Marc, You mean the tool for the BAG import? Well they must have rewritten it by now, as they are in 'maintenance' mode, nowadays. I haven't looked into it very deeply, it's simply something that occurred to me on their 'nieuwjaarsborrel'. They already have a tool that works and it could work for us as well if we can feed it our data.
