DataHub

Hello :smiley:

I am trying to insert a tag using a Python emitter.
However, even if I modify the tags of `DatasetPropertiesClass`, the tag is not entered in the Datahub.
1. If I simply append string in tags , doesn’t it get input?
2. Do I need to put urn in tags?

I attach the code I used as a sample

```dataset_properties = DatasetPropertiesClass(description="This is Google Sample",
externalUrl="<https://www.google.com>", 
customProperties={},
tags = ['Active']
)

metadata_event = MetadataChangeProposalWrapper(
    entityType="dataset",
    changeType=ChangeTypeClass.UPSERT,
    entityUrn=builder.make_dataset_urn("google_sheet", "sample1"),
    aspectName="datasetProperties",
    aspect=dataset_properties,
)

emitter.emit(metadata_event)```

Hi. This one is a deprecated field. Can you add tags through this aspect? <https://github.com/linkedin/datahub/blob/master/metadata-models/src/main/pegasus/com/linkedin/common/GlobalTags.pdl> It is a common aspect across all entities

<@U02TZLT9S0Y>: you can find code examples and descriptions here -&gt; <https://datahubproject.io/docs/generated/metamodel/entities/dataset#tags-and-glossary-terms>

I checked what you shared! Thank you :man-bowing:
I confirmed that you shared how to write a Global Tag.

I tried to add tags to a specific dataset using python emitter.
The way I tried was to set Tags in DatasetPropertiesClass . It is not displayed on the Datahub.

Yeah so the tags field in DatasetProperties is deprecated and is not used anywhere

it shows tags as just plain strings without much metadata about the tag like description

so we moved to a separate GlobalTags aspect which can be applied to all entities

that specifies the list of tag urns to attach to each entity

That’s different from the DatasetPropertiesClass tag I was thinking!
thank you. Let’s try using global fields.
