Metax is fully compatible with DCAT 3 data-model, but has some minor variations allowed by the specification. This article will explain how DCAT is integrated into Metax V3 data-model.
Note
This comparison is comparing DCAT concepts to equivalent Metax database Models. V3 classes have Django application name in front of them.
