Agenda

Introduction The IBM team Create Your Own Adventure Project Defined What is it there for you

Web 2.0 Application or Mashup Project

Questions?


IBM Project Team

Project Lead: Gergana Markova

Each team will have dedicated Lead Technical Mentor and Lead Project Mentor: TBD

Technical Mentors The Go-To experts for any technical questions and challenges

Project Mentors Project environment, scheduling Facilitation & collaboration Team dynamics

Other Open Source online resources and forums IBM Academic Initiative Student Forum IBM Developer Works resources IBM Smart Planet resources


Your Project, “Choose your own adventure”

General Project Technology / Requirements Open Source Web 2.0 Mashups Programming Language: Java ; Can use Ruby on Rails and other platforms Project Repository : Source forge . Net

Use its Wiki, forums to provide status; CVS to check code Defect Tracking (SF.net tracker, Bugzilla, etc…) Project Discussion Forum/Log of your choice (e.g., Wiki) Unit testing of your choice (e.g., JUnit) In the end, it’s your decision what to do!

Deliverables Mandatory

Your project in a public repository, fully documented Optional

An article that will be published on IBM DeveloperWorks detailing your experience

Agile Development

Globalization Awareness

Code Inspection Techniques

Research and resources evaluation

Concepts Emphasized Open Source Process

Global Community Involvement

Design Patterns

eXtreme Programming

User Experience


Why Open-source?

Standardization of the rail network enabled industrialized America and Europe

A connecting platform fueling growth, creating new business opportunities Connecting resources with factory efficiencies Connecting goods with markets Enabling new distribution models (Sears Roebuck)

Other technology platforms: electricity grid, national highway systems, ……..the internet

“Standards contribute more to economic growth than patents and licenses.”

"Economic benefits of standardization“, Technical University Dresden (TUD) and the Fraunhofer Institute for Systems and Innovations


Web 2.0+ MASHUPPROJECT


Mashup

A hybrid application that combines content from more than one source.

Very popular Web 2.0 idea

Mash-up (you can use a hyphen if you want)

The real power in Web services comes from combining

Web services are typically specialized, mashups are “situational”

Development without central authority


Web 2.0

Web 2.0: O’Reilly Media coined the term

Web 1.0 vs. 2.0

One-to-many vs. many-to-many publishing

Application gets better as publishers make it better vs. application gets better the more people use it

No AJAX vs. AJAX


What is a Web service?

W3C Web Services Architecture Group

“A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards.”


Service Oriented Architecture Roles

Service Requester

Service Registry

Service Provider

FindDiscover service

PublishAdvertise service

Bind/InvokeRequest service


SOAP

A W3C Specification

An XML format, typically holds information for a Web service method call, or a response

Programming language independent

SOAP expanded: Services-Oriented Access Protocol

Used to be Simple Object Access Protocol


WSDL

Web Services Description Language

A kind of IDL (Interface Definition Language)

An XML format to describe a Web service’s capabilities

Describes a service as a set of endpoints operating on messages


XML/Java XML Parsers

Parsers help with validation, well-formedness checking, building a DOM, notifying the application of errors

Two API Standards: DOM and SAX

Xerces2

Data Binding APIs


Suggested ApproachEnvironment setup

Service discovery

Your Mashup or Open Application Concept

Web service Providers


Real Mashup Exampleshttp://www.allapis.com/

Yahoo_Flickr_Weather_Maps.aspx

Allows users to search US cities/locations - provides users with information on the city requested

Weather Forecasts

Wikipedia geo Articles

Flickr photos

APIs used Flickr

GeoNames

Yahoo Geocoding

Yahoo Maps


Skills RequiredJava Programming, nothing fancy

Basic web service concepts: SOAP, WSDL

Basic web-application concepts: URLs, HTTP, JavaScript, server-side scripting (JSP, PHP, other)

Basic XML (syntax, parsing)

AJAX (would be nice)

CSS (optional)


Gain ExperienceJ2EE

Web services

SOAP

Axis

JAX-RPC

XML

Web UI

AJAX


Random Food for Thought

Build a small application and utilize an open source framework or library

Hibernate

Spring

How can _you_ make our Planet Smart?

Make a difference beyond this class
