[Olympus developers 25]: Re: [Fwd: binding filters]

[Antoine Raux]

I completed the Binding Filters section in the Wiki 
(http://wiki.speech.cs.cmu.edu/olympus/index.php/RavenClaw_Grammar_Mappings_and_Binding_Filters#Binding_Filters).
It should now give a pretty good idea of what binding filters are and 
how to use them (at least I hope so...).

BTW, the MeetingLine system as it stands now does not use the datetime 
binding filter (it is declared in the CORE_CONFIGURATION and the 
function exists, but no grammar mapping uses ">:datetime"), which partly 
led to the confusion. I see that Thomas has just removed all the binding 
filter code from the MeetingLine repository, which is good :)
