*** This action has been completed ***


The action defined alternative encoding rules (mainly for the purpose of viewing/analysis in mainstream GIS systems) for a number of selected application schemas and a template and procedure for proposing and endorsing additional encoding rules in the future.


The full action mandate is attached: MIWP-2017.2_Alternative_encodings_Action_mandate_endorsed.pdf


The outputs of the Action are made available on GitHub


Regular virtual meetings took place on Fridays from 10:00-11:30 CE(S)T

Background & context

The current data specification TGs define (complex) xml schemas based on GML as the default encoding for all INSPIRE spatial data themes. Many existing (web and desktop) applications and tools have difficulties in consuming and/or fully making use of data shared according to these schemas.


According to Art. 7 of the IRs on data interoperability, alternative encodings can be used as long as an encoding rule is publicly available that specifies schema conversion rules for all spatial object types and all attributes and association roles and the output data structure used. Such an encoding rule would need to include cross-cutting aspects (e.g. how to flatten recurring complex structures such as geographical names) as well as theme-specific aspects.

Organisational set-up

The work was carried out by a temporary MIG sub-group, coordinated by JRC and supported by a contractor. The call for participation is available here.
