The Common Alerting Protocol is a lightweight standard to facilitate the distribution of alerting data. RCAP is an implementation of the CAP in Ruby. It allows for the creation of RCAP messages from Ruby applications and the parsing of external messages.
RCAP currently supports CAP 1.0, 1.1 and 1.2.
RCAP is distributed as a Ruby gem and is available from Rubygems.org.
gem install rcap
The gem is also available for download and manual installtion at http://www.aimred.com/gems.
require 'rcap' alert = RCAP::CAP_1_2::Alert.new do |alert| alert.sender = 'firstname.lastname@example.org' alert.status = Alert::STATUS_ACTUAL alert.msg_type = Alert::MSG_TYPE_ALERT alert.scope = Alert::SCOPE_PUBLIC alert.add_info do |info| info.event = 'Liquid Petroleoum Tanker Fire' info.language = 'en-ZA' info.categories << Info::CATEGORY_TRANSPORT info.categories << Info::CATEGORY_FIRE info.urgency = Info::URGENCY_IMMEDIATE info.severity = Info::SEVERITY_SEVERE info.certainty = Info::CERTAINTY_OBSERVED info.headline = 'LIQUID PETROLEOUM TANKER FIRE ON N2 INCOMING FREEWAY' info.description = 'A liquid petroleoum tanker has caught fire on the N2 incoming freeway 1km after the R300 interchange. Municipal fire fighting crews have been dispatched. Traffic control officers are on the scene and have diverted traffic onto alternate routes.' info.add_area do |area| area.area_desc = 'N2 Highway/R300 Interchange' area.add_geocode do |geocode| geocode.name = 'Intersection' geocode.value = 'N2-15' end end end end puts alert.status # "Actual" info = alert.infos.first puts info.language # "en-ZA" puts info.categories.join( ', ' ) # "Transport, Fire" puts info.areas.first # "N2 Highway/R300 Interchange"
