>                 Key: ATLAS-1821
>                 URL: https://issues.apache.org/jira/browse/ATLAS-1821
>             Project: Atlas
>          Issue Type: Improvement
>          Components:  atlas-core, atlas-webui
>            Reporter: Srikanth Venkat
>            Priority: Major

> User Story:
> As a data steward, I need a scalable way to quickly and efficiently propagate classification across the information supply chain to support efficient searches and classification based security for compliance and audit purposes. 
> This requires:
> 1. Classifications for derivative entities should be inherited from the originator and to child entities from parent. 
> For example, if a Hive column is classified "Confidential" then resulting column created from a CTAS operation should also be tagged "Confidential" to maintain the classification of the original entity. In the case where 2 or more entities are composed, the derivative entity should have the union of all classifications of each source entity.
> 2. Business Terms:
> a. Child business terms should inherit the classifications associated with the parent term.
> b. The option to propagate classification to child business terms in a hierarchy should be provided
> c. Ability to update the propagated tags manually via UI or through the API
> d. Tagging a term should propagate to data assets that are already attached to that business term as well
> 3. Data assets
> a. For all supported data asset types in Atlas, if a derivative asset is created it should inherit the tags and attributes from the original asset.
> b. the option to propagate tags to child entities should be provided (e.g. if you tag a folder in HDFS optionally tag all the files within it)
> c. Ability to update the propagated tags manually via UI or through the API
> d. Tagging a parent object should be inherited after child creation dynamically (unless a flag is set not to do this)
> e. Derived data assets should have the tags of the original data asset.
> Conflict resolution - if there are different values for attributes on tags (classifications) on upstream or parent entities used to derive a data asset then user needs to be prompted for action to resolve the conflict. Once resolved, the resolved value should be carried forth to derived assets.
