I like the idea of a semantic Layer but don't think defining it in yaml is the right way to go about it.

Semantic Layer needs proper language and tooling support which Malloy provides.





Yeah, we still have them, MDX before and now DAX :)

I curate some more on here in case of interest: https://www.ssp.sh/brain/data-modeling-languages.


MDX really did it well, at the cost of being impenetrable to the average user - the drilldown flow you could get is still hard to beat.

Shameless plug for the list, though - I work on https://github.com/trilogy-data/pytrilogy - semantic layer directly embedded in otherwise (mostly) SQL syntax.

I'll do an equivalent example on the taxi dataset when I have some time.



Anything but a markup language / JSON.

are you using Malloy in prod? Do you know of anyone? I remember the Malloy hype during Data Council in 2023. Haven't heard about it since.

Not yet, but it's evolving nicely, the original team moved to meta and they are building interesting open source stuff

i think the team moved on from google ( which was the main benefactor)
