[Nexus] HDF5 as NeXus file format

[Watts Benjamin (PSI)]

Hi Gabriel,

   NeXus is officially not dependent on HDF5 and we are definitely open minded about implementing the NeXus data format on file formats other than HDF5. We plan to discuss such issues at our next teleconference<https://www.nexusformat.org/Telco_20220426.html> on April 26th and I invite you to join us. Are there specific container file formats that you are interested in?


Cheers,

Ben

Subject: [Nexus] HDF5 as NeXus file format

Dear NeXus Users Community,

Last NFDI NeXus Workshop was a great opportunity to meet the community and learn from the experience of other scientists and institutions.

Here at ALBA we are working on the integration of NeXus files in our data analysis workflows.

In this scope we are interested on investigating alternatives to hdf5 as NeXus file format, in terms of slice read/write performance, read-write-many capabilities and convenient reading.

Would the community be open to decoupling the data format (NeXus) from the file format (HDF5)?
Is there already any effort in the community in this direction?
Is anyone else also interested?


Best regards,

Gabriel
