|
*dcat:theme* est utilisé pour assurer l'indexation sémantique des données de la manière la plus homogène et la plus interopérable possible. Pour cela, il est préconisé d'utiliser cette propriété pour décrire le contexte d'observation dont sont issues les données décrites dans le dataset, à savoir : la ou les variables mesurées, l'objet d'étude ou objet d'intérêt, la plateforme utilisée ainsi que les capteurs. Pour instancier ces quatre groupes *dcat:theme*, nous recommandons de les décrire en utilisant leur URI correspondants. Pour cela, il est recommandé d'utiliser les URI des ressources terminologiques proposées par les thésaurus des pôles ou celles proposées dans la colonne vertébrale Data Terra.
|
|
|
|
|
|
|
|
> **Note** : (paragraphe à reformuler)
|
|
|
|
> Un élément clé des propriétés concernant les **dcat:Dataset** est le lien à construire entre les jeux de données et la colonne vertébrale terminologique Data Terra. Ces liens thématiques se matérialisent à partir de la propriété **dcat:theme**. Ces liens d'interopérabilité permettent une harmonisation entre les métadonnées des jeux de données qui présentent des éléments communs (les ponts entre les silos des pôles de données). C'est ainsi que le catalogue fédéré, en s'appuyant sur la colonne vertébrale terminologique Data Terra, est capable de faire remonter, par exemple, toutes les variables en relation avec les objets d'intérêt recherchés, et ceci indépendamment de la provenance (compartiment du système Terre) des jeux de données en question.
