Originally organized by Databricks Community Meetup Chicago. Speakers Thoughtworks: Eric Nagler and Arun Srinivasan Databricks: [Kevin Hartman](mailto:kevin.hartman@databricks.com) Location 200 E Randolph St. Chicago Floor 25 Hosts Thoughtworks Agenda: 5:00-5:30p.m Happy Hour 5:30 (45–60 min) — AI-Ready Semantic Layers: from ontology to Genie \- The problem: metric views give agents dimensions & formulas\, not part\-of / is\-a / rolls\-up\-to — and Genie Ontology only infers what your assets already encode \(the "right answer\, wrong rollup" failure — not a model problem\)\. \- The moat: the platform moved the floor; the domain\-specific semantic layer \(metric views\, glossaries\, ontology\) is still the differentiator\. \- The build: rapid discovery with the Ontology Accelerator → where to model non\-metric concepts \(tables vs\. UC semantics vs\. ontology vs\. agent\) → two live demos \(infer vs\. supply; end\-to\-end Genie Agent\)\. 6:30 (\~60 min) — Consort (open source) \- What it is: keeps AI\-written code clean and correct — a deterministic state machine drives /plan → /design → /build → /deploy so agents can't skip steps\, weaken tests\, or drift from spec\. \- Why Lakebase: every git branch auto\-pairs with a copy\-on\-write Postgres branch in \~1s — tests run against real data\, not mocks\, and schema evolves in lockstep with code\. \- How it works: 8 role agents \(Spec Author\, Architect\, DBA\, Test Strategist\, UX\, Navigator\, Driver\, Product Owner\) communicate only through immutable artifacts; RED → GREEN → refactor; human\-approval gates that fail closed\. \- The differentiator: engineering discipline enforced by contract\, not suggestions — "green" means a real test pass on live infra\. Live /consort:start scaffolds repo \+ paired DB \+ agents \(StockFlow sample\)\. Venue: 200 E Randolph St, 200 E Randolph St, Chicago, IL 60601, USA, Chicago, IL, United States.
