- Registry notes
- Probed 2026-07-26: no feed autodiscovered in the index HTML — but NIST's own feed documentation page (nist.gov/pao/nist-rss-feeds) lists news-events/news/rss.xml plus ~24 topic feeds and 4 blogs; autodiscovery alone under-finds. Re-probed 2026-07-28 at the documented URL: verified end-to-end — 40 items, short teaser descriptions (~134 chars), sample article page extracted cleanly. Content evaluation: article fetch is the substance (descriptions are teasers); ~24 topic feeds remain unregistered depth. Activated 2026-07-28.
How we ingest it
- Channel
- RSS feed
- Method
- Polls the documented news RSS feed via AgencyClient.
- Poll cadence
- about every 60 minutes while the collector runs
- Request budget
- the agency class: at most 1,500 requests per day shared across every agency web source, counted from the fetch log (failed requests count too)
- Politeness
- robots.txt is honored as observed — including each host's crawl-delay, exactly — and every request identifies itself as fapd/0.1 (Free Agentic Publication Digester; +https://fapd.info/bot.html; contact: hustleyourcity@gmail.com); a refusal is recorded, never evaded
- Capture and hash
- captured raw content is hashed (SHA-256) into the day's committed provenance manifest, hash-chained day to day (PROVENANCE.md)
Ingestion health
Ingestion health: delivering 40 item(s) in the last 14 days; most recent 2026-07-28; 5 of 233 request(s) to www.nist.gov returned no content.
This label has held since 2026-08-03T18:46:01Z (UTC) and was last re-checked 2026-08-03T19:51:47Z (UTC).
Counts are of our own requests, retries included. A 4xx or 5xx is the server declining to return content — that may be load, maintenance, on-demand generation, or a limit the publisher sets, and we cannot tell which from outside. Nothing here is a measurement of the publisher.
Ingestion statistics
These figures describe this project's ingestion of this source — items we recorded and requests we made — and nothing else. They are not a measurement of the publisher.
