This service serves a curated catalogue of attestation rulebooks that the registration application consults when a Relying Party declares which credentials it will request from wallets.
The rulebook definitions served here are derived from the webuild-attestation-rulebooks-catalog by parsing that catalogue's markdown source. Each rulebook is a trimmed projection of the original: only the information needed to support Relying Party service registration is included — attribute paths per format, the mandatory / optional / conditional classification, and presentation labels. Content in the source catalogue that is not relevant for this purpose, such as protocol descriptions, encoding details, trust anchor arrangements, and credential envelope claims, has been left out.
The current snapshot was taken on 2026-09-25 and does not reflect any changes made to the source catalogue after that date.
