Shift of Web

• From Showing Document to Working Environment.

• From Interlinked Document to Interactive Application.

• From Stateless Connection to Stateful Session Context.

• From Restricted Client Access to Utilize Local Computing Resource.

RIA Characteristics

• Client-Centric Application

• Rich and Responsive User Experience

• Client Computing Resource Utilization

• Stateful Connection

RIA User Acceptance

• The Early Adaptor Phase (2004 – 2008) • The Early Majority Phase (2009 – 2012)

By Gartner Dec. 2008, MarketScope for Ajax Technology and RIA Platform

RIA Description Language (RDL)

RIA Component Model (RCM)

RIA Platform Architecture (RPA)

Scope of Effort cont’d

• RIA Platform Architecture (RPA)

– Next generation web application execution

platform

– Interactive User Interface

– Just-in-time Deployment

Scope of Effort cont’d

• RIA Component Model (RCM)– Interoperable Heterogeneous Component– Basic Component Types– Interface Description– Event Flow and Handling– Repository and Deployment

Scope of Effort cont’d

• RIA Description Language (RDL)– Language Specification of RIA– Abstract Syntax of Structural Part • XML• Structure of Application

– Semantic Property of Behavior Part• ECMAScript • Objects, Functions, Events Handling,

Orchestration

Expected Deliveries

• RFI Draft– TC Meeting at Dec. 2009
