The best way to handle them depends on what you want to do. You need to actually download the NAF files rather than countries or other small files as different kinds of data will be organized differently. Just don't try to read multigigabyte files in a text editor :) If you start with one of the giant XML files, the first thing you'll probably want to do is extract just the elements that are interesting to you. A short string parsing or SAX routine in your language of choice should let you get the information in a format you like. If you download the linked data files and you're interested in actual headings (as opposed to traversing relationships), grep and sed in combination with the join utility are handy for extracting the elements you want and flattening the relationships into something more convenient to work with. But there are plenty of other tools that you could also use. If you don't already have a convenient environment to work on, I'm a fan of virtualbox. You can drag and drop things into and out of your regular desktop or even access it directly. That way you can view/manipulate files with the linux utilities without having to deal with a bunch of clunky file transfer operations involving another machine. Very handy for when you have to deal with multigigabyte files. kyle On Mon, Sep 29, 2014 at 11:19 AM, Jean Roth <[log in to unmask]> wrote: > Thank you!
