Web Coverage Service 2.0 Revision
Web Coverage Service 2.0 SWG
Work program started: March 19, 2009
Estimated completion date: Early 2010
The purpose of this Standards Working Group is to finish the Web Coverage Service (WCS) Version 2.0 Standard. The SWG will achieve this objective by evaluating and processing the Change Requests listed below, ensuring that the standard is consistent with the OGC baseline and business plan. The charter for this SWG is here.
The WCS 2.0 standard will consist of several documents: a coverage model core, a service core, and several extensions for various purposes. For a minimal WCS 2.0 specification that can be implemented, we will need at least to at least specify the coverage model, service model, and one format extension.
The WCS SWG members agree on the following interim deliverables:
- The WCS netCDF format extension will be presented as discussion paper at the Darmstadt TC meeting in September 2009, with intent to vote on this document to release it as an OGC Discussion Paper.
- The WCScoverage model will be presented as discussion paper at the Darmstadt TC meeting in September 2009, with intent to vote on this document to release it as an OGC Discussion Paper.
- A discussion paper on the service model, ready for discussion & voting, is planned to be available for the Dec TC meeting in Mountain View.
By the end December 2009 a ready-for-voting set of WCS documents is planned to be available. Of course, this is an estimate which is understood to be taken cum grano salis.
