
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
 Submission to www.programmableweb.com

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+ MASHUP
PROJECT
© 2011 IBM Corporation
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.”

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
© 2011 IBM Corporation
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 Parsers
XML/Java
Parsers help with validation, wellformedness checking, building a DOM,
notifying the application of errors
Two API Standards: DOM and SAX
Xerces2
Data Binding APIs
