FAQ
JML to GBR 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 GBR files?
GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.
