Great, thanks for the offer :smile: I think I'll start with a minimal repo back at ArviZ and see how much of that can be used more generally. I probably should have named the example above arviz_dot instead. I definitely want to be able to do arviz_dot(a, b) and have it work automatically because in most ArviZ cases we do have all the information we need for this to be possible. We'll therefore definitely need a higher ArviZ layer, but I think an xarray-linalg would be a great base on which to build and we can keep both in different files/modules so it can be split easily.

I also commented here as I thought it was the most related issue, many of the functions I have in mind are related to linalg, but we'll probably have some other functions too.
