I think that recording works with their original titles would make up for a more consistent and professional database.
As an example, "La vita è bella" instead of "Life is Beautiful". "Life is Beautful" would be added to AKA's.

I just replied over here where you asked another question about language. *linkylink*

Hello all,I am new to this site, and the one sticking point stopping me from diving in and contributing straight away is the worry that I will be duplicating or wasting effort done elsewhere on the web. I noticed, for example, that some efforts have been made to import a large number of articles from Wikipedia. Was this a one-off effort, or is there some sort of periodic refresh?I am thinking in particular about volatile data, such as the properites of sports teams. Current championships, owners, etc. can change often, squads and rosters change at least annually. Does this information need to be maintained concurrently with Wikipedia? If the types start include things such as number of appearances and goals scored by individual players, then the update frequency switches to weekly.With the vast number of contributors keeping the WIkipedia articles up-to-date, it will always be the de facto "master". I don't think Freebase needs to (or should) compete with this, rather its power is in the ability to formally stucture the data and allow meaningful queries and extracts. This power is significantly diluted if the topic diverges from the master article.What is the Freebase policy on this? Is the assumed that topics will be maintained in situ or is it actually preferred to refresh from alternative sources? Or does the very nature of the site discourage volatile information in favour of static data?- John

We have an excellent presentation about how we mine wikipedia posted on our blog, here. Hopefully that will answer most of your questions. If you have any more after watching, please let us know! I can put you in touch with people who work on our data pipeline, if necessary.

Many thanks for the reply, the article was very interesting.
I am still unclear about the long-term relationship between the two repositories. Is the data that has been mined from Wikipedia a "slave" of the source or a divergant copy?
I guess fundamentally what I am trying to understand is: should I bother manually filling in fields in Freebase articles (transcribing data that is already in the Wikipedia article), or should I wait for some clever person to write a app that automatically mines the data?
-
Yes, please do fill in fields here!
Your work will never be overwritten from Wikipedia, and while we do hope to get a LOT of information from there, it's an ongoing process, so we'd rather our community helped us where possible with individual snippets of data, until we are able to mine everything.

I was looking at an entry in which 2 people were listed as "Influencers of this person". How can I tell how it got there and if anyone else agrees with this?
BTW, I am new to this DB, so if this is answered somewhere, just leave a pointer to the answer. Thanks.

Roger, you can look at the “Page History” link for any topic and see when and by whom assertions about a topic were added or removed. For example, your user history. We don’t currently have a model for other users to agree with an assertion, however.

I am having problems to do some research on Freebase, and my doubt is if this is cause I'm not using it the way it was designed for, or it just don't have enough data yet.
For example, I was trying to search by Nightwish Music Videos from every albums. I can search by Nightwish and then filter their albums, what works fine, but there's not a type for 'Music Videos', also, if I filter by 'film' and 'media' I get just some movies that has Nightwish songs.

Bemvindo, Paulo. We have a lot of data about recorded music, but we do not have a lot of information about music videos, nor have we done a lot of modeling of what music video data would look like. If you want to help out, you could prototype music videos in your personal domain, or join the music modeling interest group and comment there. Thanks in advance for any suggestions you may have.
-
Addendum: the music modeling interest group is here.

Is there a recommended source for album/film/book cover art? How does the licensing for that kind of thing go? When it's available on the artist or author website, or if it's on amazon, is that in the public domain?
-
Hey, Lisa.
Generally, album, film, and book art is copyright by the publisher; images put on someone’s Web site do not become public domain unless the owner explicitly declares so. By default, an image should be assumed to be copyright by its creator.
Images uploaded by Freebase users must comply with the Freebase Contribution Guidelines; specifically, images must be in the public domain, compatible with a CC-by license, or owned by the user, who agrees to license them CC-by by uploading them. Thanks for asking!

On the one hand you state that the data (and schema) are CC-BY but on the other you state that the API cannot be used to duplicate you Site or Service.
Exactly what Site or Service am I NOT permitted to duplicate?
More specifically, am I allowed to utilize the type schema in a commercial application designed to help users organize their own data with said schema? (i.e. Can I develop and commercialize an application that is "compatiable" with the freebase type-schema?)
-
Hey Jason. Sorry for the confusion on this one! We're actually in the process of reviewing the Terms of Service in order to clarify a lot of the issues around licensing and reuse of the data. Hopefully by the end of the month we'll have a much clearer, updated version that we can then submit to the community for feedback.
The short answer is that the schema is licensed under CC-BY, as you noted, so please feel free to use it in your commercial app. The only thing we ask is that you attribute it back to the Freebase community, as outlined in the license terms.
Thanks for bringing this to our attention, and just let us know if you have any other questions.

Upload the taxonomic tree of life?
-
Hey, Dan. I have to admit that I'm not sure what you mean by the taxonomic tree of life. If it's domain-specific, and you want feedback on the idea, I'd suggest posting in the relevant domain. Otherwise, can you give a little more info on what you're proposing?
-
There's some work already underway in this area - check out the discussions going on in the biology domain and see if that's along the lines of what you had in mind.
