[mapserver-users] fetching netcdf from web service

Hi,
I was hoping to expose some ocean data as WMS using mapserver, where the
netcdf data is fetched on demand from the erddap server.
The gdalinfo command appears to show something useful, however the
corresponding ogrinfo command doesn't, and neither have I been able to come
up with a mapfile to see any kind of data fetched from erddap and rendered.
Has anyone done this or can you offer any tips?
Thanks,
Rob.
