Changes from the DCAT-AP-NL 1.1 standard¶
The changes from DCAT-AP-NL 1.1 to DCAT-AP-DONL 1.1 are listed below.
New properties¶
The following properties have been introduced
- Dataset:datasetStatus
- This recommended property defines in which part of a lifecycle a dataset exists. A dataset can be available, planned unavailable or being researched. Use Dataset:datePlanned to indicate when a dataset is expected to receive the datasetStatus available.
- Dataset:datePlanned
- This optional property defines the planned date at which this dataset becomes available. It is closely related to the datasetStatus planned, unavailable and being researched.
- Dataset:license
- This new, mandatory, property was introduced for the Dataset class. It allows a license to apply to a dataset, rather than a Distribution, which already had the license property.
- Dataset:metadataLanguage
- This new mandatory property forces providers to clarify which language is used in the metadata of a Dataset.
- Distribution:metadataLanguage
- This new mandatory property forces providers to clarify which language is used in the metadata of a Distribution.
Changed properties¶
The following properties have been modified
- Dataset:title
- The cardinality has been changed from 1..n to 1..1. Data.Overheid.nl demands that metadata is provided in only one language, therefore there is no longer any need to support multiple titles for one dataset.
- Dataset:description
- The cardinality has been changed from 1..n to 1..1. Data.Overheid.nl demands that metadata is provided in only one language, therefore there is no longer any need to support multiple descriptions for one dataset.
- Dataset:theme
- This property was changed from Recommended to Mandatory. Data.Overheid.nl requires at least one theme to properly categorize datasets. Because of this, its cardinality is changed from 0..n to 1..n.
- Dataset:authority
- This property was changed from Recommended to Mandatory. It must always be clear who owns the dataset, therefore this property needs to be mandatory. Because of this, its cardinality is changed from 0..1 to 1..1.
- Dataset:publisher
- This property was changed from Recommended to Mandatory. It must always be clear who published the dataset, therefore this property needs to be mandatory. Because of this, its cardinality is changed from 0..1 to 1..1.
- Dataset:contactPoint
- This property was changed from Recommended to Mandatory. A published dataset needs to have a contactPoint so that questions and/or comments regarding a dataset have a place to go. Because of this, its cardinality is changed from 0..n to 1..1.
- Dataset:conformsTo
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata. Furthermore, its range was narrowed to xsd:anyURI. Data.Overheid.nl prefers resolvable URIs from a linked data perspective.
- Dataset:alternativeIdentifier
- This property was changed from Optional to Recommended. The alternativeIdentifier is important in the quest to minimise duplicate datasets. As such this property now has a higher classification to signify this.
- Dataset:relatedResource
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata. Furthermore, its range was narrowed to xsd:anyURI. Data.Overheid.nl prefers resolvable URIs from a linked data perspective.
- Dataset:source
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata. Furthermore, its range was narrowed to xsd:anyURI. Data.Overheid.nl prefers resolvable URIs from a linked data perspective.
- Dataset:hasVersion
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata. Furthermore, its range was narrowed to xsd:anyURI. Data.Overheid.nl prefers resolvable URIs from a linked data perspective.
- Dataset:isVersionOf
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata. Furthermore, its range was narrowed to xsd:anyURI. Data.Overheid.nl prefers resolvable URIs from a linked data perspective.
- Dataset:releaseDate
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Dataset:version
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Dataset:version_notes
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a dataset as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Distribution:license
- This property was changed from Recommended to Mandatory. Data.Overheid.nl requires that all distributions have a license property. It must always be clear what license applies to a distribution. Because of this, its cardinality is changed from 0..1 to 1..1.
- Distribution:title
- The cardinality has been changed from 1..n to 1..1. Data.Overheid.nl demands that metadata is provided in only one language, therefore there is no longer any need to support multiple titles for one distribution.
- Distribution:description
- The cardinality has been changed from 1..n to 1..1. Data.Overheid.nl demands that metadata is provided in only one language, therefore there is no longer any need to support multiple titles for one distribution.
- Distribution:format
- This property was changed from Recommended to Mandatory. A Distribution always has a format, as such, it should be provided. Because of this, its cardinality is changed from 0..1 to 1..1.
- Distribution:byteSize
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a distributions as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Distribution:downloadURL
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a distributions as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Distribution:mediaType
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a distributions as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Distribution:releaseDate
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a distributions as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Distribution:rights
- This property was changed from optional to Mandatory. Rights always apply to Distributions, therefore providers must dictate which rights apply to the Distribution. Because of this, its cardinality is changed from 0..1 to 1..1.
- Distribution:status
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a distributions as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Distribution:modificationDate
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a distributions as possible. This is purely a semantic change to inspire providers to provide more metadata.
- Distribution:linkedSchemas
- This property was changed from Optional to Recommended. Data.Overheid.nl wants as much metadata about a distributions as possible. Furthermore its range has been narrowed to only allow valid URIs. Data.Overheid.nl prefers resolvable URIs from a linked data perspective.
