Professor Kalpana Shankar discusses public-private partnerships (PPPs) in data organizations and uses genealogy as a case study. PPPs between commercial entities and public organizations can help make data archives more sustainable through new revenue streams but also risks privatizing open data. In genealogy, while companies digitize historical records, it can alienate records from institutions and raise issues of transparency. Long-term, PPPs could lead to open data becoming proprietary through restrictive metadata or expectations of users shifting to prioritize commercial partners over public interests.
