ICAO Implementation differs from vaccination implementation

[jona7o]

Hi,

we are a software development company with a product for COVID19 test- and vaccination centers. For this use case we create both, vaccination certificates over ubirch/ibm api and test certificates over the cwa endpoint. Today I found a miss match between these two certificates for the same input.

I think this bug is located in the ubirch/ibm api because i think the dot char "." is not specified for a machine readable string and gets replaced by nothing and not with an "<" char. If it is defined this is a bug in the reference implementation of the cwa. I'll open these requests in both github repositorys and link each other. Could someone clarify which implementation is correct?

Example for Vaccination certificates with Ubirch/IBM API:
"fn": "Dr. Mustermann",
"gn": "Max",
"fnt": "DR<<MUSTERMANN",
"gnt": "MAX"

Example for Test over CWA API
"fn": "Dr. Mustermann",
"gn": "Max",
"fnt": "DR<MUSTERMANN",
"gnt": "MAX"

Regards, Tobias

Not a bug in CWA. Should be fixed for certifications APIs.
