A schematic diagram describing the MINERVA architecture. The back-end—webserver—handles data upload of SBGN-compliant model(s) to the database (‘Structured model’), its annotation (‘Annotated model’) and integration with other provided source files, like pre-defined overlays, overview images and data mining results. The front-end displays the models visualized with the Google Maps API, including overlays based on custom, user-provided datasets. Moreover, the webserver handles search queries, either to the model or to external databases, and visualizes the query results. Finally, a selected part of the model can be exported either as a SGBN-compliant model (.xml file) or as an image (.png or .pdf). A separate view allows exporting network contents or structure.
