I think that in future many people will ask for list of open datasets: by country, by argument (science, geography, art,..). Is a good idea create wiki like these? I think that this wiki could be used also to add new open datasets that you heard of. Or should we start from a question like: "Is there any dataset for Italy?" and convert it later to wiki?

I'm not sure creating a catch-all wiki for this type of misinformation is going to be good for this site.

Remember, the lifeblood of this site is search; Google Search — and if someone is searching for a "Database of politicians for Italy," I sure would like them to find this site.

In the bigger picture, this site is supposed to be about answering specific questions you encounter in your day to day work. This site isn't supposed to be a list of where to find things on the Internet. If you distilled this subject down to a few generic, catch-all lists of where to find stuff, I'm afraid you would miss out on a lot of fascinating problems people are trying to solve.

I would stick to specific questions. Let Open Data SE become a huge repository of fantastically-detailed, long-tailed questions that would serve to separate you from any ol' generic site on the subject. That's how we're going to hold the interest of the experts you are trying attract.

  • Surely the spirit of this site is, like others SE sites, a knowledge base of Q&A. What think is that many questions will be "where can I find X?" and will become FAQs creating "noise" between specific questions. This is why I'm asking if it's useful having a (single) wiki to summarize this kind of answers.

    I agree that I don't think a wikipage on this site is a good thing. I would rather have a lot of "I'm looking for X" questions that we can answer, vote on, timestamp and administer than create a single page that gains none of the benefits of the content-model of StackExchange websites.

I like this idea, but maintaining such a list might be problematic and as others point out, it's a better idea to empower search engines like Google to find those datasets.

There is a new dataset type added to Schema.org and built on the W3C's DCAT work described at http://schema.org/Dataset The use of this is likely to provide better generic search to actual datasets. A detailed description behind this is at http://www.w3.org/wiki/WebSchemas/Datasets

There is a listing of government open data sites at http://www.data.gov/opendatasites
