JOSM, an openstreetmap editor written in the Java programming language, provides some “presets” which allow the user to tag objects easily just by selecting it from a menu. This menu and the corresponding dialogs are all defined in a huge XML file, presets.xml. It allows to define menu entries, subgroups and finally dialogs with standard GUI controls such as checkboxes, comboboxes, line edits, labels, icons etc.
The aforementioned presets.xml is included in josm.jar, but JOSM even can load such presets over a networking connection (http). This makes it easy for users to create and use their very own presets, maybe for specialized use cases like event mapping, mapping ski pistes or nautical stuff.
If you have further requests, do not hesitate to open a trac ticket. It’s even possible to do this as anonymous user, so there’s no excuse :) .
