This is a C++ Library, developed by Ko van der Sloot, for working with the Format for Linguistic Annotation (FoLiA). The software is intended for C++ developers, and provides a high-level API to read, manipulate, and create FoLiA documents. This software is a necessary dependency for various other tools that use FoLiA.
