The paradigm of Open Science is based on the tiers Open Access, Open Data and Free Open Source Software (FOSS). However, the interconnections between the tiers remain to be improved. This is a critical factor to enable Open Science.
This Townhall meeting reaches out all across EGU, especially welcoming Early Career Scientists, to network and discuss the current challenges and opportunities of the FOSS tier, including:

- the easy approach to choosing software licences

- recognition for scientific software: how to write a software paper?

- software life cycle: who will maintain your software after you've finished your PhD and found a decent job?

- funding software development: evolving software begun for your own research needs into something larger, that serves other's needs, and boosts your scientific reputation.

- software reviews: how to set up software development such that other developers get involved in an early stage?

- how can OSGeo help you with all these questions?

The Open Source Geospatial Foundation, or OSGeo, is a not-for-profit umbrella organization for Free and Open Source geospatial tools, including QGIS, gvSIG, GRASS GIS, Geoserver and many others. OSGeo is hosting this Townhall event to support the collaborative development of open source geospatial software by promoting sustainable Open Science within EGU.
