TS11
TS11 is the European Commission technical specification, version v1.0.1 (2026-01), that defines the data models and HTTP interfaces for the two Commission-run catalogues that anchor the EUDI Wallet ecosystem: the catalogue of attributes, where member states register attribute definitions, and the catalogue of Attestation Rulebooks, where issuers register the machine-readable metadata that points to their credential schemas.
The two catalogues serve distinct purposes and are easy to conflate. The catalogue of attributes answers what a given attribute identifier means: its data type, its authentic source, and which member states report it. The catalogue of Attestation Rulebooks answers what a given credential type contains: which schemas it can appear in, which formats it supports, which trust authorities it relies on, and what level of assurance it meets. An issuer that wants to be discoverable registers a SchemaMeta entry in the catalogue; a verifier that encounters an unfamiliar credential type queries the catalogue to find the rulebookURI and the schemaURIs it needs to validate what it received. The public read API needs no authentication: GET /schemas returns a filtered, paginated list and GET /schemas/{schemaId} returns a single record. Write access is restricted to an authorised representative of the entity that owns the record. TS11 is an interim Commission specification; ETSI is developing EN 319 482-3 on the same basis, with an expected publication date of 2027-10-31.

Who registers entries in the TS11 catalogues?
Member states and authentic sources register attribute definitions in the catalogue of attributes; issuers register SchemaMeta entries pointing to their credential schemas in the catalogue of Attestation Rulebooks. Both registrations are mediated through the European Commission's infrastructure and require authorisation; they are not self-service.
