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.
Cheers, Denny
Hoi, If I understand you well, what you propose is adding links that are similar to what we already do to VIAF and so many others. 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" vrandecic@google.com:

Hello All,
We already do have a freebase ID, similar to the VIAF one- it's P646http://www.wikidata.org/wiki/Property:P646.
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.

License nitpicking is good of course,

but I disagree that we should speculate about people's intention when they contribute valid information, especially to a data project like Wikidata which mostly contains "facts" (!= truth, sure) and obviously needs to be maintained by something more than just the usual suspect (the same overworked Wikipedians).

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.

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. With apologies,
Maximilian Klein Wikipedian in Residence, OCLC +17074787023

Hi Denny,
I asked again about this property because there were some concerns when it was created. From the comments I infer that the general ethos is "not against, but not thrilled either": https://www.wikidata.org/wiki/Wikidata:Project_chat#Freebase-Wikidata_mappin...
I share the feeling, I don't mind linking, but I see little utility for Wikidata given the different licenses.

Think of it this way, it is clear freebase / Google already has such mappings and probably using them as they are the ones that provided them to us.
I don't see that us also adding the data for the mappings on our side is going to mean anything... they already know what on freebase links to what on Wikidata...

Wikidata links to numerous external databases with other licenses than CC0, I don't follow your argument about incompatible licenses.
I hope that Wikidata will become an increasingly important identity hub for the whole Web that everyone can use and share in. The more knowledge bases we can tie together, link together, the more useful Wikidata, the more useful the Web of Data will be.
As I said before, I would like to see this data uploaded to Wikidata, but this is a decision for the community. I think it would be of benefit to users of the Wikidata data to be able to use tools and bots that can integrate from a variety of different knowledge bases and to have as many identity reconciliation data available as possible.

Is there agreement and a license that allows for this? Thanks, GerardM Op 11 nov. 2013 19:35 schreef "Denny Vrandečić" vrandecic@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%3E
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.
Cheers, Denny

=)) I am very happy to hear this.
Also, the mapping is awesome.

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. With apologies,
Yours too, Max.
Thank you both for your very good work.

Google would not have sent over a large chunk of cash to help get Wikidata started if it didn't think it could use Wikidata. That Russian search engine comany would not have sent over a large chunk of cash to keep Wikidata going if it didn't think it could use Wikidata.
That doesn't mean Google is being malicious (about this, at least), it means that they are making a business decision. As long as Google doesn't try to make decisions about Wikidata content or operations - something it would have no economic reason to do anyways - I don't have a problem with that. Just don't pretend that Google is doing this out of the goodness of ther hearts. On Nov 11, 2013 6:27 PM, "Cristian Consonni" kikkocristian@gmail.com wrote:

Another important thing to note in this context is that all funding for Wikidata so far had the form of donations, which is crucially different from sponsoring (where you get something in return). The donors who give their money hope, of course, that the project will do something that they will find useful, but they exercise no control whatsoever in the development process. The donations are not bound to any condition, not even reporting, and there is no way to retract them. So each donor's initial intentions, whatever they were, have no influence on the execution of the project (moreover, I Kant think of any reason why the intentions rather than the outcome should determine the value of the deed ;-).
Cheers,
Markus

We did have to provide reports. It was very light-weight, but the donors wanted to make sure we spent the money on the project :)
