access to ISO standards - was Re: [Geotools-devel] [OSGeo-Standards] [Fwd: ImageIO MetaData]

Dear GeoToolies:

Concerning 

"2>ISO 19123 is not available for free, hence this can be a show
stopper for people(I know it is not expensive but still, many OGC
documents are referring to an ISO specification that you are supposed
to pay for. (Well, IMHO, this is quite strange, what does Open stand
for in the acronym OGC? :-) )."

Many of the ISO standards are identical to volumes of the OGC "Abstract
Specification", so the important ones are in fact available under a
different cover from the OGC site. Does not apply to all, and there is
sometimes a time-lag between ISO standards getting issued by ISO and
them getting re-issued as OGC documents, but this issue is actually not
as bad as it seems.

To summarise, the problems I see:

1>A lot of documents, as I said, refer to ISO 19123 implicitly while,
afaik at least, GridCoverage IS is still THE adopted specification for
GridCoverage, afaik at least.

2>ISO 19123 is not available for free, hence this can be a show
stopper for people(I know it is not expensive but still, many OGC
documents are referring to an ISO specification that you are supposed
to pay for. (Well, IMHO, this is quite strange, what does Open stand
for in the acronym OGC? :-) ).

3>GridCoverage IS was made of mainly 3 parts (as far as I can remember
at least :-) )
   - GridCoverageExchange  that proposes a model for I/O
   - GridCoverageProcessor that proposes a model for GridCoverage
Processing
   - GridCoverage that proposes a model for GridCoverage

Well ISO19123 does NOT propose anything about I/O or processing
itself. There might be other ISO specs, I admit my ignorance about
this, but I also admit that I do not want to get into the Dependency
Graph of ISO specs which could cost me a few thousands Euros :-).
