Subject: Re: [emergency] CAP Visualization (was RE: CAP Developers' Forum...)
Kwasi,
Sounds like a nice application - I'm curious as to which CAP fields
you use to filter messages of interest. For example, did you get
anywhere trying to filter on the <event>, or did you fall back on
a set of system-specific <eventCode> values?
TIA,
-jeff
