Graffiti Markup Language is the latest F.A.T. project. You probably know their graffiti-related software projects: Graffiti Analysis, Laser Tag and EyeWriter and their two new iPhone apps, DustTag and FatTag Deluxe: Katsu Edition. These use now the Graffiti Markup Language, a new XML file type specifically designed for archiving graffiti tags. The .gml text files can be uploaded and downloaded on 000000book.com.
