hey all, another perspective that I have been thinking about is if semantic layers are like ORM for but BI dashboards. Actually, they I think its more than BI dashboards since a similar idea applies to Features. Features in ML land are nothing but a Measure + Entity metadata + TTL. So, really its about higher-order semantics and as we move up the stack, we need richer expression to describe our world.

Feature stores explored here: https://www.xorq.dev/blog/featurestore-to-featurehouse

I think my key takeaway building this is that we need better expression systems and Ibis is a great foundation to build yours..maybe you want to build a language for some other domain etc.

I’m familiar with Xorq. One of features of the Xorq library that I find interesting is that it catalogs data processing (compute) expressions as it compiles, along with call lineage. Makes reuse easier for SQL and non-SQL processing.
