Graffiti Markup Language is the latest F.A.T. project. You probably know their graffiti-related software projects: Graffiti Analysis, Laser Tag and EyeWriter. 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. The week F.A.T. will publish new GML related projects each day!
