Metadata and data should be discoverable by both humans and machines.

To be Findable any data object should be uniquely and persistently identifiable:

  • The same data object should be re-findable at any point in time, thus data objects should be persistent, with emphasis on their metadata.

  • A data object should minimally contain basic machine actionable metadata that allows it to be distinguished from other data objects.

  • Identifiers for any concept used in data objects should therefore be unique and persistent.

This chapter is dedicated to the identifiers, standards, and services, and other resources necessary to enable and improve data discoverability by machines.
