"description":"Single-frame JPEG (h786poj.jpg, 590 KB, 2592×1944 px, sRGB) extracted from a French motorway speed-camera sequence. Depicts a red Peugeot 308 SW at an oblique 40° rear angle; licence plate FR-AA-000 fully unoccluded and in focus. Reference artefact for ALPR regression tests: standard 23° skew, 98 lx simulated ambient light, 35 km/h forward motion (motion-blur coefficient 0.18). Used as the canonical static input in the alpr and image-meta-extractor workflows to ensure reproducible plate-extraction benchmarks across peers. Served statically from the openalpr.com CDN evaluation dataset; SHA-1 checksum stable across CDN edge pops. Licence: OpenALPR evaluation — non-commercial use only.",
"description":"Rolling series of JPEG snapshots (eu-001.jpg, avg 250 KB per frame, 1920×1080 px) captured at 0.2 Hz (one frame per 5 s) by a Hikvision DS-2CD2T43G2-2I bullet camera mounted 6 m above a Toulouse ring-road on-ramp. H.264-encoded video stream demuxed by an onboard RTSP gateway; individual frames exposed as a static http endpoint refreshed server-side every 5 seconds. Resolution sufficient for single-plate detection at vehicle distance 4–12 m with a 50 mm equivalent focal length. Frames are baseline JPEG (quality factor 85, no progressive encoding) and carry EXIF GPS tag matching the camera pole coordinates (43.6047°N, 1.4442°E). Classified as non-public operational data; OpenCloud federation partnerships restricted to default namespace. Source endpoint served from the openalpr CDN staging mirror; not archived.",

"description":"GRIB2-encoded short-range numerical weather prediction output from the Météo-France AROME-France 1.3 km model over metropolitan France (domain 37.5°N–55°N, 12°W–16°E). Issued 4× daily (00, 06, 12, 18 UTC runs); forecast horizon H+0 to H+48 at 1-hour steps. Fields per level: 2 m temperature (K), 10 m U/V wind components (m/s), total cloud cover fraction (0–1), convective available potential energy (J/kg), cumulative precipitation (kg/m²), surface pressure (Pa), relative humidity (%). Each full-run bundle: ~590 MB compressed (gzip level 6). Served from the Météo-France Données Publiques http API (token-free, rate-limit 500 req/day/IP). SHA-256 checksum file published alongside each bundle. Licence: Étalab Open Licence 2.0 — reuse and redistribution permitted with attribution.",
"description":"Structured NDJSON (newline-delimited JSON) HTTP access-log stream produced by the OpenCloud peer-2 API gateway (Nginx 1.25). Each record: {\"ts\":\"ISO-8601\",\"method\":\"HTTP verb\",\"path\":\"/endpoint\",\"status\":NNN,\"latency_ms\":N,\"peer\":\"opencloud-demo-2\",\"bytes_out\":N,\"upstream_ms\":N}. Rolling 24-h window; approximately 1.2 GB uncompressed per day at typical 300 req/min sustained load with bursts to 2 000 req/min. Flushed to the peer-2 MinIO bucket under /logs/api.log with a 1-minute write interval and gzip-compressed daily rotations retained for 30 days. Consumed by the api-monitoring-stack workflow: CURL fetches the current active chunk, Redis caches per-endpoint status-code distributions and p50/p95 latency percentiles under a 300-second TTL, Nginx serves the aggregated dashboard over HTTP/1.1. Data classification: internal peer-2 operational telemetry; partnerships restricted to default namespace.",
