[Geomoose-users] GeoMOOSE searching GeoNetwork metadata

[Kevin Grootendorst]

Thanks for this feedback Jim.
Would the current GeoMoose version 2.9.2 support this endeavor or have
features/functions been deprecated since then?
With respect to your second point, my client's GeoNetwork would not be
harvesting data from other catalogs, only an internal database.  I foresee
less complexity in terms of needing mapfiles generated on-the-fly to deal
with projection issues.
In hindsight though, do you think that the GeoMoose - GeoNetwork connection
was worth your time and effort?  Or do you believe that it makes more sense
just to keep the two applications separate?  Given the time and effort
involved, I'm torn between the viability and feasibility of this, versus
some sort of alternate solution.
Cheers,
Kevin
