Dear colleagues,
As you may know, the RIPE NCC publishes daily RPKI dumps for all trust anchors
on ftp.ripe.net/rpki. Today, we have made some changes to this longitudinal
dataset.
We have added:
* The compressed JSON output of a validator (output.json.xz). We added this
because it contains validated ASPA and BGPsec payloads.
* A compressed version of the CSV file of ROAs (roas.csv.xz)
* A xz compressed archive of the validated and unvalidated objects (repo.tar.xz)
We made this change because it significantly reduces the size of the files. At
this point, we do not plan to re-compress historic files. However, to realise
the savings, we must stop producing the larger version at some point and clean
up the "duplicate" files from the transition period.
For now, we will create the old (roas.csv, repo.tar.gz) and new (roas.csv.xz,
repo.tar.xz) side by side during a transition period. We plan to stop creating
the old format after a transition period of at least a month, taking into
account the feedback we receive. We will inform you when this happens.

Dear colleagues,
The next quarterly plans for RPKI are now published:
https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan…
This quarter, we’ll continue with our activities on building an audit framework
for RPKI, open-sourcing our internal RPKI monitoring and making improvements to
the RPKI dashboard. We also plan to migrate to new online HSMs.
The aim of sharing these plans is to inform you of the ongoing work on RPKI and
get your feedback. If you have any comments or questions, we hope you'll discuss
them with us on the list or by contacting the team directly at rpki(a)ripe.net.
Kind regards,
Ties de Kock
Specialist Software Engineer
