|Conceptual Domain||A Conceptual Domain describes a set of ideas that can be recorded using codes when storing data. When linked to multiple Value Domains, a Conceptual Domain can be used to find similarities in different code sets.|
|Data Element||A Data Element is a precise way of defining how a piece of data is recorded for a specific set of objects, using reusable metadata components. Data Elements are composed of a Data Element Concept, which describes the meaning of the data, and a Value Domain which describes how the data is recorded.|
|Data Element Concept||A Data Element Concept defines an idea that could be recorded by data, without specifying how it would be stored or measured. Data Element Concepts are composed of an Object Class, which describes the thing of interest, and a Property that defines which attribute of the thing would be recorded. Data Element Concepts can be referenced by multiple different Data Elements that each specify the Value Domain used to record the data.|
|Data Element Derivation||A Data Element Derivation describes a standardised rule or equation that transforms a set of input Data Elements to produce a set of output Data Elements. application of a derivation rule to one or more input|
|Data Type||A Data Type describes a way of storing a specific form of data within a system.|
|Object Class||An Object Class defines a way of identifying or classifying a set of real objects, ideas or events that all share common measurable attributes.|
|Property||A Property is an attribute common to all members of a set of things defined by an Object Class.|
|Unit Of Measure||A Unit of Measure describes units (eg. metres, litres, seconds) which can be used to record a measurement. A Value Domain can link to a single Unit of Measure to describe the units used to measure the associated data which can be used when to finding or comparing similar data.|
|Value Domain||A Value Domain describes how to record the measurement of a particular type of data, either using a coded list of values or a description of the possible values. Value Domains can be linked to Data Elements that all share a common way of recording data, and its values can be linked to a Conceptual Domain to provide additional context.|
