In open data, should I understand open to mean:
- Free as in speech
- Free as in beer, gratis
- Something else?
For example, the Swedish Meteorological and Hydrological Institute (SMHI) has dedicated itself to open data, and more and more of its products will be available with free licenses; first for non-commercial uses, but later without usage instructions.
For some data, such as data archived on tape, they will still ask for a one-time distribution fee, I think to cover costs they need to make to retrieve the data. The data are still freely licensed, so the user is free to put it on the web etc.
Is this still "open data"? The data in question is licensed under CC BY 2.5 (Swedish link).
