How to upload your software to the ETH Data Archive:

This service is provided by ETH Library to affiliates of ETH Zurich. You may deposit software you developed as part of your employment with ETH Zurich.

ETH Zurich uses the ETH Data Archive as a repository for Open Source Software and for software licensed under proprietary license terms to a third party. All software registered as Open Source Software can be downloaded directly from the ETH Library.
