Im of the opinion its not the right thing to do, because things > like metadata cant be kept consistent. Hi John, Brian and I are working on implementing an ideal way to get data from a relational database that contains in situ measurements from platforms that produce mostly trajectory feature type data. We've put the data into a GeoSpatial RDBMS so that we can take advantage of the arbitrary column and spatial indexing capabilities. We have a web application that provides previews of the data and can generate urls for service calls (much like erddap). We would like our users to load the data via such a service call directly into tools that use netcdf-java. If there is some way to make the metadata consistent perhaps we can discuss that... Best regards, Mike
