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 6 © 2011 IBM Corporation

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 © 2011 IBM Corporation

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 © 2011 IBM Corporation

What is a Web service? W 3 C 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. ” © 2011 IBM Corporation

Service Oriented Architecture Roles Find Service Registry Publish Advertise service Discover service Service Provider

SOAP A W 3 C 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 © 2011 IBM Corporation

XML Parsers XML/Java Parsers help with validation, wellformedness checking, building a DOM, notifying the application of errors Two API Standards: DOM and SAX Xerces 2 Data Binding APIs © 2011 IBM Corporation
