Publication of a first version of the HeCo ontology

After a first work of the Carto4CH core team, we have stabilized a first version of the HeCo ontology (version 0.5).

This version will allow us to have a first support to exchange with the partners of the project.

The objective is that this ontology is questioned, tested, until it stabilizes to be used in the cartography.
