External services for "Open with" for zarrs to browse them: add quiltdata

[yarikoptic]

relates to good old

• Add URL to browse the zarr to the error message #1746

as ATM we do not provide file navigator within zarrs, and to an alternative solution suggested

• Add webdav.dandiarchive.org to "services" for the main instance and redirect /download/ for zarrs to webdav  #1993

but since "bundled" with handling for /download, the web UI aspect was forgotten/never implemented!

I think it is time to implement support for that and also quiltdata which provides a convenient navigator for S3 (demoed by @dyf at sfn 2025). So for a zarr, since it is a key prefix on S3, would work beautifully:

https://open.quiltdata.com/b/dandiarchive/tree/zarr/7b617177-ad57-4f7f-806b-060e18f42d15/ for the one from https://dandiarchive.org/dandiset/001675/draft/files?location=pipeline-aind%2Bephys/blobs/048d1ee9-83b7-491f-8f02-1ca615b1d455/run-1&page=1 .

Note that since it is embargoed, it would/could (needs DANDI API key entered, related fresh filed: flatironinstitute/neurosift#368) work only with neurosift and not webdav (public only ATM).

To add support for that type of URL we would need to parse out zarr_id from the contentUrl entry which points to amazon directly. Unfortunately we seems to not expose content ID here

• Add contentId to asset metadata dandi-schema#356
