ISSUE-10: Best phrasing for CRS requirements

CRS requirements

Best phrasing for CRS requirements

State:
CLOSED
Product:
Use Cases and Requirements
Raised by:

Description:
This issue was previously raised on the e-mail list: https://lists.w3.org/Archives/Public/public-sdw-wg/2015Apr/0096.html

Currently, there is the CRS Definition requirement (http://w3c.github.io/sdw/UseCases/SDWUseCasesAndRequirements.html#CRSDefinition): "The URI of the Coordinate Reference System (CRS) shall be specified when geographic coordinates are present in the data. To be considered as sub-requirement of 5.30 Spatial metadata" (let's call it req. A)

A Best Practices requirement in the spreadsheet that has not been copied to the UCR document is: "There should be a standard for publishing data about coordinate reference systems (CRS) - Not only geographical reference systems." (let's call this req. B)

Is it OK to regard req A as fully covered by the Spatial metadata requirement?

Can we change the text of the CRS definition requirement (req. A) to the text of req. B?

Proposal:

Replace current CRS requirement to:

"There should be a standard for publishing data about coordinate reference systems (CRS). It should be applicable to any 2D or 3D CRS, not only geographical reference systems. CRS descriptions should be referencable by HTTP URIs."

Also add a separate requirement for having a default CRS.

Frans Knibbe, 27 May 2015, 12:49:36

The requirement for a default CRS has been added to the UCR document: http://w3c.github.io/sdw/UseCases/SDWUseCasesAndRequirements.html#DefaultCRS

We will attempt to make in decision in the meeting of 2015-07-01.

A proposal for rephrasing of the CRS Definition requirement:
"There should be a recommended way of referencing a CRS with a HTTP URI, and to get useful information about the CRS when that URI is dereferenced."

Furthermore, ISSUE-29 (https://www.w3.org/2015/spatial/track/issues/29) has been raised to cover the need for linking a CRS definition to a vector geometry.

Frans Knibbe, 30 Jun 2015, 09:32:18

Accepted proposal in meeting of 2015-07-01: change CRS Definition requirement to "There should be a way of referencing a CRS with a HTTP URI, and to get useful information about the CRS when that URI is dereferenced."
