Common Data Format (CDF) is one of the scientific data formats
supported in openDX. The current CDF library used in openDX is very
old, and it doesn't support many features (e.g. zVariable) that are
available in the latest CDF library. I'm totally new to openDX (and
have never used openDX before) and trying to assess what it would
take to support the latest CDF features in openDX. I'm just trying
to come up with rough estimate for now and guessing what I have to
do is the following:
1) identify the section of the code that reads and imports CDF data
src/exec/dxmods/import_cdf.c
2) replace this section of code with the new code that can handle
the new CDF data format/structure
3) link openDX with the new CDF library
Am I on the right track or way off? Any comments or help would be
greatly appreciated. I have a feeling that I first need to read the
Programmer's Reference manual before other documents, correct?
This is what its going to take--however, you are going to have to
understand the data model within DX and cdf to understand how to
perform the mapping between the two different structures.
If you need help understanding the OpenDX model--our book will help
and we will try and answer any questions you may have.
BTW, can openDX export data into one of the supported data formats
(e.g. CDF, netCDF, HDF, etc.)? Thanks in advance.
No, but if you build an Importer, it may give you the knowledge to
write an export routine.
