Open Data is a philosophy to make data public & accessible on the internet. Governmental data, expenditures and investments, economic indicators, resources exploit, anonymous medical information, weather information, genomics, or universe exploration to cite a few. I.e. Data.gov & Data.gov.uk are good sources of governmental data from US & UK government respectively.
This movement is a prerequisite for other ones like:
- Open Government to add transparency to the work of our politicians or
- Open Science where science facts and research papers are freely shared on the net for anyone to conduct a further research today or in the future on the current knowledge. That what Newton referred as “If I have seen further it is by standing on the shoulders of giants” and it is one of the best way to boost the human knowledge and scientific progress.
In these days we are living, one can argue we are surrounded by tons of data, and more and more our capacity to process it is rapidly saturated and filtering mechanism are more needed than ever to reduce the noise over the signal.
On other hand, not all the relevant data is published. Not all is in digital form, not all is available for others. Providing fast and cheap publication mechanism can help to spread openData with valuable one.
