[regrep] A spatial search facility - simple demo

[Richard Martell <rmartell@galdosinc.com>]

Hi all,


I posted a proposal for incorporating a spatial search facility:
<http://www.oasis-open.org/apps/org/workgroup/regrep/download.php/9039/regrep-spatial.pdf>

Over the last 18 months or so we have been prototyping such extensions
within a series of OGC test beds, developing a catalogue service
specification based on ebRIM 2.x (but employing a different set of
HTTP bindings).

Here's a link to a simple discovery client that demonstrates
the basic functionality.

<http://indicio.demo.galdosinc.com/ngsc-discovery/discover?service=page/SimpleSearch>

An index map can be used to define a bounding box that is then used to
construct a "window" query (note that this catalogue currently only
associates geometries with dataset descriptions).

This is a prototype, so don't bother with the bug reports ;-)
Other comments or questions are invited, though.
