we need to know what parameters are in the odv: we ask a file. We get the codes and second step we execute.
Cruise Station Type … LOCAL_CDI_ID EDMO_code … COREDIST [meter] QV:SEADATANET

You give some data and metadata, we give back visualization services, via some input and output specifications
How to integrate to seadatanet: ODV caches. We have Matlab lib, python lib, parsing P01, postgres, netcdf,

Plot on the flight with JavaScript
Pop-ups in the browser
Oceanbrowser making the interface
pyWPS can be host in the same server where data is
