Hi,

Based on the discussion of splitting up the voucher handling endpoint naming 
issues from BRSKI-AE today, I just wanted to ensure I got the way forward 
right.

What we discussed in the WG meeting was to have a separate short document, 
basically defining a renaming or alternatively an alias for the current 
endpoints, which allows to keep the current implementations as is. 
Hence, the draft would relate to all of the endpoints defined in section 5 of 
BRSKI for the domain registrar facing the pledge (and potentially also the 
MASA), which are: 
/.well-known/est/requestvoucher used by pledge to registrar but also from 
registrar to MASA
/.well-known/est/voucher_status used by pledge to registrar
/.well-known/est/requestauditlog        used by registrar to MASA
/.well-known/est/enrollstatus           used by pledge to registrar

Eliot stated that there are already implementations out there that utilize the 
/est approach. So having aliases could be one way of dealing with it, but this 
would double the endpoints at least for the four stated ones above. 

Both approaches have there merits. Having the endpoints distinct from the 
beginning allows a clearer separation of the functionalities, for the pledge 
and for server side handling. Specifically if we later on allow for alternative 
enrollment protocols in BRSKI-AE and define the discovery approach, it will 
lead to less confusion to align the naming with the corresponding 
functionality. From that perspective, my gut feeling would be that an 
integration into base BRSKI may be more appropriate. On the contrary, it will 
slow down the process, but somebody stated that there are examples that these 
changes have been also done in the past and could be done fast. 

What do you suggest as way forward? 

Best regards
Steffen
