FLAT is a web-based linguistic annotation environment based around the FoLiA format (http://proycon.github.io/folia), a rich XML-based format for linguistic annotation. FLAT allows users to view annotated FoLiA documents and enrich these documents with new annotations, a wide variety of linguistic annotation types is supported through the FoLiA paradigm. It is a document-centric tool that fully preserves and visualises document structure. FLAT is written in Python using the Django framework. The user interface is written using javascript with jquery. The FoLiA Document Server (https://github.com/proycon/foliadocserve) , the back-end of the system, is written in Python with CherryPy and is used as a RESTful webservice.
