Name Provided by Details
Conceptual Domain Aristotle Metadata Registry 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 Catalog Aristotle Dataset Registration Extensions A Data Catalog records a curated collection of data sets.
Data Element Aristotle Metadata Registry 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 Aristotle Metadata Registry 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 Aristotle Metadata Registry 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 Set Aristotle Dataset Registration Extensions A Data Set describes a record of data, including any location or time boundaries for the data, that has been captured and is available for use under a specific licence. A Data Set may be included in a Data Catalog, and can reference multiple Distributions that record different parts or formats of the data that are available to download.
Data Set Specification Aristotle Dataset Registration Extensions A Data Set Specification describes an agreement to collect an ideal standard of data. A Data Set Specification may reference other Data Set Specifications or Data Elements to describe the data that should be collected under the agreement.
Data Type Aristotle Metadata Registry A Data Type describes a way of storing a specific form of data within a system.
Distribution Aristotle Dataset Registration Extensions A Distribution describes the structure and format of a specific downloadable collection of data. Multiple Distributions that capture different parts of data or provide different formats for data may be grouped into a single Data Set.
Object Class Aristotle Metadata Registry 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 Aristotle Metadata Registry A Property is an attribute common to all members of a set of things defined by an Object Class.
Relation Aristotle Concept Links and Relations A Relation defines a relationship that can be used to link different metadata items within the registry. Each Relation can specify a number of roles that metadata can fill within the relationship.
Unit Of Measure Aristotle Metadata Registry 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 Aristotle Metadata Registry 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.
