Why build on Google Wave?

• Real-time == Real-awesomeo Self-explanatory

• Workflowo Focused on bridging communication and workflow.

• Leverageo New and exciting technology and foundation.

• Opportunity!o New business opportunities.

Extensions in Wave

• Gadgetso Embed them in a conversationo Built with HTML+Javascripto Interactive with the Wave and it’s participantso Ex: maps, slideshows, search results

• Robotso Are actual participants of a Wave which can ‘do things’

Exactly the same as a Wave participanto Ex: content update, integration with other systems

The most common ways to extend Wave are to use:

Wave Entities: Data Model

• Wave• Wavelets• Blips• Documents

“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

Robot Architecture Overview

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.

 

Wave Robots Essentials

• APIs in Python and Java• Runs in Google App Engine• Events:

o "Robot added to Wave"  - WAVELET_SELF_ADDEDo ”New blip"  - BLIP_SUBMITTEDo "Blip edited"  - BLIP_VERSION_CHANGEDo "New participant" 

- WAVELET_PARTICIPANTS_CHANGED• Responds to:

o Augmented or edited Wave contento Invites from other participantso Interaction with other systems outside of Wave

Robot Examples

Smiley

"""Smiley: Yet another smiley robot.""" from waveapi import eventsfrom 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!)

Other Robot Examples

• Swedish Chef• Monty + Syntaxy (a match made in robot heaven)• Wikify (wikifier@appspot.com)• CleanTXT (cleantxt@appspot.com)• Polly the Pollster (polly-wave@appspot.com)• Yelpful (yelpful@appspot.com)• TwitUsernames (twitusernames@appspot.com)• XMPP Lite (wave-xmpp@appspot.com)• Madoqua Wave Bot (blog-bot@appspot.com)• Emoticony (emoticonbot@appspot.com)• Inbeddable (inbeddable@appspot.com)• Easy Public (easypublic@appspot.com)

Robot Roadmap

• New Robots wire protocol (v0.2)o Publish for community feedbacko Implement Java and Python API parity

• Internal speed improvements for AppEngine robots. • Robot Gateway / OpenSocial REST Access• Robot access to OAuth controlled resources• Better multiple wave access• Sunset robot cron in favor of direct access to Wave

servers.• Gateway support: Improve the current tweety type of

access to support outside addresses of the form address+robot@appspot.com

Beyond Robots: Wave federation
