[Nexus] Names of linked items

[Osborn, Raymond]

Hi Mark,
Thanks for bringing me up to date. I’ve been living in the past, but the master branch of NeXpy now allows renamed links, so I’m catching up.

Dear Colleagues,

The Dectris HDF5/Nexus files use different names for their data links.

Regards,
  Herbert


For a long time the links had to have the same names as the original object. But by decision of NIAC this was changed
and added to NAPI. See NSmakenamedlink. I remember because I implement it

Best Regards,

Hi everyone,
This is a question for the NeXus old-timers (Mark?). I received a request for NeXpy to allow links to have different names to their parent objects. I had assumed that the standard required that the linked parents and children have the same name, and all the examples in the documentation do, but there doesn’t seem to be a declared rule about it.

There is no problem implementing different names in NeXpy, which only writes HDF5 files, but my recollection was that HDF4 links had to have the same name because of the way objects were attached to Vgroups. Am I wrong about that? If I’m not wrong, does napi5.c care if the names are different?

Thanks,
Ray
