| Abstract: | Metadata, commonly defined as "data about data" , is a structured information set that describes the content, quality, condition, availability and other characteristics of data. In order to make up the metadata standard for Engineering Chemistry Database ( ECDB) , the author analyze most of the current international metadata standards carefully. Our Standard not only focuses on Engineering Chemistry data sharing but also aims at solving the existed problems of the Engineering Chemistry Database. The metadata standard we established includes management, identification, contents, quality, and distribution of information or data. |
