VISPA: A new Approach for Porting Data Analysis Workflows to the Web — •Marcel Rieger, Martin Erdmann, Robert Fischer, Christian Glaser, Gero Müller, Thorben Quast, Martin Urban, Daniel van Asseldonk, and Tobias Winchen — III. Physikalisches Institut A, RWTH Aachen

We present the most recent developments of the web browser based Visual Physics Analysis (VISPA) project, which has been successfully used in various high-energy and astroparticle physics data analyses (http://vispa.physik.rwth-aachen.de). The VISPA platform delivers a modern user interface and a framework for creating extensions written in Python and Javascript to provide dedicated functionality for individual needs. Common examples for extensions are a file browser, a code editor, or a terminal. Another key feature is the use of workspaces, i.e., machines connected via SSH providing computing power and data access using remote procedure calls. Every user-accessible machine running Python can act as a workspace, regardless of whether it is a mobile phone, a desktop machine, or even a computing cluster. The benefits of this approach can be applied to data analyses in scientific workflows. With the combination of workspaces, e.g. computing resources, and individual extensions, e.g. experiment software, VISPA represents a new approach for porting data analysis workflows to the web.
