Reducing the data and focusing on BGP route outcomes as the primary use case 
will be helpful.

As you note, there is some room for providing summary data to help correlate 
how RPKI-RTR state is being used for validation will be helpful for the core 
BGP data.  To provide an example, CCR hash values - when they become commonly 
implemented - can be helpful for a BMP consumer to know what version of the 
database is being used to validate the routes.  However, CCR will require some 
time to mature and become commonly available state.

Meanwhile, as some of the draft covers, being able to verify that RPKI 
validation is available and whether it has been done for a given route is an 
excellent use case.  The supporting information to report how that validation 
was enabled (RPKI-RTR is up, it has X version of the DB, this BGP session is/is 
not validated, validation extended communities are present) is useful - if we 
can make the information dense enough.

I'm looking forward to the presentation.
