Original URL, capture timestamp, and content hash travel with every record — even if the upstream page goes 404.
Reported incidents involving the space for civic action — restrictions, arrests, shutdowns, dispersals, press-freedom events. Surfaced from the open record by an AI agent swarm, deduplicated across sources, and published at Silver tier with full provenance.
A daily-refreshed dataset of reported incidents involving the space for civic action: legal restrictions on assembly, arrests of activists and journalists, internet shutdowns, protest dispersals, NGO de-registrations, and press-freedom events. Global coverage; the schema is the same wherever the incident occurred.
An AI agent swarm reads the open record around the clock, extracts each candidate claim against a fixed schema, and only publishes an event once the Silver gate is satisfied — at least three independent sources and a corroboration confidence above 0.7. Bronze-only signals are kept internally for review but never reach the catalog.
Every Silver record carries the chain-of-custody attributes the Berkeley Protocol on Digital Open Source Investigations expects: original source URLs, capture timestamps, content hashes, the raw extraction payload, and full edit history. Djeed delivers Silver — the verification + ethical-review steps that turn it into admissible Gold happen inside your workflow.
“Authorities ordered the shutdown of two independent newspapers and arrested three reporters covering the protests.”

The full per-record property set unlocks with a subscription. Free-tier callers get the main fields shown above plus the geometry needed for the map and graph views.
The Silver gate requires corroboration across independent source categories — multiple outlets in one category don't alone clear the bar.
A new claim arrives at Bronze the moment the swarm extracts it from a single source. It stays at Bronze until at least two more independent sources back it within the spatial-temporal corroboration window (same event, same place, within a few days). When the cluster's combined confidence crosses 0.7, the claims are merged into one Silver event — entity names are reconciled, locations are reverse-geocoded to administrative units, and an H3 hex cell is assigned so the event can be spatially blocked against future arrivals.
Four criteria the Protocol expects, four ways this dataset satisfies them. Full mapping of all ten criteria is on the methodology page.
Berkeley criterion
Original URL, capture timestamp, and content hash travel with every record — even if the upstream page goes 404.
Berkeley criterion
Silver gate: ≥ 3 independent sources AND corroboration confidence ≥ 0.7. Single-source claims never reach the catalog.
Berkeley criterion
Every value change, dedup merge, and tier promotion is logged; the full edit history is queryable.
Berkeley criterion
Raw extraction payload preserved per record so a disputed value can be re-checked against the original page.
Free-tier sees a curated subset of these fields in the inspector panel. The full schema (every field above, plus the raw extraction payload) is subscription-only.
