Simply, I need some countries, states and cities names in some certain orders (eg. according to population). I just search and find articles from wikipedia, for example: Lists of cities from the country X, which has some cities of that country ordered according to population. Now, I might just use the name and location of cities/states that I choose according to some of the information presented about them (the cities/states) in wikipedia.
So, what do I have to do to use these data in a form drop-down list ( tag)?
Do I still have to attribute and make this data public and free to use somehow? I think these data will be modified somehow, especially the language and the way of display. I'm not going to copy the comparison table, instead I'm using the city properties, not presenting them.
