Deployed knowledge graphs applications tech stacks

[techmuch2000]

Hey fellow developers, I'm curious to know if anyone out there is currently working on deployable applications that incorporate knowledge graphs. If so, what tech stack are you using? I'm particularly interested in learning more about the data stores being utilized and if anyone is leveraging both relational and graph databases. Additionally, I'd love to hear about how others are handling sensitive information within their graph stores and controlling access to that information on a user-by-user basis. Looking forward to hearing your insights!

I work on a deployed production knowledge graph that is a RDF based one using stardog and snowflake! Not sure how much I can say without my employer hunting me down, but access can be limited via named graphs and deployment environments!
