Thanks for contributing these requirements, Linda.

My comments inline.

Could you please elaborate on this? My guess is that the requirement
is about data granularity and/or the ability to easily and efficiently
access slices of huge datasets, but I'm not sure I'm correctly
catching the point.

Can you give an example? I'm overall in favour to this proposal, but
the point is that managing geospatial data require people with
expertise in the domain, and specific tools. Are you talking about
spatial data in general, or "Web-enabled" spatial data?

I think we should be very cautious if we do that. The risk is to
promote (demote) some industry solutions instead of others.

An option would be to list the requirements software should satisfy to
be compliant with the BPs. We may also have a matrix (requirements x
software), to show which requirements are satisfied by existing
software. But also in this case we should be careful about the
implicit message we may be giving.

Do you mean that we need new standards, or rather that we have to
recommend existing solutions? Personally, I would be in favour of the
