File Format XML Property List

This file contains arbitrary data for the font. It is a place to store application specific, user specific or otherwise arbitrary data. This file is optional. If it is not defined in the UFO, there is no lib data.


The property list data consists of a dictionary at the top level. In order to prevent conflicts in the lib, keys in the top level should follow a reverse domain naming convention (see below). It is recommended that the data stored as a value be as shallow as possible.

Reverse Domain Naming Convention

Keys in the lib should follow a reverse domain naming convention. To make your unique key, reverse your Internet domain. For example, if your Internet domain is, your reverse domain name would be com.robofab. When creating a key for storing data in the lib, use this reverse domain at the beginning of your key. For example to store settings for a script, if your Internet domain is and your script is called AccentBuilder, an appropriate key would be com.robofab.AccentBuilder.
