             Summary: Tag propagation from object to child object or derivative asset
                 Key: ATLAS-2469
                 URL: https://issues.apache.org/jira/browse/ATLAS-2469
             Project: Atlas
          Issue Type: New Feature
            Reporter: pratik pandey
            Assignee: pratik pandey


User Story:

As a data steward i need a scalable way to quickly and efficiently propagate tags for efficient searches and tag based security. Likewise tags for derivative dataset should be inherited from the parent. For example, if an entity is tagged "Secret" then resulting entity created from a CTAS operation should also be tagged "secret" to maintain the classification of the parent. In the case where 2 or more datasets are aggregated the derivative dataset should be a union of all parent tags.


Terms:

* Child business terms should inherit the tags associated with the parent term.
* the option to propagate tags to child business terms in a hierarchy should be provided
* Ability to update the propagated tags manually via UI or through the API
* Tagging a term should propagate to data assets that are already attached to that business term as well

Data assets

* For supported components in HDP 2.6,if a derivative asset is created it should inherit the tags and attributes from the original asset.
* the option to propagate tags to child entities should be provided (e.g. if you tag a hdfs folder optionally tag all the files within it)
* Ability to update the propagated tags manually via UI or through the API
* Tagging a parent object should be inherited even after child creation dynamically (unless a flag is set not to do this)
* Derived data assets should have the tags of the original data asset.

conflict resolution - if the different values for attributes then a UX dialog that prompts user for action needs to be provided. Once resolved, the resolved value will be carry forth to derivative dataset.
