In web development, a mashup is a web page or application that uses and combines data, presentation or functionality from two or more sources to create new services.There are many sources for getting data (raw information). Governments are good examples.However many of those cost and have complicated licensing.For instance SMHI in Sweden sells temperature data meanwhile our neighbor country Norway gives it away for free.One would say what kind of application are you building and what data do you need?  I would say give me some interesting data and I will do a good mashup of it. I could just plot it on Google maps for instance.So the question is: Where can I get free data?Note: I'm not interested in data mining using a webcrawler!Please share your sources with me.
Where can I get free public raw data?

For general information, a good place to start might be Wikipedia's Open Data page - specifically the bottom parts of the page (Organisations promoting open data, See also, and External Links)I was going to turn the rest of this post into a list of data sources for country and regional based data ... but the Guardian UK Newspaper has already gone and compiled a World Government Data Store so no point duplicating the effort, instead I'll just point to...guardian.co.uk/world-government-data...for a catalog of a lot of different country and city level Open Data Initiatives.(It's not UK based, though it does seem to focus on English-speaking countries.)At time of edit, it contains data for UK, US, Australia, Canada, New Zealand, and Basque Spain.One thing not listed on there but worth mentioning is the Ordnance Survey UK mapping data.
