[ckan-dev] GIS dataset import

Fri Jan 17 19:42:47 UTC 2014

Hello Adria,

great to hear that.
I agree that splitting visualization and harvesting would help maintaining
the code tree.
FYI, i'm also working on an improved CSW harvester, to better extract
online resources and recognize OGC endpoints. Is there any ongoing work in
that respect?

As for the dashboard feature, this sounds inline with a project i'm working
on to exchange aggregations of data chunks. Looking forward to how this can
be integrated.

thank you,

--p.
