We could potentially automate the process of reviewing known repositories for the existence of certain files or certain keywords that could provide signal/metrics on a project's relationship to the SDGs.

Some ideas include:

• Looking for Digital Public Goods Alliance related files or keywords
• Looking for Open Source Inclusion/Onboarding Program related files or keywords (e.g. Google Summer of Code, Outreachy, UNICEF Innovation Fund, etc...)
• Looking for the specific keywords mentioned in Create a keyword list that maps to various SDGs #2
