Hi @<1523701087100473344:profile|SuccessfulKoala55> , thanks, and how can I get the "id" to use with update for the dataset folder case?

This would be the "project" property of the dataset (which you can also get with the APIClient)

To update tags on a dataset version (task), use:

from clearml.backend_api.session.client import APIClient
client = APIClient()
# update tags for a dataset folder
client.tasks.update(task="id", tags=["bar"])

Hi @<1570220858075516928:profile|SlipperySheep79> , you can use the APIClient to do that, like this:

from clearml.backend_api.session.client import APIClient
client = APIClient()
# update tags for a dataset folder
client.projects.update(project="id", tags=["foo"])
