Hi Group Denny, thanks for making that clear. I did not mean to show any mistrust, and I'm sorry that I did because I really respect your work.
I regretted writing what I did after thinking about it over lunch, since it is not "Assume good faith" towards Google. Maybe one of the reasons that I was sensitive to it was because I'm representing VIAF in Wikidata, which is kind of the same as Freebase in Wikidata, and I wouldn't want people assuming bad faith about VIAF. Thanks for being clear and open about your work, its a real inspiration.

Subject: Re: [Wikidata-l] Wikidata-Freebase mappings published under CC0 Hi Max, indeed, I am not suggesting creating a new property. The data release that was made today basically provides data for P646. Cheers, Denny Regarding the off-topic part of your mail, I want to point out to my personal opinion with regards to data licensing, which was formulated before I started my current job: <http://simia.net/wiki/Free_data> . This is solely my opinion though, but it did influence my voice in the decision-making process around the license for Wikidata in my previous job.

I just went back into the email Archives and a discussion started on 6/14/2013 by Google Developer Relations person Shawn Simister[1] first proposed this property. There is large thread there about licensing, ending with Micru having an unanswered question to Shawn about how Freebase can manage its license since it mixes CC-0 and CC-BY? Off-topic: this thread is from before Denny announced that he was going to Google, I believe, is that correct? Whatever happens with licensing, and regarding Wikidata's CC0, I hope that it wasn't engineered so that Google could profit from Wikidata. I concede that this thought is mostly from paranoia, and disagreeing with a lot of Google's politics and tactics in the past.

Using data from Freebase is a tantalising option. Is there agreement and a license that allows for this? Thanks, GerardM Op 11 nov. 2013 19:35 schreef "Denny Vrandečić" <vrande...@google.com<mailto:vrande...@google.com>>: Hello all, as you know, I have recently started a new job. My mission to get more free data out to the world has not changed due to that, though. Thus, I am happy to point you today to a step in this direction. We have created a mapping of Wikidata Qids to Freebase Mids, and are publishing it under CC0, so that anyone can use it in any way they want. The file contains about 2 Million mappings. The download and all further data is available here: <https://developers.google.com/freebase/data#freebase-wikidata-mappings> In particular, I hope that the data will be uploaded to Wikidata. We also plan to upload the data to Freebase. The two-way links will ensure that systems using either knowledge base can easily merge data, go from one to the other, enrich data with each other, etc. We opted to first publish the mappings standalone, to make clear that they are under CC0. The mapping is created based on the Wikidata dumps from end of October. Wikidata Items are matched with Freebase Topics based on their respective links to Wikipedia. Each mapping says that there have been no disagreeing Wikipedia-Links and at least two agreeing Wikipedia-Links, so the data should be very clean. Furthermore, the mappings are sorted by the number of agreeing Wikipedia-Links, so it is kinda sorted by relevance. The data is in RDF format. To get the Mids as they are used in Wikidata, the replace the namespace http://rdf.freebase.com/ns/m. with /m/ The Wikidata Qids are using the Wikidata namespace, i.e. the Qids themselves are concatenated to http://www.wikidata.org/entity/ If anyone wants to take up the task to upload the data to Wikidata, I can offer to help and answer questions and to help.
