Our (web)app diggr+ can be used together with Exabis ePortfolio. Data generated by this app is stored to the ePortfolio module. 

diggr+ combines competency grid work with ePortfolio work. All artifacts produced with diggr+ are stored in the exabis ePortfolio module in Moodle. This allows for cross-course work in various didactic settings.

Before using the app, the "exabis ePortfolio" block must be installed in the respective Moodle installation.
