1. RESTx: Rest for the rest of us
Ken Yagen
Silicon Valley Code Camp, October, 2010

2. Agenda
• The Programmable Web
• What is RESTx?
• Demo
• Building a simple component
• Roadmap
• Questions / More information

3. The Programmable Web
• Resources
• Must have a URI
• Addressability
– Name them using URIs
– Give them structure - http://www.restxdemo.org/resource/sales/2004/Q4
• Representations
– Resources support different representations (XML, JSON, HTML, SVG, …)
• Uniform Interface
– HTTP (GET, HEAD, PUT, DELETE, POST)
• Statelessness, Connectedness
• Building Blocks (HTTP, URI, XML, JSON)

5. What is RESTx?
• The simplest way to create RESTful web services
• Encourages and enables RESTful concepts
• Hides underlying implementation details
• RESTx resources are self documenting and discoverable
• RESTx is a server, not a framework
• Use Cases
• Create rich data services by integrating different data sources
• Customized resources from cloud services and internal databases
• Data Layer for JavaScript application
• Wrap legacy scripts into reusable components

8. Building a simple component
• Create Component
./restxctl component create MyTestComponent [ java | python | javascript ]
• Annotate It
@ComponentInfo(name = "SomeSampleComponent",
description = "One line description of the component",
doc = "Longer description text, possibly multi-line, goes here“)
• Implement service method
• Compile it (Java only)
./restxctl component compile
• Start Server
./restxctl start

• Pipelines
• Ruby, Groovy, PHP Support
• iBeans Support
• Version Control, Caching

10. Why RESTx?
• Publishing Data as RESTful resources
• Any piece of interesting data can be a resource
• Users can construct their own resources
• Resources are accessible from an web URL
• Self-documenting and browse-able APIs are powerful
• Accessible for less-skilled developers, different language skills
• Java, Python, JavaScript
• Makes it easier to develop web 2.0 and mobile apps that require
access to external resources
