== Abstract
* 背景/動機：
** 以往，詮釋資料(metadata)只是資料庫與資料倉儲世界的次等公民；它主要的目的在於定義資料。\\ <fs 50%>In the past, metadata has always been a second-class citizen in the world of databases and data warehouses. Its main purpose has been to define the data. </fs>
** 然而，現今在資料倉儲與軟體儲存社群中，詮釋資料的重要性已經被顯著的提升了。組織需要利用詮釋資料整合不同的工具、資料與變革管理。\\ <fs 50%>However, the current emphasis on metadata in the data warehouse and software repository communities has elevated it to a new prominence. The organization now needs metadata for tool integration, data integration and change management.</fs>
* 假定：(N/A)
* 方法：(N/A)
* 資料：
** 本文從概念與管理的觀點，描述詮釋資料演變的過程。\\ <fs 50%>The paper presents a chronological account of this evolution—both from conceptual and management perspectives.</fs>
* 發現：
** 在現代，為了工具與資料整合的目的，人們利用儲存庫概念(repository concepts)來管理詮釋資料。\\ <fs 50%>Repository concepts are currently being used to manage metadata for tool integration and data integration. </fs>
** 在演變的最後階段，我們提出"詮釋資料倉儲"的概念。一個真實生活資料倉儲的計畫 TAMUS Information Portal (TIP) 可以隨著時間演變，描繪資料倉儲所需的詮釋資料類型。\\ <fs 50%>As a final chapter in this evolution process, we point out the need of a concept called “metadata warehouse.” A real-life data warehouse project called TAMUS Information Portal (TIP) is used to describe the types of metadata needed in a data warehouse and the changes that the metadata go through. </fs>
** 我們建議設計一個能儲存詮釋資料並管理其變動的詮釋資料倉儲。並建議數種發展詮釋資料倉儲的架構。<fs 50%>We propose that the metadata warehouse needs to be designed to store the metadata and manage its changes. We propose several architectures that can be used to develop a metadata warehouse.</fs>
