The ability to access and use data, including personal data, can enable important value creation in the online platform economy, both generally as well as for the business users and online intermediation services involved. Accordingly, it is important that providers of online intermediation services provide business users with a clear description of the scope, nature and conditions of their access to and use of certain categories of data. The description should be proportionate and might refer to general access conditions, rather than an exhaustive identification of actual data, or categories of data. However, identification of and specific access conditions to certain types of actual data that might be highly relevant to the business users could also be included in the description. Such data could include ratings and reviews accumulated by business users on the online intermediation services. Altogether, the description should enable business users to understand whether they can use the data to enhance value creation, including by possibly retaining third-party data services.
