3. Extensions in Wave
The most common ways to extend Wave are to use:
• Gadgets
o Embed them in a conversation
o Built with HTML+Javascript
o Interactive with the Wave and it’s participants
o Ex: maps, slideshows, search results
• Robots
o Are actual participants of a Wave which can ‘do things’
Exactly the same as a Wave participant
o Ex: content update, integration with other systems

4. Wave Entities: Data Model
“Show me your flowchart and conceal your tables, and I shall continue to be mystified.
Show me your tables, and I won't usually need your flowchart; it'll be obvious.”
Fred Brooks, The Mythical Man-Month
• Wave
• Wavelets
• Blips
• Documents

6. Wave Robot Concepts
• Wave Robots...
o Live in the cloud.
o Are external (robotic) participants.
o Have full access to wave.
o Respond to events on a wave.
o Are currently available for Java and Python APIs on
Google App Engine.

7. Wave Robots Essentials
• APIs in Python and Java
• Runs in Google App Engine
• Events:
o "Robot added to Wave" - WAVELET_SELF_ADDED
o ”New blip" - BLIP_SUBMITTED
o "Blip edited" - BLIP_VERSION_CHANGED
o "New participant"
- WAVELET_PARTICIPANTS_CHANGED
• Responds to:
o Augmented or edited Wave content
o Invites from other participants
o Interaction with other systems outside of Wave

8. Robot Examples
Smiley
"""Smiley: Yet another smiley robot."""
from waveapi import events
from waveapi import robot
def OnBlipSubmitted(properties, context):
blip = context.GetBlipById(properties['blipId'])
contents = blip.GetDocument().GetText()
contents = contents.replace(':(', unichr(0x2639)) # happy
contents = contents.replace(':)', unichr(0x263A)) # sad
blip.GetDocument().SetText(contents)
if __name__ == '__main__':
smiley = robot.Robot('Smiley')
smiley.RegisterHandler(
events.BLIP_SUBMITTED, OnBlipSubmitted)
smiley.Run()
(A complete and useful robot in a single slide... with
room to spare!)
