The following are definitions for each of the concepts and relationships shown above.    (3YWE)

Taxonomy    (3YWF)
A collection of controlled vocabulary terms organized into a hierarchical structure. Taxonomies provide a means for categorizing or classifying information within a reasonably well-defined associative structure, in which each term in a Taxonomy is in one or more parent/child (broader/narrower) relationships to other terms in the Taxonomy. A common example of a Taxonomy is the hierarchical structure used to classify living things within the biological sciences from Carols Linnaeus, as shown in Figure 6 3:    (3YWG)

Structured Data Resource    (3YWM)
See the Data Description chapter.    (3YWN)
Topic    (3YWO)
A category within a Taxonomy. A Topic is the central concept for applying context to data. For example, an agency may have a Taxonomy that represents their organizational structure. In such a Taxonomy, each role in the organizational structure (e.g. CIO) represents a Topic. Topic is often synonymous with “node”.    (3YWP)
Digital Data Resource    (3YWW)
See the Data Description chapter.    (3YWX)
Query Point    (3YWY)
See the Data Sharing chapter.    (3YWZ)
Exchange Package    (3YX0)
See the Data Sharing chapter.    (3YX1)
Relationship    (3YX2)
Describes the relationship [31] between two Topics.    (3YX3)
Data Asset    (3YX7)
A managed container for data. In many cases, this will be a relational database; however, a Data Asset may also be a Web site, a document repository, directory or data service.    (3YX8)
Data Steward    (3YXC)
A person responsible for managing a Data Asset.    (3YXD)
Other FEA Reference Model    (3YXG)
This concept represents the four other FEA reference models – the Business Reference Model (BRM), the Service Component Reference Model (SRM), the Technical Reference Model (TRM), and the Performance Reference Model (PRM). Its purpose is to provide a linkage to these other reference models, which are themselves Taxonomies. These are depicted as a special kind of Taxonomy due to their importance in overall classification of information.    (3YXH)

The table below provides attributes that are associated with each concept in the Data Context section of the DRM abstract model.    (3YXK)

add table    (3YXL)

[30] Because a Taxonomy is represented as a Structured Data Resource, and a Data Asset provides management context for a Digital Data Resource, it follows that a Taxonomy may be stored and managed within a Data Asset.    (3YXM)

[31] It should be noted that the term “relationship” is used in two ways here. The concept named “Relationship” participates in relationships with other concepts in the abstract model, and also defines the relationship between topics when it is applied to a specific scenario.    (3YXN)
