[StarRocks @StarRocksLabs]

🆕 A while back, @open_metadata added the StarRocks connector.

This makes it easier to bring metadata into OpenMetadata, including schemas, tables, column types, and view definitions via StarRocks’ MySQL-compatible interface.

[Roman Medvedev @roomavm]

I audited unofficial Openmetadata CLI from romamo/openmetadata-cli against 22 Critical CLI Agent Spec failure modes.

Even though it was built during a hackathon, it has the best score among all the other tested tools.

Result: 1.5/3 average. Readiness: 12/15 [B].

This CLI already has a serious agent-first foundation: JSON envelopes on normal commands, schema introspection, dry-run mutation previews, MCP mode, bundled agent skills, non-TTY SSO protection, and prompt-injection tagging for external data.

The remaining gaps are mostly contract gaps, not conceptual gaps.

The two failing Critical checks were:

§43 output size: no max-output flag, truncation metadata, or schema-declared output cap.

§74 credential scopes: schema does not declare required_scopes and there is no check-permissions preflight.

The partial failures matter too: timeout maps to GENERAL_ERROR, credential expiry maps to AUTH_REQUIRED, invocation errors can bypass JSON, and dry-run output lacks affected scope/effect fields.

Bottom line: omd is close to being highly agent-ready. The next step is making every failure and credential boundary machine-readable.

Data30 - Session 6 is live in 1 hour!

From Metadata to Meaning: RDF & Ontologies

Today, Wed May 20 | 9:00–9:30 AM PT

The challenge for AI isn't access to data anymore, it's understanding it. Today, we're showing how @CollateData turns metadata into a semantic knowledge graph that AI agents can reason over with accuracy and context.

"Data catalog" became a bad word at @Scout24 after their legacy catalog failed.

After modernizing with @CollateData, Head of Data Infrastructure and Governance, Angelita Frozza Sanches implemented their "context catalog"

The goal: give AI agents and people shared meaning, ownership, and trust signals for every data interaction.

She presents the full build at Collate Summit, June 10.

@Scout24 runs @Collatedata, built on @open_metadata, in production and calls it a "context catalog."

AWS, Starburst, Collate. MCPs for GitHub + Confluence. AI-generated docs, human-certified. PII tags propagate from Collate to the query engine for agent-level governance.

Before you deploy an AI agent, ask yourself one question:

Does your data have an agreed-upon meaning that a machine can actually read?

If the answer is no, the agent will guess. Every time.

Semantic intelligence is the trust layer that fixes this. It turns metadata into machine-readable context that both humans and AI can rely on.

At @CollateData Summit, we're going deep on how to build it.

This Wednesday at 11 AM PDT, our CEO & Co-Founder @suresh_m_s is on stage with @DataSciConnect.

The question on the table: as enterprises push AI into production, how do you ensure outputs reflect the right data, tone, and constraints, every time?

It's a context architecture question. And the answer is becoming foundational to trustworthy AI.

Free. One hour. Worth it.

A data steward opened Ontology Explorer for the first time. Two minutes in, she spotted it:

Three definitions of Revenue (Finance, Sales, Product) with zero formal relationships between them. Every version was being used downstream, feeding different answers into the same questions.

She resolved it on the canvas:

→ Marked Finance as the authoritative definition
→ Declared equivalence to the Sales and Product versions
→ Tagged GDPR governance once at the concept level, which propagated automatically to all 847 implementing assets

That's the difference between maintaining a flat glossary and governing an ontology. 🗺️

OpenMetadata 1.13 Ontology Explorer is your entire business vocabulary as an interactive graph, with term hierarchies, cross-domain connections, and a Data Mode that traces every term to the data that implements it. Ontology Explorer surfaces coverage gaps instantly. If your catalog has 34 glossary terms with zero relationships, opening the graph makes them visible immediately.

Hallucinations aren't a model problem. They're a context problem.

When AI systems don't have access to the right data, the right tone, and the right constraints at the right time... they guess.

Next Wednesday, our Co-Founder & CEO @suresh_m_s is breaking down how leading teams are solving this, with context-aware architecture built for production.

Pick any table in your catalog. Try listing, in under a minute, every team that depends on it, every glossary term it maps to, and everything that breaks if the schema changes. Most people can't. That's why we built the new Knowledge Graph visualization. 🔮

OpenMetadata 1.13 renders the full relationship context of any asset in a single interactive view:

→ Ownership, teams, and domain context
→ Schema hierarchy, upstream sources, and downstream consumers
→ Business semantics, plus relationships inferred automatically from your metadata

Built on open W3C standards (RDF, OWL, DCAT, DPROD, SKOS, PROV-O, https://t.co/05L7nUpZOZ) for portability and interoperability. Every AI agent that queries your data, including those through MCP, reasons from the same semantic context graph of ownership, lineage, and glossaries.

See your entire data ecosystem in one view instead of digging through spreadsheets and Slack threads.

@suresh_m_s just got off the Data Summit stage, where he made the case that AI doesn't fail because of bad models. It fails because the data underneath has no shared meaning.

Tonight?

An evening of exactly that conversation. Metadata, governance, and making AI actually work in production at the @CollateData + @open_metadata Boston meetup.

Good conversations don't stop when the conference ends.
