Overview

With the introduction of .nde version 4.0, there are modifications to the HDF structure and to the JSON Setup dataset.

You may want to upgrade your application so it is compatible with new .nde files.

Upgrading your application to read/write NDE files from version 3.3 to version 4.0

We recommend the following procedure to upgrade your application reading and/or writing .nde version 3.3 files to be able to read and/or write .nde version 4.0 files:

  • Update the routine in charge of reading/writing the HDF root attributes for the new metadata JSON Properties dataset located under the new /Properties path following the upgrade guide.
  • Update the routine in charge of reading/writing the HDF datasets currently located under /Domain/DataGroups to the new /Public/Groups path following the upgrade guide.
  • Update the routine in charge of reading/writing the JSON Setup dataset currently located under /Domain/Setup to the new /Public/Setup path following the upgrade guide.
  • Update any routine in charge of reading/writing data located under /Applications to the new /Private path.
