[regext] Re: Extension Identifiers in draft-ietf-regext-rdap-rir-search

[Mario Loffredo <[e-mail]>]

Hi Scott,

sorry  but didn't undenstand your example about collisions.

 From a conceptual perspective, any path "/domains/...." is a subpath 
(we can consider it as an extension) of "/domains" but, 
programmatically, they are different as AFAIK a full path is parsed and 
processed altogheter.

For example, in .it RDAP server, I have leveraged the feauture provided 
by a Java framework to specify paths and their subpaths in order to 
easily map an incoming request onto but, at the end of the parsing 
phase, only one full path is selected.

Therefore, IMHO, there is no risk of collisions.


Best,

Mario
