Classification Scheme

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In metadata a classification scheme is the descriptive information for an arrangement or division of objects into groups based on characteristics which the objects have in common. The ISO/IEC 11179 metadata registry standard uses classification schemes as a way to classify administered items, such as data elements, in a metadata registry. Metadata is loosely defined as data about data. Metadata is a concept that applies mainly to electronically archived or presented data and is used to describe the a) definition, b) structure and c) administration of data files with all contents in context to ease the use of the captured and archived data for further use. For example, a web page may include metadata specifying what language it's written in, what tools were used to create it, where to go for more on the subject and so on.
