Ok, so I misunderstood the RFC6486:

"A manifest is a signed object that enumerates all the signed objects
(files) in the repository publication point (directory) that are
associated with an authority responsible for publishing at that
publication point."

RFC6488:
"Other information assertions about
resources are expressed via digitally signed, non-X.509 data
structures that are referred to as "signed objects" in the RPKI
context."

So, in the first sentence, "signed object" means all files which were signed by the CA instance and not a RPKI signed object as in the second one?!

Thank you for your answers.

Kind regards

CA certs are listed by the manifest that sits in the same publication
point (directory).  In addition, the cert's SIA contains a URI for all
of the "children."  If the CA cert were present but "all files
underneath" were missing, the RP software would at the very least log a
failure to fetch the child directory.


    ... a Router certificate, the RP WOULDN'T recognize it, because it

A manifest will cover anything in the directory (except itself), so that
should include router certs.
