Something like
info.processed:
type: io.MemoryDataset
metadata:
kedro-viz:
layer: processing

But how is it done with custom datasets?
In kedro viz it's always displayed as MemoryDataset and it won't accept the layer name. 😕
But as soon as I switch
info:
type: workloadcalculation.datasets.pics_dataset.PICS_Dataset
filepath: "data/08_reporting/pics"
<<: *reporting_layer
to
info:
type: pandas.CSVDataset
filepath: "data/08_reporting/pics"
<<: *reporting_layer
it does work

08/12/2025, 3:10 PMYou can look at csv_dataset - https://docs.kedro.org/projects/kedro-datasets/en/kedro-datasets-8.0.0/api/kedro_datasets/pandas.CSVDataset/
for how metadata is assigned. Let me know if this helps
