DCAT-AP CH

La norme suisse en matière de métadonnées

DCAT-AP CH, le profil d’application suisse du vocabulaire de catalogage de données (Data Catalog Vocabulary, DCAT) pour les portails de données, se base sur le profil d’application international DCAT-AP standard. Il est implémenté sur opendata.swiss.

Les métadonnées de jeux de données moissonnées par opendata.swiss ou importées sur la plateforme par téléchargement XML doivent respecter la norme DCAT-AP CH. Les exigences minimales auxquelles vos métadonnées doivent répondre (mandatory, conditional) sont décrites ci-dessous, de même que les champs facultatifs qu’opendata.swiss prend en charge (optional).

Les normes DCAT-AP et DCAT-AP CH sont en constant développement. Il se peut par conséquent qu’elles diffèrent par moment de la norme implémentée sur opendata.swiss. Si c’est le cas, n’hésitez pas à nous contacter.

Si les métadonnées de vos jeux de données vont au-delà de la norme implémentée sur opendata.swiss, elles ne seront pas prises en compte et ne s’afficheront pas chez nous.

Cette documentation n’est pour l’heure disponible qu’en anglais.

RDF-File Structure & Example

Your data catalog must follow the DCAT-AP CH standard. It consists of the following 4 Classes:

• the catalog

• the publishers

• the datasets

• the distributions

These classes relate to each other as described below. All examples will be provided in both turtle and rdf/xml. rdf/xml is used for the actual import of the data. You can use a converter to convert between these two formats: https://www.easyrdf.org/converter

It is important to provide URIs for each of the classes in your catalog.

Data Catalog in Turtle

Here you can see how every class in the catalog has a URI

@prefix dcat: <http://www.w3.org/ns/dcat#> .
@prefix dct: <http://purl.org/dc/terms/> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .

<https://tierstatistik.identitas.ch/data/fig-cattle-pyr.csv>
  a dcat:Dataset ;
  dcat:distribution <https://tierstatistik.identitas.ch/de/fig-cattle-pyr.html> ;
  dct:publisher <https://tierstatistik.identitas.ch> .

<https://tierstatistik.identitas.ch/de/fig-cattle-pyr.html>
  a dcat:Distribution .

Data Catalog in RDF

In RDF the URIs are stored in the about attribute

<?xml version="1.0" encoding="utf-8" ?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
         xmlns:dcat="http://www.w3.org/ns/dcat#"
         xmlns:dct="http://purl.org/dc/terms/"
         xmlns:foaf="http://xmlns.com/foaf/0.1/">

  <dcat:Dataset rdf:about="https://tierstatistik.identitas.ch/data/fig-cattle-pyr.csv">
    <dcat:distribution>
      <dcat:Distribution rdf:about="https://tierstatistik.identitas.ch/de/fig-cattle-pyr.html">
        </dcat:Distribution>
      </dcat:distribution>
  </dcat:Dataset>

</rdf:RDF>

The example catalogs above show the classes without any further properties. Here you can find an overview of all possible properties and which of these you must provide.

• mandatory means you MUST provide them

• conditional means you must provide them under certain conditions

• optional means you may provide them

Example for Download

Have a look at the following file for a quickstart: full dataset example

Namespaces

All classes and properties have definitions that are accessible with a URI. Usually these URIs are provided in the header of the data catalog and receive an alias there, so that they can be easily referenced in the rest of the catalog: A dcat:Dataset really means http://www.w3.org/ns/dcat#Dataset. To avoid having to write that throughout the document, a namespace is defined by @prefix dcat: <http://www.w3.org/ns/dcat#> . in turtle or xmlns:dcat="http://www.w3.org/ns/dcat#" in RDF.

These are the namespaces that are used in DCAT-AP CH:

Internationalisation

The DCAT-AP CH Standard allows/supports that text elements of datasets and their distributions are translated in the following four languages:

• French (fr)

• German (de)

• Italian (it)

• English (en)

Examples are provided for how to translate those elements for all relevant properties.

Overview

Below you find a list of classes that you need to implement in your catalog. Translatable elements are marked as such under usage notes.

Description

The terms of use indicates for what purpose and in what context the data of a distribution can be used: for commercial or for non commercial purposes. Does it need to be referenced, when it is used? Must permission be obtained for commercial use. These conditions are included in the terms of use statements. See the list below for the exact values.

Usage Notes

Terms of use are no longer referenced under dct:rights, but under dct:license.

Exception: If other licenses, such as CC-licenses, are used for the dataset besides the terms of use, they must be referenced under dct:rights. Only the terms of use from the list below are displayed on opendata.swiss. If other licenses are included, they should be referenced under dct:rights to pass on to the portal data.europa.eu.

Terms of use values to be used: DCAT-AP CH license vocabulary

Description

Minimum time period resolvable in the dataset distribution.

Usage Notes

If the dataset is a time-series this should correspond to the spacing of the items in the series. For other kinds of dataset, this property will usually indicate the smallest time difference between items in the dataset.

Usage Notes

Alternative temporal resolutions might be provided in different dataset distributions.

Description

This property refers to a data service that gives access to the distribution of the Dataset.

Usage Notes

The class dcat:DataService is currently not implemented in opendata.swiss and will therefore not be imported. However, if the property dcat:accessService exists in the catalogue, it will be imported and forwarded to data.europa.eu.
