What is Metadata:
metadata would be a machine understandable set of standards for describing data. This would enable Web functions like ratings and comparison shopping. Music retailers, for example, could create a standard set of HTTP queries for searching all music databases on the Web.The World Wide Web Consortium heads up several metadata efforts, such as the PICS project for labeling content and the Digital Signature Initiative.
Chinese definition:
"Meta Data" 指的是描述資料本身特性的資料，在全球資訊網上，它指的是讓機器看得懂的、描述資訊內容的所有相關資訊，例如描述資訊的所有權、著作權、流通權、隱私維護政策等，這可以幫助上網者更方便使用資訊。由於網路上對於這些相關資訊的需求愈來愈大，我們正在設計各種方法，將電腦能夠了解、辨認的資訊放上網路。目前以ＨＴＭＬ編寫的網頁，基本上是為了讓人類閱讀而設計的。將來，有一部份的網頁將會以所謂「資源描述結構 (Resource Description Framework,RDF)」寫成，由電腦軟體負責閱讀，幫助人類組織所有的資料。〞
