Enum Class License

All Implemented Interfaces:

Serializable, Comparable<License>, Constable

public enum License
extends Enum<License>

Enumeration of the set of licenses GBIF supports for applying to a dataset. The license provides a standardised way to define appropriate uses of a dataset.
GBIF's recommended best practice is to use the most recent license version, which for CC-BY and CC-BY-NC is 4.0. This is in line with the recommendation from Creative Commons. The ordinal number in the Enum implicitly defines the level of restriction, see LicenseTest.
