Subject [jira] [Commented] (ATLAS-1690) Introduce top level relationships
Date Thu, 31 Aug 2017 20:19:00 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-1690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16149536#comment-16149536
] 

Pierre Padovani commented on ATLAS-1690:
----------------------------------------

Two questions on this work:

1) Can a RelationshipType inherit from another RelationshipType?

2) If yes for #1, how does that affect tag propagation?

My use case: Given a set of metadata that belongs to a particular customer, where we use a
classification with an attribute that contains the customer id, we would want that classification
to propagate to all related entities. If we had a relationship type that was generic in nature
and specified that the classification for the customer propagated, it would be nice to be
able to specify sub-types that provide additional behaviors.
