NAME

SemanticWeb::Schema::DataCatalog - A collection of datasets.

VERSION

version v23.0.0

DESCRIPTION

A collection of datasets.

ATTRIBUTES

dataset

A dataset contained in this catalog.

A dataset should be one of the following types:

InstanceOf['SemanticWeb::Schema::Dataset']

_has_dataset

A predicate for the "dataset" attribute.

measurement_method

measurementMethod

A subproperty of [[measurementTechnique]] that can be used for specifying specific methods, in particular via SemanticWeb::Schema::MeasurementMethodEnum.

A measurement_method should be one of the following types:

InstanceOf['SemanticWeb::Schema::DefinedTerm']

InstanceOf['SemanticWeb::Schema::MeasurementMethodEnum']

Str

_has_measurement_method

A predicate for the "measurement_method" attribute.

measurement_technique

measurementTechnique

A technique, method or technology used in an SemanticWeb::Schema::Observation, SemanticWeb::Schema::StatisticalVariable or SemanticWeb::Schema::Dataset (or SemanticWeb::Schema::DataDownload, SemanticWeb::Schema::DataCatalog), corresponding to the method used for measuring the corresponding variable(s) (for datasets, described using [[variableMeasured]]; for SemanticWeb::Schema::Observation, a SemanticWeb::Schema::StatisticalVariable). Often but not necessarily each [[variableMeasured]] will have an explicit representation as (or mapping to) an property such as those defined in Schema.org, or other RDF vocabularies and "knowledge graphs". In that case the subproperty of [[variableMeasured]] called [[measuredProperty]] is applicable.

The [[measurementTechnique]] property helps when extra clarification is needed about how a [[measuredProperty]] was measured. This is oriented towards scientific and scholarly dataset publication but may have broader applicability; it is not intended as a full representation of measurement, but can often serve as a high level summary for dataset discovery.

For example, if [[variableMeasured]] is: molecule concentration, [[measurementTechnique]] could be: "mass spectrometry" or "nmr spectroscopy" or "colorimetry" or "immunofluorescence". If the [[variableMeasured]] is "depression rating", the [[measurementTechnique]] could be "Zung Scale" or "HAM-D" or "Beck Depression Inventory".

If there are several [[variableMeasured]] properties recorded for some given data object, use a SemanticWeb::Schema::PropertyValue for each [[variableMeasured]] and attach the corresponding [[measurementTechnique]]. The value can also be from an enumeration, organized as a SemanticWeb::Schema::MeasurementMetholdEnumeration.

A measurement_technique should be one of the following types:

InstanceOf['SemanticWeb::Schema::DefinedTerm']

InstanceOf['SemanticWeb::Schema::MeasurementMethodEnum']

Str

_has_measurement_technique

A predicate for the "measurement_technique" attribute.
