Google Maps API

What is it?• Put Google Maps on your site for free, just like Frappr.com,

housingmaps.com and chicagocrime.org• Overlay custom content, write custom functionality• Free to all web sites that are free to consumers (including commercial

web sites)• V1 in june 2005, V2 in April 2006• Maps for Enterprise

o Behind the firewall mashupso Phone supporto Geocoding backend for many locations

So how does Maps do work?

Maps JavaScript architecture

CSS positioned map tiles with a cropped at the map border

What you can do with the Google Maps API

Switch between maps• “Map”, “Satellite” and “Hybrid” modes supported by default

Overlays• Markers

o Custom icons, shapes, etc• Polylines

o e.g., driving directions lines• Custom overlays

“Info window”, tabbed• You know, that cool window with the shadow underneath it

Customizability• Custom map controls, overlays, and map types

Overview map• New GOverviewMapControl control displays an attractive and collapsible map in the

corner of the screenSupport for a subset of KML (Google Earth data format)

Emphasis on Simplicity

// Center the map on Westin Hotel in San Franciscovar map = new GMap2(document.getElementById("map"));map.addControl(new GSmallMapControl());map.addControl(new GMapTypeControl());map.setCenter(new GLatLng(37.787742,-122.408295), 13);// Add 10 markers to the map at random locationsvar bounds = map.getBounds();var southWest = bounds.getSouthWest();var northEast = bounds.getNorthEast();var lngSpan = northEast.lng() - southWest.lng();var latSpan = northEast.lat() - southWest.lat();for (var i = 0; i < 10; i++) {var point = new GLatLng(southWest.lat() + latSpan * Math.random(),southWest.lng() + lngSpan * Math.random());map.addOverlay(new GMarker(point));}

Google Ajax APIs

Standard REST Plumbing for Google APIs

Each service wants their own Data API: standardize on a common REST Plumbing• APIs = Plumbing

"If I had my life to live over again, I'd be a plumber.”

Albert Einstein

Google Data API

REST API, Based on Atom and the Atom Publishing Protocol

"The release of atom power has changed everything except our way of thinking…”

Albert Einstein

+ Google namespaced service specific Data+ AuthSub+ Optimistic Concurrency

First Google Data API: Calendar

GET, POST, PUT, DELETE Calendar EntriesReleased in April 2006

“...the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker."

Albert Einstein

20 AtomPub based Data APIs

From Videos to Spreadsheets

"The secret to creativity is knowing how to hide your sources.

Albert Einstein

quotes...

“'Google Data APIs Protocol' is a horrible name. You can tell that ex-Microsoft employees had a hand in this effort. :)”

GData for the Enterprise

Google Apps for your DomainGData APIs for Calendar, Spreadsheet, Document ListGoogle Apps APIs• User Provisioning Gdata: CRUD on users and lists• Reporting: post XML, receive CSV• SSO: SAML

SAML for Google Apps for Your Domain

Google Gears: Offline capabilities

Offline• Local Server: cache for HTML, js, css• Local SQLite Database: for application data

WorkerPool: like processes for javascript• More responsive applications

Google Web ToolkitWhat, Why, and How

Joel WebberGoogle, Inc.

What is Google Web Toolkit (GWT)?

What is GWT?• A set of tools for building AJAX apps in the Java language• Open Source (Apache 2.0 license)

What makes GWT interesting?• Write, run, test, and debug everything in Java, both client-side UI code

and server-side business logic

Isn’t that called an applet?• No JVM required• GWT converts your working Java source into pure JavaScript

GWT is a compiler?• GWT’s Java-to-JavaScript compiler is a big part of it, but there’s really

a lot more to the story than that…

Code Sample – Hello, AJAX

public class Hello implements EntryPoint {

public void onModuleLoad() {Button b = new Button("Click me", new ClickListener() {public void onClick(Widget sender) {Window.alert("Hello, AJAX");}});

RootPanel.get().add(b);}

}

Without further ado…

GWT Summary

Ajax is a lot of work… Make sure to build a code base you're glad to ownLots of rewards, lots of risksLeverage is needed to use Ajax well with minimum riskPhD in browser quirks is no longer an Ajax prereq Turn Ajax hacking into software engineeringWe will share our best work and ideas with you, and we hope you will return the favor

Much more to come… see you online!

API Lessons

All Services can benefit from an API: “Innovation happens elsewhere”Solve big problems for developersAll APIs should be self serviceNo ideology for technology choices: pragmatism winsListen to developers, Participate in the conversationOpen Source, Open Standards better than closed PlatformsCode speaks better than SlidewareGet started today at http://code.google.com/

Conclusion

Many bridges, using different technologies• No new SOAP API planned• REST for data and message APIs: Gdata• Ajax to surface customizable controls and enable mashups• Google Web Toolkit to build your own Ajax applications easily• Gears for offline support• Google App Engine for easy scalability• OpenSocial for the social enterprise

Exposing many Google services for Enterprises… and more to come: give it a try!
