9. Gaia-X Power of Attorney format¶

To adapt to various organisation structures and introduce a mean for a party to delegate rights to another party, a power of attorney is useful.

A Gaia-X Power of Attorney is a machine readable, structured and signed document that comprises at a minimum the following information attributes:

• Power of Attorney ID, as unique identifier.
• Principal ID, as unique identifier for the Participant that signs the power of attorney.
• Principal cryptographic material reference, to enable the verification of the signature of the power of attorney.
• Authorised Participant ID, as unique identifier for the Participant to whom the powers are granted.
• Authorised Participant cryptographic material reference, to enable the verification of the signature of future claims signed by the Authorised Participant.
• A list of granted powers, either as text or preferably in a machine-readable format using a Domain Specific Language (DSL) like ODRL.
• Issuance date on which the power of attorney was issued.
• Validity start and end dates on which the power of attorney enters into force and will expire.
