[Live-demo] [eoxserver-dev] EOxServer - an Open Source WMS/WCS for Earth Observations & OSGeo-Live

Sat May 26 06:14:15 PDT 2012

Stephan,

I would suggest having a look at pycsw [1], that could be integrated in 
your django application and offer CSW (INSPIRE compliant) service.

Best regards,
Angelos
