A classification is a set of elements that is used to describe some characteristic. E.g. the classification {Granite, Latite, Tachylyte} could be used to describe the rock found at a specific location.

In Redbex classifications are used in property structures as values for properties of type classification or multi-select classification. Classification and multi-select classifications in property structures are important to standardize stored data and therefore also to provide a high quality of data.

Compared to simple textual information the usage of classifications - either in classification or multi-select classification property types - has the advantage that they standardize the vocabulary used to describe a specific characteristic.

From the example above we already see that a single classification that describes a single characteristic might not be enough. In different locations you will have different geological situation and therefore a different set of rock types. For ensuring a high quality of your data you therefore need different classifications to describe rock in different locations, i.e. the same characteristic is described with different classifications in different locations.

Redbex therefore pre-defines only the available classification types (i.e. the characteristic that shall be described). For each classification type the user can define any number of classifications including any number of classification elements. The classification type is therefore the container that can hold different classifications used to describe the same characteristic.

Classifications are bound to domains and only available within that domain and its sub-domains.

Example: Redbex defines a classification type named Rock that is used in more than one feature type to describe the geological situation at a specific location. Which types of rocks are used to describe the geological situation is usually defined by some national or international standard or perhaps also by a company standard or project standard. Therefore you can create any number of classifications for this classification type. In our example you would perhaps create one classification that consists of elements according to a German standard and another one according to an ISO-standard.
