At the Web Congress in Barcelona, ​​I attended a workshop on Open Data in wich Martín Alvarez Espinar, W3C Spanish Office's head, and Jordi Graells i Costa, coordinator of content and innovation of the Generalitat de Catalunya, explained what is the international initiative Open Data, and how it is developed in concrete projects in some communities of Spain, as Asturias and Catalonia.

Hadoop is an Apache project that provides an environment that supports the management of large amounts of data. Such systems are typically used to support the large amount of information generated by great social networks, especially when relational databases are beginning to have problems of scalability, or the cost of growth is too high.

A good source of inspiration for anyone eager to create a scorecard where we could see these evolve dynamically as so well chosen indicators.

Surely more than one person has clicked on an indicator in the chart to see if anything more;)..
