What you can change, how to send it, and what happens after you do
This page answers three things: which layer you are allowed to change, how to send a change, and what happens once you have sent it.
Which layer you can change
Every page is written in three layers, and each layer has a different rule about who may write it.
-
Fact layer: corrections
Who: Anyone.
Company name, exhibit zone, hall, booth number, years exhibited, official links. These are extracted mechanically from the public exhibitor directory, so they go wrong in exactly the ways a directory goes wrong: stale entries, renamed companies, moved booths.
Condition: Every correction needs a source link: the official directory, the company site, or a public press release. A correction without a source is not applied.
-
Claiming your own page
Who: An employee or authorised representative of the company the page is about.
Fill in fact-layer fields the directory left blank, correct what is wrong, or ask for the whole page to be taken down.
Condition: Claiming costs nothing and changes nothing about how the page is ordered or displayed. There is no paid tier.
-
Curation layer: objections
Who: Anyone may object; only neutral editors may write.
Where a company sits in the industry, what changed year over year, how it compares with others in the same zone. These are judgements, not directory fields.
Condition: A company can object and ask for the objection to be recorded on the page, but cannot dictate what the curation layer says. That boundary is what the site is worth.
How to send it
Email is the only route right now. Include these five things so the correction can be checked without a follow-up round trip.
- The page URL
- Which field, or which sentence
- What it should say
- A source link: official directory, company site, or press release
- Who you are: company representative or reader (optional)
Opens your mail client with the five fields pre-written. Type over them.
Or send a pull request
The source and the data are public. Every page is one Markdown file under knowledge/, so a correction is a one-line diff. A pull request is the only write path into the repository, and merging stays with a human: that boundary is the design, not a limitation.
What happens after you send it
-
The source you sent is checked against what the page currently says.
-
If it matches, the field is changed and its checked date is set to that day.
-
If it does not match, or the source is not enough to carry the claim, you get a reply explaining why. Nothing is silently dropped.
-
A takedown request is honoured. A short note is left at the original URL: the page is not made to look as though it never existed.
Four things this site does not do
A multi-party archive is only worth reading if the rules still hold when someone with a budget asks. So they are written as flat negatives.
- No payment changes any ordering, marker, or presentation. There is nothing here to buy.
- No marketing copy is written or reprinted here. Material supplied by a company does not go up as-is.
- The curation layer takes no dictated content, from anyone.
- Numbers the organiser has not published are not inferred, and not reconstructed from elsewhere. Blank stays blank.
Not open yet
One thing is designed but not available. It is listed here so this page does not imply more than exists.
- Booth Score
- A completeness score computed mechanically from field coverage, source coverage and freshness, where marketing copy earns zero. The rule is settled; the implementation is not written. There is no ranking on the site today.
