Classification scheme
From Wikipedia, the free encyclopedia
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.

[edit] Benefits of using classification schemes
Setting up one or more classification schemes for a collection of objects has many benefits. Some of these include:
- allows a user to quickly find an object in a large object collection
- makes it easier to detect duplicate objects
- conveys semantics (meaning) of an object that is not conveyed by the object name or definition
[edit] Examples of classification schemes
The following are examples of different classification schemes. This list is in approximate order from informal to more formal:
- keyword - a list of uncategorised words or phrases associated with an object
- thesaurus - a list of categorized words or phrases associated with an object
- taxonomy - a formal list of controlled words arranged from abstract to specific
- data model - an arrangement of words or phrases that have complex many-to-many relationships
- network (mathematics) - an arrangement of objects in a random graph
- ontology - an arrangement of objects in a directed acyclic graph with multiple inheritance
One example of a classification scheme for data elements is a representation term.
