A Zarr Version of DAP

[DennisHeimbigner]

All-
While it is on my mind, I have been thinking about a DAP equivalent that uses Zarr as the data model. Hope you are familiar, at least in passing, with Zarr.

Anyway, Zarr would provide data model much simpler than DAP4. No sequences, for example. This would make server and client implementations much easier to build, and might lower the adoptions costs for users. I think we could build a standard quite quicky by just reusing much of the DAP4 documentation but using JSON (the Zarr metadata format) instead of XML. We could draw heavily from the Zarr Version 3 specification.

Do any of you have an opinion on the usability/market for this? Would there be some possible source for money to support the development of this: NOAA for example. Of course the money issue is irrelevant to me since I am retired. But it matters to OPeNDAP and Unidata.

Anyway, an idea to kick around.
