  Recently, platform ecosystem has received attention as a key business
concept. Sustainable growth of platform ecosystems is enabled by platform users
supplying and/or demanding content from each other: e.g. Facebook, YouTube or
Twitter. The importance and value of user data in platform ecosystems is
accentuated since platform owners use and sell the data for their business.
Serious concern is increasing about data misuse or abuse, privacy issues and
revenue sharing between the different stakeholders. Traditional data governance
focuses on generic goals and a universal approach to manage the data of an
enterprise. It entails limited support for the complicated situation and
relationship of a platform ecosystem where multiple participating parties
contribute, use data and share profits. This article identifies data governance
factors for platform ecosystems through literature review. The study then
surveys the data governance state of practice of four platform ecosystems:
Facebook, YouTube, EBay and Uber. Finally, 19 governance models in industry and
academia are compared against our identified data governance factors for
platform ecosystems to reveal the gaps and limitations.
