SWG will address the existing CRPs in the V2.3 revision in accordance with the OGC TC Policy and Procedures. Additional CRPs submitted after the official formation of the SWG may be addressed at the discretion of the SWG based on criticality of the change and available time and resources.

3.1 What is Out of Scope?

This SWG will be focused only on outstanding CRPs submitted through the formal process as identified in the OGC TC Policy and Procedures. Any items suggested through emails, vocal discussions, etc., will be outside the scope of this SWG until formally submitted. CRPs that out of scope, if any, will be determined at the discretion of the SWG membership.

3.2 Specific Contribution of Existing Work as a Starting Point

The starting point for this work will be the evaluation of the outstanding CRPs directed at the existing OGC® KML 2.2 Standard.

3.3 Determination of SWG Completion

The KML 2.3 SWG will dissolve when: 

  1. All CRPs submitted up until the official SWG formation date have been reviewed and evaluated to the satisfaction of the SWG. This may include adopting the proposal, rejecting the proposal or postponing the proposal to a later version.
  2. Recommendations to submit documentation to the TC as a revised standard as approved by the SWG membership
  3. The  revised standard has been approved by the OGC Technical and Planning Committees as an Adopted OGC Standard.

4. Description of Deliverables

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

  1. A candidates for version 2.3 of the OGC® KML Standard for submission to the OGC TC.
  2. Corresponding schema documents associated with the revision for publication in the OGC schema repository.
  3. An annotated list of all CRPs including the comment, submitter, comment type/priority, the response of the SWG, and supporting rationale.
  4. Release notes documenting the changes introduced in the revision.

5. IPR Policy for this SWG

RAND-Royalty Free.

6. Anticipated Participants

The target audience of KML v2.3 includes search engine developers, GIS vendors, mass market software vendors interested in geographic based applications, and consumers.

Details of the First Meeting

The first meeting of the SWG will be held at the OGC TC Meeting in Brussels, the proposed time and date is Tuesday, November 29th at 1:00 PM local time in Brussels.

Projected On-going Meeting Schedule

The work of the SWG will be carried out primarily by email and conference calls, with face-to-face meetings in principle at each of the OGC TC meetings as defined by the chair. Other face-to-face meetings may be called if this can expedite the work of the SWG.
