Deprecated by !x-orgversions, which is part of [[LSL_Protocol/Restrained_Life_Open_Relay_Group/ORG_Requirements|ORG core requirements]].
STATUS: Up for discussion, but near final
 
VERSION: Draft 1 (version string: 001)
 
''Implemented in OpenCollar and in Satomi's Multirelay HUD''
 
; Description : Queries the relay to discover the list of supported x-tensions; this way devices can query the relay for supported x-tensions and make use of them or not as they choose.
 
; Implementation : Returns the list of ORG extensions implemented in the relay
 
; Syntax : '''!x-tensions'''
; Response : '''!x-tensions,<reply>'''
:: where '''<reply>''' is a list of x-tensions, separated by / where each extension is listed with a version number
 
; Example:
-> blah,k(R),!x-tensions
<- blah,k(C),!x-tensions,core=1100/xtensions=001/vision=002/listen=001/email=005/channel=002
 
 
; Key points
The relay should answer, in the acknowledgement field by the list of supported x-tensions, separated by slashes "/", followed by the version of the specification of the extension which is implemented (after a vertical bar "|"). Note that only the x-tension names are given, not meta-command names (email extension has 3 meta-commands, for instance). Note that extension names do not contain the "!x-". Versions numbers are 3 digits.
 
One required response is ''core''. "core" is the core RLVR protocol (as defined by Marine Kelley), and its version number is 4 digits (where all the other components have only 3), that are the same as those returned by !version. In some cases where the furniture doesn't wan't to speak to non-ORG relays, this can spare a !version request.
 
Also another required response is ''xtensions''. While it seems unlikely that the protocol would change, not responding with ''xtensions'' and a version number will make it impossible to make any substantive changes should they prove necessary.
 
 
; Discussion
 
I changed the 3rd level separator from "|" to "=", only for readibility reasons. Please tell me if you think it was a poor choice.--[[User:Satomi Ahn|Satomi Ahn]] 12:03, 3 July 2009 (UTC)
 
And what about not-yet validated or proprietary RLVR extensions? Should we recommend adding them to the !x-tensions reply? Maybe with negative version numbers?--[[User:Satomi Ahn|Satomi Ahn]] 12:19, 3 July 2009 (UTC)
