Abstract

The Data Value Vocabulary (DaVe) is an extensible core vocabulary that allows user to use custom data value dimensions and metrics to characterise data value in a specific context. This flexibility allows for the comprehensive modelling of data value. As a data value model, DaVe allows users to monitor data value as it occurs within a data exploitation or value creation process (data value chain)

Term Description

In this section, the classes and properties that provide a basis for the Data Value Vocabulary (DaVe) are described

Classes

This is the smallest unit of characterisation of data value. It is part of a larger group called Metric Group (See dave:MetricGroup). This concept represents metrics that are heuristics designed to fit a specific assessment situation. Metrics are provided as subclasses of this abstract class, which is not intended for direct usage.

In Range of:

dave:implementsMetric , dave:hasValueMetric
A metric group is the second level of characterisation of data value, and represents a group of metrics that are related to each other, e.g. by being a recognised set of independent proxies for a given data value dimension. Each Metric Group is a part of a larger group called dimension (See dave:Dimension). MetricGroups are provided as subclasses of this abstract class, which is not intended for direct usage.

dave:hasValueMetric

In Range of:

dave:hasValueGroup
This represents the highest level of the characterisation of data value. A Dimension contains a number of data value Metric Groups. Dimensions are provided as subclasses of this abstract class, which is not intended for direct usage.

Described by:

dave:hasValueGroup

In Range of:

dave:hasValueDimension

Subclass of:

qb:DataSet
Contains the measurement (quantification) of a data value metric for assessing a data resource or dataset, as well as details about the assessment execution.

Described by:

sdmx-dimension:timePeriod , dave:computedOn , dave:hasValue

In Range of:

dave:hasValueMeasurement

Subclass of:

qb:Observation
Describes a data value metric, including the context of use, the expected result, and the approach taken within the Metric to assess data value

In Range of:

dave:hasDescription
Identifies a specific framework or toolset that implements data value metrics

Described by:

dave:implementsMetric
Defines an aggregation of data value dimensions that characterise data value for a specific context of data use.

Described by:

dave:relevantToDataset , dave:hasValueDimension

Properties

Each metric will return a quantification of value. Since there will be different return types for different metrics, this property will link a metric with a value object, including boolean, double, literal, etc.

Domain of:

dave:ValueMeasurement

Has Cardinality:

1
This property provides a link between a metric, and any number of measurements for the implementation of this metric.

Domain of:

dave:Metric

Range of:

dave:ValueMeasurement
This property will link a metric with its relevant description.

Domain of:

dave:Metric

Range of:

dave:Description
This property will link a toolset to any metrics it implements.

Domain of:

dave:Toolset

Range of:

dave:Metric
This property will link a data metric group (dave:MetricGroup) to the related metrics (dave:Metric).

Domain of:

dave:MetricGroup

Range of:

dave:Metric
This property will link a Dimension (dave:Dimension) to data metric groups (dave:MetricGroup).

Domain of:

dave:Dimension

Range of:

dave:MetricGroup
This property will link a Data Value object (dave:DataValue) to any data value dimensions it contains.

Domain of:

dave:DataValue

Range of:

dave:Dimension
This property indicates the data resource or dataset that is being analysed using a Data Value metric.

Domain of:

dave:ValueMeasurement

Range of:

dcat:Dataset

Has Cardinality:

1
This property indicates the data resource or dataset that the data value metadata describes.

Domain of:

dave:DataValue

Range of:

dcat:Dataset
