Hi, we want to ingest DataHub with custom metadata besides table metadata. In our use case, we have several tables containing lists of curves (ids of time series) and their description. We want to re-use DataHub features so that users can browse/search this custom metadata next to the regular table exports. Is it possible with DataHub?

take a look at custom properties https://datahubproject.io/docs/api/tutorials/custom-properties/#why-would-you-use-custom-properties-on-datasets you can search by custom properties

Hello, I don't think this suits our needs. I would like to have something like dataset entity, but having only tabs

and

Properties

for example. Then I would have urn

urn:li:my_entity:...

.
