What are good open data sources for open data?

data.gov is nice but limited to American open data.

datahub.io is based on CKAN, it comes closes to what I have in mind and it has an API. There's also a list of CKAN instances.

Are there other, similar initiatives?

  • It seems like your question might be very similar to opendata.stackexchange.com/questions/3516/… – Mark Silverberg Aug 13 '14 at 20:52

    @Skram : taxonomies are about classifying the sites ... I'd have said it's closer to : opendata.stackexchange.com/q/266/263 – Joe Aug 14 '14 at 15:55
  • I would agree with Skram and Joe, both these posts are good answers to this question – Andrew - OpenGeoCode Aug 14 '14 at 16:54
  • Just a note that Data.gov has a great deal of data that covers others countries, either posted on behalf of the United Nations, World Bank, or data gathered during scientific experiments globally (e.g., NASA satellite images). (Note: I am the Evangelist for Data.gov.) – Jeanne Holm Aug 28 '14 at 11:08

I'm not really sure that a StackExchange site is the best way to organize the kind of information you're looking for. I actually think a Wikipedia category is more appropriate and, indeed, one already exists. The CC-licensed data subcategory looks particularly useful and could be expanded.

    This does not provide an answer to the question. To critique or request clarification from an author, leave a comment below their post. – philshem Aug 22 '14 at 20:46
  • @philshem I completely disagree with your flag. While I editorialize a bit, this does in fact provide a perfectly reasonable answer to the question considering the question is: "Where can I find a list of open data?" and my answer is: "The largest collection of open data in the world." – Thomas Aug 22 '14 at 21:31
  • Was referring to your first sentence. – philshem Aug 22 '14 at 22:02
  • Wikipedia is open with an ok API, but its data is almost never structured nice enough to classify as "open data". If only this info was on Wikidata or dbpedia. – kqw Aug 23 '14 at 20:21

Check out opendata.arcgis.com/explore.json. It's a good source for open data that is (mostly) spatial. Soon there will be a master search to look through all these sites at opendata.arcgis.com. There will also be a showcase of individual sites you can link to from there.

Full disclosure: I'm a product engineer on the Esri Open Data team.

  • I don't think it's a big deal in this case but you should be careful to disclose that you work with ESRI when linking to resources by your own company/team. I think this is inline with the self promotion info at opendata.stackexchange.com/help/behavior – Mark Silverberg Aug 20 '14 at 17:01
  • Thanks Skram, will do in the future. I'm new to the community and stack exchange in general so I'd love to help out around here in the right way. – Daniel Fenton Aug 20 '14 at 17:04
  • totally! Y'all are doing some interesting stuff over @ ESRI DC. I've met a few of your coworkers. – Mark Silverberg Aug 20 '14 at 17:06

http://opendata.stackexchange.com fits your requirements since:

  • it is precisely about open data,
  • it is open data itself (cc by-sa 3.0 with attribution required).
