    Introduction Increasingly often research in the humanities is based on data. This change in attitude and research practice is driven to a large extent by the availability of small and cheap yet high-quality recording equipment (video cameras, audio recorders) as well as advances in information technology (faster networks, larger data storage, larger computation power, suitable software). In some institutes such as the Max Planck Institute for Psycholinguistics, already in the 90s a clear trend towards an all-digital domain could be identified, making use of state-of-the-art technology for research purposes. This change of habits was one of the reasons for the Volkswagen Foundation to establish the DoBeS program in 2000 with a clear focus on language documentation based on recordings as primary material.

    ELAN is a multimedia annotation tool that has been developed for roughly ten years now and is still being extended and improved in, on average, two or three major updates per year. This paper describes the current state of the application, the main areas of attention of the past few years and the plans for the near future. The emphasis will be on various interoperability issues: interoperability with other tools through file conversions, process based interoperability with other tools by means of commands send to or received from other applications, interoperability on the level of the data model and semantic interoperability.

    In the AVATecH project the Max-Planck Institute for Psycholinguistics (MPI) and the Fraunhofer institutes HHI and IAIS aim to significantly speed up the process of creating annotations of audio-visual data for humanities research. For this we integrate state-of-theart audio and video pattern recognition algorithms into the widely used ELAN annotation tool. To address the problem of heterogeneous annotation tasks and recordings we provide modular components extended by adaptation and feedback mechanisms to achieve competitive annotation quality within significantly less annotation time. Currently we are designing a large-scale end-user evaluation of the project.
