Samples

What people receive, shown on made-up examples

Every certificate, card, badge and page here is drawn by the same code that draws the real ones, for a made-up contributor, company and projects. Each says inside the drawing that it is a sample, and none of them is valid anywhere.

A sample has no signature, no entry in the transparency log and no published record. Its code opens a page that says it comes from a sample; a real certificate's code opens its own page on /verify, the only place a certificate is checked.

What a contributor receives

The made-up contributor is Anouk Samplewood, @psn-sample-anouk, credited by 3 made-up projects. When a registered project credits a real contributor, the certificate names that contributor's own login and projects, if they choose to show them.

We do not show a sample contributor certificate here yet, because its final wording is not published. Its badges have no wording of their own, so you can see them now.

Sample: the certificate's badges, for a README or a profile. A badge names nobody; on a real certificate it links to the certificate's own page on /verify. Contributor certificates are not issued here yet.

What a company receives

The made-up company is Vellumbrook Data GmbH. When it pays the Purpose Fee for a project, it receives a payment certificate; if it chooses to be listed, the certificate has a share card that names it.

What a maintainer receives

The made-up project is psn-sample/atlas. A registered repository has a badge for its README and a project card for sharing. They state its registration, never who contributed.

What happens when you scan a sample's code

It opens a page of ours that says the code comes from a sample, and nothing else: no verdict, no fingerprint, no record. A real certificate's code opens its page on /verify, where its signature is checked in your browser.

The GitHub names a sample shows (psn-sample, psn-sample-lab, psn-sample-anouk) are held by us as empty GitHub organisations, so none of them can belong to someone else. The contributor's and the company's names are made up. When they were chosen, the company's name was checked against company and trade-mark registers, and the contributor's against trade-mark registers and the web.

Every sample on its own page
