Storing resolution for raster data sources is very normalized in ISO 19115. In metacatalog, this does only apply to one kind of data source: 'raster'. Therefore we should rather introduce another lookup table for models.DataSource, that can store the scale triplet, consisting of extent, support and resolution, where each of them can be stored in a temporal and spatial scale.
One pathway might be to implement EX_Extent in a simplified version, as we need this one anyway for MD_Identification.
We could omit the verticalExtent for now and only work with BBOX, polygon and temporal scales.
