There will be an attempt to reconcile future contributions.
From Denny Vrandecic, current Google researcher working on the Google Knowledge Graph, former project director of Wikidata [1]:
"Freebase has seen a huge amount of effort go into it since it went public in 2007. It makes a lot of sense to make the results of this work available to Wikidata. But knowing Wikidata and its community a bit, it is obvious that we can not and should not simply upload Freebase data to Wikidata: Wikidata would prefer the data to be referenced to external, primary sources.
"In order to do so, Google will soon start to work on an Open Source tool which will run on Wikimedia labs and which will allow Wikidata contributors to find references for a statement and then upload the statement and the reference to Wikidata. We will release several sets of Freebase data ready for consumption by this tool under a CC0 license. This tool should also work for statements already in Wikidata without sufficient references, or for other datasets, like DBpedia and other machine extraction efforts, etc.
"To make sure we get it right, we invite you to participate in the design and development of this tool here:
