Metro Signage Server

July 2016 | Douglas Goodwin

There are three parts to this application:

1. XML export from Outlook
2. Python XML parser and JSON emitter
3. JSON API and Websocket server

Part 1 publishes current meetings scheduled in Outlook as an XML feed.

Part 2 GETs the XML, parses and converts it to JSON then POSTs the JSON to Part 3.

Part 3 parses the JSON and pushes content to the clients over websockets.

Try it out!

git clone https://github.com/LACMTA/eventsignage.git
cd eventsignage
virtualenv .
pip install -r requirements.txt

# set up your secret variables by editing mysettings.py
cp mysettings.py.SAMPLE mysettings.py

Run Part 3: the Tornado API and websocket server

# start the server on 127.0.0.1:8888
python app.py

Open a new terminal window and send some test events from Part 2.

cd part_2 ;
python fetch_parse_emit.py

Et voilà!

You should now see random Metro-flavored events cycle in the browser. Woo!
