2Web 2.0 and RIAs


• User-driven adoption

• Value on demand• Low cost of entry• Public infrastructure• Tight feedback loop

between providers and consumers

Software as aSERVICE

Service, not software

COMMUNITYmechanisms • Recommendations

• Social networking features

• Tagging• User comments• Community rights

management

Users add value

Web 2.0 VisionThree different software patterns for a new user experience

SIMPLEuser interface

and dataservices

• Responsive UIs (AJAX)• Feeds (Atom, RSS)• Simple extensions• Mashups (REST APIs)

Easy to use, easy to remix

Simple interfaces promise to increase adoption and help spur situational applications within the enterprise.

5Web 2.0 and RIAs


Rich Internet Applications

Rich Internet applications (RIAs):

– They are web applications that have the features and functionality of traditional desktop applications;

– They run in a web browser, and do not require software installation.

The “Rich” term is the real news of Web 2.0: – a “Rich Internet Application” is capable of delivering

a rich experience to the user.

– It is more connected, more alive, more interactive, and more responsive.

Rich Internet Application: Advantages and disadvantages

DisadvantagesAdvantages

If network is not available, we can’t use RIAs (but, honestly, is it a real problem?) Security of data is critical (but last technologies and deeply tested authentication mechanisms can help us)

All the PROs of Web Applications:They are easly upgradable because once a new relase is online, all users will use that relase, and the old one is no longer available.They are distribuited and reachable everywhere...

People is connected: RIAs are built on a network that connects us all the Internet. RIAs are Alive: That emotional response can help to improve our overall satisfaction with the software. RIAs should feel alive. People can interact: interaction is how we transmit and receive information. The richness of an experience is heavily dependent on this interaction made possible by our senses, and RIAs facilitate physical, audible, and visual interaction. Responsive: responses are quick due to Real-time streaming, high performance client side virtual machines, and local caching; mechanisms that are becoming in integral part of RIAs.

RIAs Offering: Technologies

Syndication formats and protocols

– RSS, Atom, Atom Publishing, CDF, GData

Why:

Saves the trouble of visiting each blog/wiki/site/podcast one at a time

Subscription model allows for more efficient content consumption

9Web 2.0 and RIAs



Lightweight integration methods

– “REST” style APIs

– Use from any HTTP-enabled application

– Web Services (SOAP, UDDI, WSDL)

A RESTful Web service is formed like a sentence:

Verb = HTTP Action (GET, POST, PUT, DELETE)

Noun = the URI of the Service (the document)

Adjective = MIME type of the resulting document

RIAs and SOA (1/2)

An information system implemented using both RIAs and SOA has a lot of advantages:

– Loosely coupled applications can be reused easly, and the maintenance is less expensive: upgrading a component, we will upgrade all the applications using that component

– Developing new applications is faster and easier: take components, combine them and the new application is ready to be used.

– Thanks to “Rich Internet Application” we can deliver a rich experience to the user (connected, alive, interactive and responsive).

Conclusions

Collaboration infrastructure is the key

Community enablement empowers the infrastructure

Social software is the glue that binds it all
