How listings are verified

What a listing needs before it goes up

1. A start and end date published by the organiser, on a page the organiser controls. A "save the date" without a day, or a date from a ticketing site or a news article, is not enough.
2. A named venue. A city alone is not a venue; "venue to be announced" means the listing waits.
3. A named organiser. The company, foundation or association that runs the event, as its own page names it, including in the copyright line or the footer when that is where it appears.
4. The organiser's page for that edition, which becomes the "official site" link on the listing.

If any one of these is missing, the event is not listed, however well known it is. The 20 listings on the directory today were built this way from 17 organisers' sites; several well-known conferences are absent because their pages did not state a venue or a full date on the day they were checked.

What is recorded

Every listing carries the source page and the date it was read ("last verified"). The dossier at the top of an event page is the whole of what was verified: dates, venue, city and country, organiser, official site, status, source, verified date. The summary below it restates facts from the same page and may note what the organiser says about a rebrand, a move or a date change; it does not add opinion.

What a listing does not contain

No ticket prices, because they change weekly and the organiser's page is the only place they are right. No attendance figures, because organisers publish projections and this site cannot check them. No speaker lists, for the same reason. No ratings, reviews or "worth attending" verdicts. A listing is the answer to four questions: when, where, who runs it, and where to read more.

Upcoming and past

An edition is "upcoming" until its last day has passed, and only upcoming editions carry event markup for search engines. A past edition stays on the directory as the series' record, marked past, with no markup, until the organiser publishes the next dates. A cancelled edition is removed and noted on the series' next listing when there is one.

Re-checking

Listings are re-read against their source page before each edition's month begins and whenever an organiser writes in. A change on the organiser's page changes the listing and moves the verified date. If a source page disappears, the listing is marked past or removed rather than kept on memory.

Paid listings

A featured placement (see partnerships) changes where a listing sits, never what it says. Paid or not, a listing passes the same four checks, and a paid one is labelled "sponsored listing" in the row and on its page.

Corrections

Organisers and readers can send a correction, with the listing URL, to the contact address, which is published on this site once its mail is set up (it is not yet). The correction is applied when the organiser's own page shows it.
