Citing the index
The register index is meant to be quoted, disputed and used as evidence. It is published under CC0, so no permission is needed and no attribution is owed. This page exists because a citation is more useful to your reader when it carries a date.
What to cite
Cite the row rather than the table when the claim is about one register, because the row carries the authority, the source address and the date it was checked. Cite the index when the claim is about the pattern.
Every row records the day somebody looked. That date matters more than the publication date of the index, because a register can change the week after it is checked and this lab would rather be corrected than assumed current.
If a row is wrong, the correction is published beside it with its date, and the original stays visible. An index that quietly edits itself is not evidence.
A worked citation
For the index as a whole:
Revow register index, 54 registers across 37 jurisdictions.
Revow, an open lab. Checked by hand, 9 to 10 November 2026.
CC0 1.0. https://revow.org/#registersFor a single row:
"Austria replaced fourteen provincial trade registers with one national
system in March 2015 and still publishes no file."
Revow register index, AT, licensed trade business. Checked 10 November 2026.
https://revow.org/#r-at-licensed-trade-businessReplace the fragment with the row you are citing. Every row on the index has its own address.

If you are writing about this
The most checkable claim in the index is the one that has held through every pass: no authority anywhere in it publishes a signed file. 50 of 54 publish a page per licence, 16 publish a bulk export, and none sign anything.
The second is that the gap is not technical. Several of the authorities surveyed have already issued signing keys to the professionals they regulate, and still publish nothing signed themselves.
What this lab would rather not see written is that Revow verifies credentials. It does not. It makes a claim checkable and a lie permanent, and it says so on every page that could be misread.
