Validate dummy data

I am trying to put together a dummy ZARR file (ideally as small as possible, i.e. structured but empty) in order to provide a minimal exaple to test .zarr support for the BIDS data validator (more info on that here: https://github.com/bids-standard/bids-examples/pull/315 ).

I have found this website, and tried to upload my example data on my server, to see whether it's valid ZARR: http://resources.chymera.eu/data/sub-01_ses-01_sample-A_SPIM.ome.zarr

But the website returns NetworkError when attempting to fetch resource. for https://ome.github.io/ome-ngff-validator/?source=https://resources.chymera.eu/data/sub-01_ses-01_sample-A_SPIM.ome.zarr

Any idea what I can do, or do you perhaps have some very minimal dummy data examples? There seem to be some examples under ./fixture/ as part of this repository, which I assume are defined as valid, but (1) most of them seem rather larger than necessary for a single minimal example, (2) there exists a ./fixture/.zattrs file — does this mean that fixture is just one example?

As @satra mentioned in https://github.com/bids-standard/bids-examples/pull/315#issuecomment-1184871664, your Zarr fileset is missing the metadata files that are necessary to decipher the data. Can you share how you created it and how you uploaded it?

You can find sample data under https://idr.github.io/ome-ngff-samples/, but not dummy data. The data files can all simply be deleted though. (Missing data chunks use the fill value). Some smaller test data is available here: https://ome.github.io/ome-ngff-validator/?source=https://raw.githubusercontent.com/ome/ome_zarr_test_suite/de08d3fda787a100b3828c4d5c2da4968facb800/data/64x64-fake-v0.4/0

Closing in favor of #1246 under the umbrella of "where should test data live?" But if there are any other questions, please let us know.
