We are actively developing a solution to this at Splitgraph [0].

We’re looking for our first customers / design partners for the self-hosted / on-prem product.

I would love to talk to you, but you’ve got no contact in your profile. Can you email me at miles@splitgraph.com and we can set up a time to chat?

Would be curious to better understand your needs in this space. I work at an early stage VC firm and have met probably ever single catalogue/metadata startup - shoot me an email at davis (at) innovationendeavors.com if you want to share notes on the space. I can potentially recommend a few options.
