====== 2.3 Taxonomic Views ======
[[dido:public:ra:1.2_views:start|return to Architectural Views]]

A [[dido:public:ra:xapend:xapend.a_glossary:t:taxonomy|taxonomy]] is a way of organizing things into useful and convenient classes. Each [[dido:public:ra:xapend:xapend.a_glossary:c:class|class]] can then be treated as an abstraction of the individual elements. For example, **Dog** is a class of **Animal**. Once an individual [[dido:public:ra:xapend:xapend.a_glossary:e:entity|entity]] is classified as a **Dog**, generalizations can be made about what to expect from that individual entity. 

There can be many taxonomies that classify entities. In the above taxonomy, there is a class called **Dog**, however, the class can also be part of different taxonomies such as **role** where the dog can be classified as "pet" or "working" and within **working** it can be further classified as **''herding''**, **''guard''**, or **''tracking''**. 

For example, one taxonomic classification places an individual in the animal kingdom; however, another taxonomy classifies an individual according to their state of employment (working, retired, etc.). Each is valid; the only difference is perspective.

The DIDO RA employs the following taxonomies:
