Actually, my suggestion would be to switch on Primary Sources as a default tool for everyone. That should increase exposure and turnover, without compromising quality of data.

Hi Gerard,
given the statistics you cite from
https://tools.wmflabs.org/wikidata-primary-sources/status.html
I see that 19.6k statements have been approved through the tool, and 5.1k statements have been rejected - which means that about 1 in 5 statements is deemed unsuitable by the users of primary sources.
Given that there are 12.4M statements in the tool, this means that about 2.5M statements will turn out to be unsuitable for inclusion in Wikidata (if the current ratio holds). Are you suggesting to upload all of these statements to Wikidata?
Tpt already did upload pieces of the data which have sufficient quality outside the primary sources tool, and more is planned. But for the data where the suitability for Wikidata seems questionable, I would not know what other approach to use. Do you have a suggestion?
Once you have a suggestion and there is community consensus in doing it, no one will stand in the way of implementing that suggestion.
Cheers, Denny

Another; make a kind of worklist on Wikidata that reflect the watchlist on the clients (Wikipedias) but then, we often have items on our watchlist that we don't know much about. (Digression: Somehow we should be able to sort out those things we know (the place we live, the persons we have meet) from those things we have done (edited, copy-pasted).)
I been trying to get some interest in the past for worklists on Wikipedia, it isn't much interest to make them. It would speed up tedious tasks of finding the next page to edit after a given edit is completed. It is the same problem with imports from Freebase on Wikidata, locate the next item on Wikidata with the same queued statement from Freebase, but within some worklist that the user has some knowledge about.
Imagine "municipalities within a county" or "municipalities that is also on the users watchlist", and combine that with available unhandled Freebase-statements.

If you have the article on your watch-list, then you will get a warning that says "You lazy boy, get your ass over here and help us out!" Or perhaps slightly rephrased.

Hi Gerard, hi all,
The key misunderstanding here is that the main issue with the Freebase import would be data quality. It is actually community support. The goal of the current slow import process is for the Wikidata community to "adopt" the Freebase data. It's not about "storing" the data somewhere, but about finding a way to maintain it in the future.
The import statistics show that Wikidata does not currently have enough community power for a quick import. This is regrettable, but not something that we can fix by dumping in more data that will then be orphaned.
Freebase people: this is not a small amount of data for our young community. We really need your help to digest this huge amount of data! I am absolutely convinced from the emails I saw here that none of the former Freebase editors on this list would support low quality standards. They have fought hard to fix errors and avoid issues coming into their data for a long time.
Nobody believes that either Freebase or Wikidata can ever be free of errors, and this is really not the point of this discussion at all [1]. The experienced community managers among us know that it is not about the amount of data you have. Data is cheap and easy to get, even free data with very high quality. But the value proposition of Wikidata is not that it can provide storage space for lot of data -- it is that we have a functioning community that can maintain it. For the Freebase data donation, we do not seem to have this community yet. We need to find a way to engage people to do this. Ideas are welcome.
What I can see from the statistics, however, is that some users (and I cannot say if they are "Freebase users" or "Wikidata users" ;-) are putting a lot of effort into integrating the data already. This is great, and we should thank these people because they are the ones who are now working on what we are just talking about here. In addition, we should think about ways of engaging more community in this. Some ideas:
(1) Find a way to clean and import some statements using bots. Maybe there are cases where Freebase already had a working import infrastructure that could be migrated to Wikidata? This would also solve the community support problem in one way. We just need to import the maintenance infrastructure together with the data.
(2) Find a way to expose specific suggestions to more people. The Wikidata Games have attracted so many contributions. Could some of the Freebase data be solved in this way, with a dedicated UI?
(3) Organise Freebase edit-a-thons where people come together to work through a bunch of suggested statements.
(4) Form wiki projects that discuss a particular topic domain in Freebase and how it could be imported faster using (1)-(3) or any other idea.
(5) Connect to existing Wiki projects to make them aware of valuable data they might take from Freebase.
Freebase is a much better resource than many other data resources we are already using with similar approaches as (1)-(5) above, and yet it seems many people are waiting for Google alone to come up with a solution.
Cheers,
Markus
[1] Gerard, if you think otherwise, please let us know which error rates you think are typical or acceptable for Freebase and Wikidata, respectively. Without giving actual numbers you just produce empty strawman arguments (for example: claiming that anyone would think that Wikidata is better quality than Freebase and then refuting this point, which nobody is trying to make). See https://en.wikipedia.org/wiki/Straw_man

Hoi, When you analyse the statistics, it shows how bad the current state of affairs is. Slightly over one in a thousanths of the content of the primary sources tool has been included.
Markus, Lydia and myself agree that the content of Freebase may be improved. Where we differ is that the same can be said for Wikidata. It is not much better and by including the data from Freebase we have a much improved coverage of facts. The same can be said for the content of DBpedia probably other sources as well.
I seriously hate this procrastination and the denial of the efforts of others. It is one type of discrimination that is utterly deplorable.
We should concentrate on comparing Wikidata with other sources that are maintained. We should do this repeatedly and concentrate on workflows that seek the differences and provide workflows that help our community to improve what we have. What we have is the sum of all available knowledge and by splitting it up, we are weakened as a result. Thanks, GerardM

Also, Freebase users themselves who did daily, weekly work.... some where passing users, some tried harder, but made lots of erroneous entries (battling against our Experts at times). We could probably provide a list of those sorta community blacklisted users who'sdata submissions should probably not be trusted.
+1 for looking at better maintained specific properties. +1 for being cautious for some Freebase usernames and theirentries. +1 for trusting wholesale all of the Freebase Experts submissions. We policed each other quite well.

+1, I think that's your best bet. Specific properties were much better maintained than others -- identify those that meet the bar for wholesale import and leave the rest to the primary sources tool.

From experience with the Primary Sources tool proposals, the quality is mixed. Some things it proposes are really very valuable,but other things are also just wrong. I added a few very useful facts and fitting references based on the suggestions, but I also rejected others. Not sure what the success rate is for the cases I looked at, but my feeling is that some kind of "supervised import" approach is really needed when considering the total amount of facts.
An issue is that it is often fairly hard to tell if a suggestion is true or not (mainly in cases where no references are suggestedto check). In other cases, I am just not sure if a fact is correct for the property used. For example, I recently ended up accepting "architect: Charles Husband" for Lovell Telescope (Q555130), but to be honest I am not sure that this is correct: he was the leading engineer contracted to design the telescope, which seems different from an architect; no official web site uses the word "architect" it seems; I could not find a better property though, and it seemed "good enough" to accept it (as opposed to the post code of the location of this structure, which apparently was just wrong).

It would indeed be interesting to see which percentage of proposals are being approved (and stay in Wikidata after a while), and whether there is a pattern (100% approval on some type of fact that could then be merged more quickly; or very low approval on something else that would maybe better revisited for mapping errors or other systematic problems).
