---------------------------------
Attachment: TagPropagation.patch
> 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
> Priority: Blocker
> Attachments: TagPropagation.patch
>
>
> 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.
