[Neuroimaging] JSON-LD and DICOM?

[Jasper van den Bosch]

Hi all,
I have to agree with Andrey on the yet another format argument. Also, tools
will have to convert it to other formats anyway, so if you do end up
storing something in the header, as long as you document it, just like you
would other nibabel properties, I'd go for the simplest solution.

I did a little survey among niprov users and it turns out they usually
don't end up using the header to store the metadata, because the "central"
storage can more easily keep track of the relationships between files.
And if the file is overwritten, or moved, the metadata remains.
