About

Visual Tag Chooser

The Visual Tag Chooser is an application designed to select and edit tags and to make JOSM (Java OpenStreetMap Editor) preset files for the HOT Exports Tool.

The HOT Export tool requires a list of tags to be specified when downloading an extract.
This list is generated by a user uploading a JOSM Preset XML file. The preset file is a structured format
with groups of tags, translations of tags, defaults etc. Creating and editing a preset is essential
for the HOT Exports application. That process is not easy at all for users and involves
text editing a raw XML file.

Solution
An application that will create and edit a JOSM preset visually using a more user friendly interface.

Limitations
It misses out the more complex JOSM preset XML features such as auto increment, expressions, matches, display values and roles.

User Guide & more information
See docs in docs directory

Internationalisation

Strings in i18n/code.yml (e.g i18n/en.yml)
Partials can be localized - for example home.en.erb
Ensure you use the localized_erb method instead of the usual erb method
