Could it be possible to create some kind of info
(notification?) in a
wikipedia article that additional data is available in a queue ("freebase")
somewhere?
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
