### Method Details

`create(parent, body=None, x__xgafv=None)`

    Creates a tag on an Entry.
    Note: The project identified by the `parent` parameter for the
    [tag](https://cloud.google.com/data-catalog/docs/reference/rest/v1beta1/projects.locations.entryGroups.entries.tags/create#path-parameters)

    [tag
    template](https://cloud.google.com/data-catalog/docs/reference/rest/v1beta1/projects.locations.tagTemplates/create#path-parameters)
    used to create the tag must be from the same organization.

    Args:
      parent: string, Required. The name of the resource to attach this tag to. Tags can be attached to
    Entries. Example:

    * projects/{project_id}/locations/{location}/entryGroups/{entry_group_id}/entries/{entry_id}

    the location in this name. (required)
