In the abstract, the resulting structures are a crucial aspect of metadata, often represented as a hierarchical structure and accompanied by descriptive information of the classes or groups. Such a classification scheme is intended to be used for the classification of individual objects into the classes or groups, and the classes or groups are based on characteristics which the objects (members) have in common.

The following are examples of different kinds of classification schemes. This list is in approximate order from informal to more formal:
One example of a classification scheme for data elements is a representation term.
