How to extend INSPIRE code lists

  • General

    The INSPIRE Community Forum is now part of the INSPIRE helpdesk system, based on GitHub (, so please start there any new discussions.

    The current platform will remain available in read only mode in its current form and URL address until 31/01/2021, then its content will be archived and then published in a different URL which will be announced when it becomes available.

The extensibility of a code list defines which additional values (other than those explicitly specified) are allowed as valid values of the code list:

a) code lists whose allowed values comprise only the values specified in the IR (;

b) code lists whose allowed values comprise the values specified in the IR and narrower values i.e. values that have a hierarchical relationship to a more general parent value (

c) code lists whose allowed values comprise the values specified in the IR and additional values at any level defined by data providers ( ;

d) code lists, whose allowed values comprise any values defined by data providers – empty code lists ( .

The Article 6(3) of the Implementing Rules requires that additional code lists values and their definitions are made available in a public register (this enables users of the data to look up the meaning of the additional values used in a data set, and also facilitates the re-use of additional values by other data providers).

How to set up registers for INSPIRE, including registers for extended INSPIRE code lists, is described in the Best Practices for registers and registries & Technical Guidelines for the INSPIRE register federation, more specifically in Annex C “Using extended code lists when sharing INSPIRE data”.
