ClassificationScheme

All Superinterfaces:

ExtensibleObject, RegistryEntry, RegistryObject, Versionable
```
public interface ClassificationScheme
extends RegistryEntry
```
A ClassificationScheme instance represents a taxonomy that may be used to classify or categorize RegistryObject instances. A very common example of a classification scheme in science is the Classification of living things where living things are categorized in under a tree like structure. Another example is the Dewey Decimal system used in libraries to categorize books and other publications. A common example in eBusiness is that of North American Industry Classification System (NAICS), which is a classification scheme used to classify businesses and services by the industry to which they belong.
Figure 1 shows how a ClassificationScheme is used by a Classification to classify a RegistryObject.

- Field Detail
  - VALUE_TYPE_UNIQUE
```
static final int VALUE_TYPE_UNIQUE
```
    Each taxonomy value in ClassificationScheme is unique.
    
    See Also:
    
    Constant Field Values
  - VALUE_TYPE_EMBEDDED_PATH
```
static final int VALUE_TYPE_EMBEDDED_PATH
```
    Each taxonomy value in ClassificationScheme embeds the full path from scheme to that Concept. This also implies that each taxonomy value is unique.
    
    See Also:
    
    Constant Field Values
  - VALUE_TYPE_NON_UNIQUE
```
static final int VALUE_TYPE_NON_UNIQUE
```
    Taxonomy values in ClassificationScheme may be repeated within the same scheme. However, two Concepts that have the same parent cannot have the same value.
