Exporting h5 file

FETPAPI
1

Hi Philippe,

Does fetpapi + fesapi package support exporting both .epc and .h5 files by reading the resources and array data from ETP server? I have seen examples where we could use repo.addOrReplaceGsoapProxy to read the data objects from ETP into the repo object, and this repo can later be serialized into an epc file. However it doesnt read the array data and export h5 file. Is there a method that allow us to do this?

Hi Jing,

Indeed, it is easy to write an epc file from an ETP dataspace using FESTAPI but not to write the H5 file.
Rigorously FESTAPI supports it (FETPAPI can definitely reads DataArray and FESAPI can definitely write H5 files with some numerical arrays) but it is not straightforward. No high level methods are provided yet.
Today no one from the FESAPI (paying) customers ask for such use case. Consequently, I do not personally take time to do such development but the community is encouraged to do it if helpful.

Again it is not straightforward :slight_smile:

  • one should go directly at the level of the DataArray handlers to explain to FETPAPI what to do when downloading a DataArray. Porbably deriving this class.
  • then one should write the H5 files with the content of the data array using an the HDF Proxy class

Definitely not easy for a non FESTAPI developer and definitely not the best issue to start with to become a FESTAPI developer. However, I am often surprised in a good way by the skills of member of this community.
