本論文建立「Web 2.0後設架構分析框架」，可用於開發Web 2.0應用系統的結構化使用個案分析；首先從文獻歸納Web 2.0核心概念，再據之發展為分析框架。此框架包含兩部分，分別為「Web 2.0後設模型」以及兩階段的分析流程：第一階段以Web 2.0後設模型與系統需求產生出「Web 2.0實例模型」，第二階段加入非功能性需求分析，將實例模型轉換為UML使用個案。本論文使用四層之後設資料架構呈現此分析框架，並以股票交易型基金（ETF）之行銷與討論平台為例示範。 / This paper had proposed the “Web 2.0 meta-architecture analysis framework”, a structured use case analysis for Web 2.0 application systems: We first defined Web 2.0 core concepts and develop the analysis framework. The framework includes two parts: the “Web 2.0 meta-model” and a two-step analysis process. In the first step, the process generates “Web 2.0 instance-models” from the Web 2.0 meta-model and system requirements, which can be transformed into UML use cases along with non-functional requirements analysis in the second step. This paper presented this framework under four-layered meta-data architecture, and demonstrated the framework by using the case of ETF marketing and discussion platform.
