[db-wg] Proxy proposal large communities

Dear Working Group,

As discussed at RIPE 75 I want to forward a request by Job Snijders on GitHub:
https://github.com/RIPE-NCC/whois/issues/410

Job is asking to add a “large_community" keyword to RPSL dictionary where applicable.

And provides the following example:

Suggestion: name the keyword large_community

mp-export:      afi ipv6.unicast to AS13105 announce AS-RCNET-V6 AND NOT large_community.contains(21414:0:570)
export:         to AS6777 action large_community .= { 6777:0:6777 }; announce AS-FORTHNET
mp-import:      afi ipv6.unicast from AS8631 msk-rs2.ripn.net action large_community={31376:0:2}; pref=100; accept AS-MSKROUTESERVER
import:         from AS35082 95.128.51.234 at 95.128.51.233 action pref=500; large_community.append(29527:0:35082,29527:0:60000,29527:0:61200,29527:0:61210); accept AS-VIBUS-LONDON


filter-set:     fltr-as21229-export
descr:          Filter for AS21229 exported prefixes
filter:         AS-TVNETWORK AND large_community(21229:0:1)


From our end I do not see any issues implementing this on the server side, but I can’t speak to how this will be treated by scripts that may parse RPSL today.

Please discuss.

Kind regards,
