Methodology

How this site is written and verified

Every legal claim on this site traces to a source in a public registry, fetched and dated. If we have not read it, we do not state it. If it is unknown, we say “Unknown”.

The source registry

The site keeps a single registry of sources (content/sources/registry.yaml in the site’s public repository). Each entry records the instrument’s full title, its ELI identifier, the canonical URL, its Official Journal reference, and the date we last retrieved it. Inline citations resolve against this registry; a citation to an unregistered source fails the site’s build. The full registry is published at /sources.

Source hierarchy and labels

Claims are labelled by the strength of what supports them, in this order:

1. Law — text published in the Official Journal (directives, regulations, implementing acts), read on EUR-Lex.
2. Proposal — Commission proposals and policy pages. Not law. May change or fail. Always labelled.
3. Technical draft — specifications such as the EUDI Wallet Architecture and Reference Framework. Not law, and revised without an OJ publication.
4. Implementation note — engineering experience from building against these rules. Clearly ours, clearly not law.
5. Commentary — everything else, including our own analysis. Never the sole support for a date or an obligation.

Two standing rules follow from this. A law firm’s blog post is never the only support for a date. And the word “must” appears on this site only where an instrument imposes the obligation.

Verification cycle

Every explainer records when it was published, when it was last verified, and against which retrievals. Each page has a review cycle (typically 30 days). If a page has not been re-checked within its cycle, it displays a “Verification overdue” notice — automatically, because a stale page that admits it is stale is safer than one that does not. A weekly source pass re-fetches the key instruments; if nothing changed, retrieval dates are bumped, and if something did change, the affected pages are edited and their changelogs record what changed in the law.

What we do not do

• We do not state article numbers, dates, or transposition statuses from memory or from secondary sources.
• We do not mark a Member State as having transposed until we have seen the measure in that country’s official gazette.
• We do not give legal advice, and we do not tailor content to advertisers — there are none.

Corrections

Errors are corrected publicly. The correction is recorded in the page’s changelog stating what was wrong and what it was corrected to. To report an error: hello@eudipoa.com.
