Express obsoleteness of datasets in Schema.org metadata representation

[ga-schneider]

• Observation: Some datasets have become obsolete due to different reasons. This isn’t reflected in the Schema.org metadata but is an important information, e.g. when displaying datasets in FAIRagros search hub.
  • Example: https://maps.bonares.de/mapapps/resources/apps/bonares/index.html?lang=en&mid=05dda4f7-17f9-4b57-bf1d-21a51725eada
• Improvement idea: Add information on the status of a dataset via https://schema.org/creativeWorkStatus.
  • When providing the status as a https://schema.org/Text, terms such as "obsolete" or "deprecated" or "superseded" could be used
  • When providing the status as a https://schema.org/DefinedTerm, a standardized terminology could be used, increasing the machine readability of the information. An example is the EU Dataset status controlled vocabulary but there are other possibilities.
  • https://schema.org/name should include the string for the dataset status (e.g. "deprecated")
  • https://schema.org/inDefinedTermSet a link to the chosen controlled vocabulary itself
  • https://schema.org/termCode the unique identifier of the dataset status in the controlled vocabulary
  • https://schema.org/url a resolvable link to the dataset status term
• Benefits: Clear and machine readable information on the dataset status usable by the FAIRagro Search Hub, helping users in identifying accessible datasets more easily
