Identification Scheme

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In metadata, an identification scheme is used to identify unique records in a set. If a data element is used to identify a record within a data set, the data element uses the Identifier representation term. An identification scheme should be contrasted with a classification scheme. Classification schemes are used to classify individual records into categories. Many records in a data set may be in a single category.
