Re: Further work on the Use Cases and Requirements document

Hi all,

in the below document there is the stanza "The WG will develop a formal
Recommendation for expressing discrete coverage data conformant to the ISO 19123
abstract model" in 2.5. As already pointed out at the joint W3C/OGC meeting this
will hinder interoperability: many different implementations of the same
abstract model are possible, and have been done actually.

But there is more: ISO is currently restructuring 19123 into
- 19123-1, the current abstract model
- 19123-2, the coverage implementation model
the latter will be based verbatim on OGC 09-146r2 which establishes OGC's
authoritative coverage model. This will be done through a fast track procedure
(ISO is convinced about the approach, based on both concepts and massive
implementation evidence), so 19123-2 will be ISO standard on very short notice.

Hence, if W3C will not use OGC's adopted coverage model it will own an
implementation model which is not interoperable with OGC, ISO, INSPIRE - in
short: the rest of the world. Therefore, let me suggest to rephrase 2.5
accordingly. At this stage it does not cost much yet (as usual in the software
life cycle).

Just wanted to raise awareness of the issue in this group.

cheers,
Peter
