There are a few minimum format requirements to enable you systems to communicate with the OceanDataPortal Data Provider software.
Metadata is presented in XML
format based on ISO 19115 standard and WMO Core Profile v.0.1. Now we

Data is presented in NetCDF format. Wikipedia:
The data format is "self-describing". This means that there is a header
which describes the layout of the rest of the file, in particular the
data arrays, as well as arbitrary file metadata in the form of
name/value attributes. The format is platform independent, with issues
such as endianness being addressed in the software libraries. The data
arrays are rectangular, not ragged, and stored in a simple and regular
fashion that allows efficient subsetting.
