How sources are monitored
Port checks its sources on a schedule and treats every change as something to review, not something to publish automatically.
Explanation Marine Deep's explanation, not a requirement.
What the monitor does
Our monitor (user agent MarineDeepPortMonitor) fetches each source page on a schedule, usually weekly, and some change feeds daily. It sends conditional requests so unchanged pages cost the publisher almost nothing, spaces requests to each site, and respects robots.txt. Where a publisher does not allow automated access, we check the source manually instead.
What happens when a source changes
- The change is recorded with the date it was detected.
- Any Port statement whose supporting text is no longer in the source is held back from the site automatically.
- The change is classified. Changes to law or codes, and anything touching diving-safety subjects, go to a human reviewer. Cosmetic changes to guidance pages are accepted automatically; that only updates the "last checked" date.
- Once reviewed, statements are re-verified or rewritten, and an update may be published.
What the dates mean
- Sources last checked: the oldest check among the sources a page relies on.
- Editorial check: when the page's wording was last reviewed.
- Edition / date: the edition or date the publisher gives the source.
If a page shows review due, a source has changed or a check is overdue. Rely on the linked primary source until it clears.
