DataFeed

A Schema.org Type
A single feed providing structured information about one or more entities or topics.
PropertyExpected TypeDescription
Properties from DataFeed
dataFeedElement DataFeedItem  or
Text  or
Thing
An item within a data feed. Data feeds may have many elements.
Properties from Dataset
distribution DataDownload A downloadable form of this dataset, at a specific location, in a specific format. This property can be repeated if different variations are available. There is no expectation that different downloadable distributions must contain exactly equivalent information (see also DCAT on this point). Different distributions might include or exclude different subsets of the entire dataset, for example.
includedInDataCatalog DataCatalog A data catalog which contains this dataset. Supersedes catalog, includedDataCatalog.
Inverse property: dataset
issn Text The International Standard Serial Number (ISSN) that identifies this serial publication. You can repeat this property to identify different formats of, or the linking ISSN (ISSN-L) for, this serial publication.
measurementMethod DefinedTerm  or
MeasurementMethodEnum  or
Text  or
URL
A subproperty of measurementTechnique that can be used for specifying specific methods, in particular via MeasurementMethodEnum.
measurementTechnique DefinedTerm  or
MeasurementMethodEnum  or
Text  or
URL
A technique, method or technology used in an Observation, StatisticalVariable or Dataset (or DataDownload, DataCatalog), corresponding to the method used for measuring the corresponding variable(s) (for datasets, described using variableMeasured; for Observation, a 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 PropertyValue for each variableMeasured and attach the corresponding measurementTechnique. The value can also be from an enumeration, organized as a MeasurementMethodEnum.
variableMeasured Property  or
PropertyValue  or
StatisticalVariable  or
Text
The variableMeasured property can indicate (repeated as necessary) the variables that are measured in some dataset, either described as text or as pairs of identifier and description using PropertyValue, or more explicitly as a StatisticalVariable.
Properties from CreativeWork
about Thing The subject matter of an object.
Inverse property: subjectOf
abstract Text An abstract is a short description that summarizes a CreativeWork.
accessMode Text The human sensory perceptual system or cognitive faculty through which a person may process or perceive the intellectual content of a resource, not including any adaptations of the content (e.g., text alternatives for images). Values should be drawn from the approved vocabulary.
accessModeSufficient ItemList A list of single or combined access modes that are sufficient to understand all the intellectual content of a resource, including any adaptations. Values should be drawn from the approved vocabulary.
accessibilityAPI Text Indicates that the resource is compatible with the referenced accessibility API. Values should be drawn from the approved vocabulary.
accessibilityControl Text Identifies input methods that are sufficient to fully control the described resource. Values should be drawn from the approved vocabulary.
accessibilityFeature Text Content features of the resource, such as accessible media, alternatives and supported enhancements for accessibility. Values should be drawn from the approved vocabulary.
accessibilityHazard Text A characteristic of the described resource that is physiologically dangerous to some users. Related to WCAG 2.0 guideline 2.3. Values should be drawn from the approved vocabulary.
accessibilitySummary Text A human-readable summary of specific accessibility features or deficiencies, consistent with the other accessibility metadata but expressing subtleties such as "short descriptions are present but long descriptions will be needed for non-visual users" or "short descriptions are present and no long descriptions are needed".
accountablePerson Person Specifies the Person that is legally accountable for the CreativeWork.
acquireLicensePage CreativeWork  or
URL
Indicates a page documenting how licenses can be purchased or otherwise acquired, for the current item.
aggregateRating AggregateRating The overall rating, based on a collection of reviews or ratings, of the item.
alternativeHeadline Text A secondary title of the CreativeWork.
archivedAt URL  or
WebPage
Indicates a page or other link involved in archival of a CreativeWork. In the case of MediaReview, the items in a MediaReviewItem may often become inaccessible, but be archived by archival, journalistic, activist, or law enforcement organizations. In such cases, the referenced page may not directly publish the content.
assesses DefinedTerm  or
Text
The item being described is intended to assess the competency or learning outcome defined by the referenced term.
associatedMedia MediaObject A media object that encodes this CreativeWork. This property is a synonym for encoding.
audience Audience An intended audience, i.e. a group for whom something was created. Supersedes serviceAudience.
audio AudioObject  or
Clip  or
MusicRecording
An embedded audio object.
author Organization  or
Person
The author of this content or rating. Please note that author is special in that HTML 5 provides a special mechanism for indicating authorship via the rel tag. That is equivalent to this and may be used interchangeably.
award Text An award won by or for this item. Supersedes awards.
character Person Fictional person connected with a creative work.
