This informational document defines a human readable ASPA notation for Validated ASPA Payloads (VAPs) [I-D.ietf-sidrops-aspa-profile].¶
The main motivations for providing this notations style are: * This can help to create consistency between RPKI Relying Party software output, making it easier for operators to compare results. * This can be used by RPKI Certificate Authorities (CA) command line interfaces and/or configuration. E.g. allowing a CA to provide a listing of intended VAPs which can be easily compared to RP output. * This can be used for documentation.¶
That said, this definition is informational. Implementations can choose to use their own notation styles instead of, or in addition to this.¶
This specification uses ABNF syntax specified in [RFC5234].¶
