In [[information science]] and [[ontology (information science)|ontology]], a '''classification scheme''' is thean productarrangement of arrangingclasses thingsor into kindsgroups of things (classes). orThe into ''groups''activity of classes;developing the thisschemes bears similarity to [[categorizationtaxonomy]], but with perhaps a more [[classification (general theory)|theoretical]] bent, as a single classification scheme can be applied over a wide [[semantic spectrum]] while taxonomies tend to be devoted to a single topic.

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 anthe arrangement or division[[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 [[ISO/IEC 11179]] metadata registry standard uses classification schemes as a way to classify administered items, such as [[data element]]s, in a [[metadata registry]].
