The MPI Archive is organised in a hierarchical structure with corpus nodes containing sessions. The sessions, in turn, contain multi-media data, annotations, lexica, etc. The archive can be searched or browsed for annotations. These annotations can then be explored on-line with the ANNEX tool, or their contents can be searched through with the help of TROVA (see Trova manual on the website http://tla.mpi.nl/tools/tla-tools/trova).

ANNEX provides different views of the annotations (much like the standalone tool ELAN) and can stream media through Flash Player. Annotations can be selected, and the selected media intervals can be played. Because it is web-based, it provides a quick and easy way to view annotations directly in the archive without having to download software or files from it. At the moment, annotations can be viewed, but not edited.
