Kura is a multi-user open-source linguistic database especially geared towards language description. The application consists of four independent parts: an application framework that works with the data from the database, and a gui-framework that the user to work with the data, a server that can present the data in html form over the Internet, and finally a project that is used to generate a pdf version or an html version of a linguistics text that uses the information from the database.
The next generation of Kura will focus on the needs of language documentation projects and contain an analyzation software to support the development of grammars and dictionaries from the annotated data.
