             Summary: Classification propagation from entity to a derivative or child entity
                 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
             Fix For: 0.9-incubating


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 puproses. 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 entiity should have the union of all classifications of each source entity.
Business Terms:
Child business terms should inherit the classifications associated with the parent term.
The option to propagate classification 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 all supported data asset types in Atlas, 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 folder in HDFS 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 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 there are different values for attributes on tags (classifications) then a dialog user needs to be prompted for action to resolve the conflict. Once resolved, the resolved value will be carried forth to derivative assets.
