3.6.3 Discovery

As mentioned earlier (See Section 2. Definitions), metadata means data about data. They are used to document datasets and to help discover, describe and promote the existence of data. For more details, see Section 5. Metadata.

In a document about imagery management in aquatic science, Nozères (2011) proposes a set of core metadata for image and video files:

  • File name (highly recommended)
  • Creation Date (automatic, default)
  • Creator - Author (highly recommended)
  • Keywords (highly recommended)
  • Copyright Status (optional)
  • Title (optional)
  • Description - Légende (optional)
  • Location – sub-location (optional)
  • GPS (latitude, longitude, altitude)
