ABSTRACTrepovizz is an integrated online system capable of structural formatting and remote storage, browsing, exchange, annotation, and visualization of synchronous multi-modal, time-aligned data. Motivated by a growing need for data-driven collaborative research, repovizz aims to resolve commonly encountered difficulties in sharing or browsing large collections of multi-modal datasets. At its current state, repovizz is designed to hold time-aligned streams of heterogeneous data: audio, video, motion capture, physiological signals, extracted descriptors, annotations, et cetera. Most popular formats for audio and video are supported, while CSV formats are adopted for streams other than audio or video (e.g. motion capture or physiological signals). The data itself is structured via customized XML files, allowing the user to (re-) organize multi-modal data in any hierarchical manner. Datasets are stored in an online database, allowing the user to interact with the data remotely through a powerful HTML5 visual interface accessible from any current web browser; this feature can be considered a key aspect of repovizz since data can be explored, annotated, or visualized from any location.

repovizz has been developed by the Music Technology Group of Universitat Pompeu Fabra in the context of large-scale research projects over the past few years, and now it is close to launching as beta. In this seminar we'll give an overview of the main capabilities of repovizz and its current state of development, followed by a short tutorial.
