[dna-issues] [JBoss JIRA] Closed: (DNA-211) Federation connector should record in merge plan where every property value and child came from

Randall Hauch closed DNA-211.
-----------------------------

    Resolution: Rejected

Actually, I believe this information should be reproducible directly from the contributions, without having to store the information.  For example, if one wants to know the origination of a particular value for a property, simply iterate over the contributions that contain the property and see if the property has the supplied value.

> Sometimes called "provenance", the merge plan should record from which contribution each property value and child came.  For trivial cases, this can be recomputed using the same strategy, even when some property values are removed (because they are duplicates) or children are merged.  However, it's much better to record what was done in the first place rather than recompute them (since the strategy implementation could actually be changed).
