Miguel Carrillo added a comment - 08/Oct/14 11:24 AM Dear Alberto, Let me clarify that "Open Data" as we use it is a concept that has a different nature. Although the idea is wider ( http://en.wikipedia.org/wiki/Open_data ), a typical scenario and the one we normally focus on is Smart Cities. Open Data could be a Town Council publishing different statistics (real time data of electricity consumption, demographics, etc.) Best regards, Miguel El 08/10/2014 11:05, Alberto Guillén Perales escribió: Hello, thanks for the reply. It is true that Open/LibreOffice can open these documents, however, it is not a matter of "usability" but of image and "philosofy". If FIWARE promotes the idea of open data, the distribution of information using proprietary formats seems incongruent. Nonetheless, I'm fascinated with the project . Best regards. Alberto.

Most (if not all) the presentations can be opened also with Open/LibreOffice, with minor issues that do not affect the overall message. If, by chance, you find a presentation that you cannot open, let us know which is the file.

Best regards. Alberto.
