Article 7: Creation and maintenance of the catalogue of attributes
The Commission shall establish and publish a catalogue of attributes and set up a secure system to enable requests to include or modify attributes in the catalogue of attributes.
The Commission shall assess requests made using the system referred to in paragraph 1 to include or modify an attribute in the catalogue of attributes, after considering any advice provided by the Cooperation Group. The Commission's assessment shall, take into account whether the inclusion of the attribute contributes to a common foundation for secure and privacy-aware electronic interaction between citizens, businesses and public authorities and to fostering interoperability. The Commission shall also take into account sector-specific regulations, where applicable.
Member States shall request the inclusion of attributes listed in Annex VI to Regulation (EU) No 910/2014 to the catalogue of attributes wherever those attributes rely on authentic sources for the purpose of the verification by qualified trust service providers.
In addition, Member States may request the inclusion of attributes not listed in Annex VI to the catalogue of attributes wherever those attributes rely on authentic sources within the public sector. Private entities that are considered to be a primary source of information or recognised as authentic in accordance with Union or national law, including administrative practice, may request the inclusion of attributes not listed in Annex VI to the catalogue of attributes wherever the requesting entity is responsible for those attributes.
The request to include or to modify an attribute in the catalogue shall contain at least the following information:
(a) identification of the entity making the request;
(b) where applicable, a reference to Union or national law or administrative practice under which the entity making the request is considered to be a primary source of information or recognised authentic source.
(c) if the request refers to an attribute already existing in the catalogue or is a new attribute;
(d) a namespace for the identifier of the attributes, the value of which is unique within the catalogue of attributes;
(e) an identifier of the attribute, unique within the namespace, and the version of the attribute;

(h) the verification point for the attribute at national level or a link to a description on how to initiate the verification requests.
The request to include or modify an attribute shall be signed or sealed by the requester by means of a qualified electronic signature or seal or an advanced electronic signature or seal based on a qualified certificate.
The Commission, following the assessment referred to in paragraph 2 and having verified that the information provided in the request for the inclusion or modification of an attribute includes all the information listed in paragraph 5, may include the requested attribute or modification in the catalogue of attributes.
The catalogue of attributes sealed by the Commission shall be publicly accessible, through a secure channel, free of charge and without prior identification or authentication, and shall be published in both machine-readable and human-readable forms. The catalogue shall also include a search function.
The Commission shall publish the technical specifications the Commission uses for the catalogue of attributes.
The Commission shall issue a unique identifier to each registered attribute.
Article 8: Creation and maintenance of the catalogue of schemes for the attestation of attributes
The Commission shall establish and publish a catalogue of schemes for the attestation of attributes and set up a secure system to enable requests to include or modify schemes for the attestation of attributes in the catalogue of schemes for the attestation of attributes.
Requests to include or modify schemes for the attestation of attributes in the catalogue of schemes for the attestation of attributes shall be assessed by the Commission, after considering any advice provided by the Cooperation Group. The Commission's assessment shall take into account whether the scheme contributes to a common foundation for secure and privacy-aware electronic interaction between citizens, businesses and public authorities and contributes to fostering interoperability. The Commission shall also take into account sector-specific regulations where applicable.
Owners of a scheme for the attestation of attributes may request adding schemes to the catalogue of schemes. A request to include or modify a scheme in the catalogue of schemes for the attestation of attributes shall contain, at least:
(a) the name of the scheme, chosen by the scheme for the attestation of attributes owner and unique within the catalogue of schemes for the attestation of attributes;
(b) the name and contact information of the scheme for the attestation of attributes owner;
(c) the status and version of the scheme;
(d) a reference to specific laws, standards or guidelines, where the issuance, validation, or use of an electronic attestation of attributes within the scope of the scheme is subject to them;
(e) the format or formats of electronic attestation of attributes within the scope of the scheme;
(f) one or more namespaces, attribute identifiers, semantic descriptions and data types of each attribute that is part of an electronic attestation of attributes within the scope of the scheme, either by reference to an attribute in the catalogue of attributes in Article 7, or an attribute defined in an analogue way within the scope of the scheme;
(g) a description of the trust model and the governance mechanisms applied under the scheme, including the revocation mechanisms;
(h) any requirements concerning the providers of the electronic attestations of attributes or the sources of information on which those providers rely when issuing electronic attestations of attributes, including any authentic sources, if applicable;
(i) a statement whether electronic attestations of attributes within the scope of the scheme are to be issued as qualified electronic attestations of attributes, as electronic attestations of attributes issued by or on behalf of a public sector body responsible for an authentic source, or as both.
The schemes for which inclusion in the catalogue is requested shall only contain attributes that are identifiable based on unique identifiers. The request to include or modify a scheme for the attestation of attributes shall be signed or sealed by the requester by means of a qualified electronic signature or seal or an advanced electronic signature or seal based on a qualified certificate.
The Commission, following the assessment referred to in paragraph 2 and having verified that the information provided in the request for the inclusion or modification of an attestation scheme contains all the information listed in paragraphs 3 and 4 may include the requested scheme or modification in the catalogue of schemes for the attestation of attributes.
The catalogue of schemes for the attestation of attributes, sealed by the Commission, shall be publicly accessible, through a secure channel, free of charge and without prior identification or authentication, and shall be machine-readable and human-readable. The catalogue shall also include a search function and shall be in a format that guarantees integrity and authenticity.
The Commission shall publish the technical specifications the Commission uses for the catalogue of schemes for the attestation of attributes.
The Commission shall issue a unique identifier to each registered scheme for the attestation of attributes.
Article 9: Verification of attributes against authentic sources or designated intermediaries
To enable the electronic verification of the attributes referred to in Article 45e(1) of Regulation (EU) No 910/2014 by qualified trust service providers issuing qualified electronic attestations of attributes, at the request of the user, Member States shall establish mechanisms that allow that verification and may make available single points of verification for the attributes listed in Annex VI of that Regulation wherever those attributes rely on authentic sources within the public sector. Member States shall publish information on the procedures for initiating the verification requests and for receiving the verification results.
The verification mechanism shall provide an access point where qualified trust service providers issuing qualified electronic attestations of attributes can electronically request the verification against authentic sources or designated intermediaries recognised at national level, of the attributes referred to in Article 45e(1) of Regulation (EU) No 910/2014. Attributes subject to verification will be provided to the verification point by the qualified trust service provider at the user request. The public sector body or designated intermediary shall share, through the verification point, the verification results with the qualified trust service providers issuing qualified electronic attestations of attributes.
The verification request shall set out the attributes and the identification data of the subject of the attribute for which the qualified trust service provider requests the verification.
The verification result shall state exclusively whether the attribute has been verified or not and specify the public sector body responsible for the authentic source or, where applicable, the public sector body designated to act on behalf of the authentic source against which the attribute has been verified.
Member States may impose access controls or other verification mechanisms that provide integrity, authenticity, and confidentiality to determine that the requester is a qualified trust service provider and is acting at the request of a legitimate user. Member States may also impose control mechanisms on the use of the verification methods, where they deem this appropriate, taking into account relevant factors, including whether the authentic sources contain personal confidential or sensitive data. Where Member States establish these control mechanisms, they shall publish information on the extent of the control mechanisms as part of the information referred to in paragraph 1.
Article 10: Interoperability and reuse
For the purpose of Articles 3 to 9, Member States may refer to and re-use the common services of the technical system set out in Article 14 of Regulation (EU) 2018/1724, as well as the national components connected to them.
When establishing the secure notification system and the list of public sector bodies referred to in Articles 5 and 6 and the catalogues referred to in Articles 7 and 8 of this Regulation, the European Commission shall refer to and re-use, where appropriate, the common services of the technical system pursuant to Regulation (EU) 2018/1724.
Article 11: Entry into force and application
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.
This Regulation shall be binding in its entirety and directly applicable in all Member States.
