Hi everyone!
Does anyone have experience with exporting a dataset's metadata from Datahub to a different data catalog?
Use cases:
A) Our org has to export certain open data sets to a CKAN based open data platform. Ideally I would like to generate the CKAN json metadata objects for registering the open datasets directly from datahub.
B) Our org has to register certain data sets with our owner (a governmental institution) which uses a different catalog vendor.
In both cases the metadata would be tagged with a certain attribute (business glossary term) and should be exported depending on that.
What is the recommended way to export this metadata? Should I grab this directly from the datahub database? Is it possible to use the graphql interface? Any other ideas?
Thanks! thankyou

you could query the dataset's metadata using graphql, but CKAN also requires a copy of the actual data to be uploaded into it right? (which Datahub doesnt store)

yes, CKAN requires a separate data upload that is handled somewhere else. But ideally I d like the metadata json to be generated automatically from the catalog. But I was wondering, if there any best practices for exporting from data hub.
