Dataset Facets are generally consisted of common facet that is used both in inputs and outputs of the OpenLineage event. There are facets that exist specifically for input or output datasets.

{
  ...
  "inputs": [{
    "namespace": "postgres://workshop-db:None",
    "name": "workshop.public.taxes-in",
    "facets": {
        # This is where the common dataset facets are located
    },
    "inputFacets": {
        # This is where the input dataset facets are located
    }
  }],  
  "outputs": [{
    "namespace": "postgres://workshop-db:None",
    "name": "workshop.public.taxes-out",
    "facets": {
        # This is where the common dataset facets are located
    },
    "outputFacets": {
        # This is where the output dataset facets are located
    }
  }],
  ...
}

In the above Example, Notice that there is a distinction of facets that are common for both input and output dataset, and input or output specific datasets. As for the common datasets, they all reside under the facets property. However, input or output specific facets are located either in inputFacets or outputFacets property.
