## X.500 Naming Concepts

Large amounts of information need to be organized in some way to make efficient retrieval possible and ensure that names are unique. Information in the DIB is organized into a hierarchical structure known as the Directory Information Tree (DIT). The structure and naming of the nodes in the DIT are specified by registration authorities for a standardized set of X.500 names and by implementers of the directory service (such as OSF) for implementation-specific names. The DIT hierarchy is described by a schema. Schemas are described in more detail in Schemas .

Although the X.500 standard does not mandate a specific schema, it does make general recommendations. For example, countries and organizations should be named close to the root of the DIT; people, applications, and devices should be named further down in the hierarchy. GDS supplies a default schema that complies with these recommendations.
