FAQ
JML to DGN Conversion
What are JML files?
JML is the native vector format of OpenJUMP, a free GIS written in Java. The name stands for JUMP Geographic Markup Language, and the file is a text document in XML that stores one map layer: its points, lines, and polygons, together with a table of attributes for each object, such as names, numbers, and dates. It is a simplified variant of the GML standard, with the difference that the description of the attribute fields is placed at the beginning of the file itself, so the file can be opened without any extra template or schema. OpenJUMP grew out of JUMP, a project of Vivid Solutions, the authors of the widely used geometry library JTS, and JML files are still the easiest way to save and share layers between OpenJUMP users.
What are DGN files?
DGN stands for "design" and represents an extension typically used for CAD (Computer Aided Design) files created with Bentley Systems' MicroStation or with IGDS (Intergraph's Interactive Graphics Design System) — two popular programs used by architects, engineers, constructors and designers. DGN files can include sizeable building projects with a rich amount of details, usually have a very large size and can be viewed with a limited number of CAD programs.
