This thread is an exploration of the question: What is data? To who or what is it handed over or where does it come form? Each electronic transaction leaves a trace of raw data, but raw for one, is like petrol for another: profiling of users is done in the interest of marketeers and advertisers, for state surveillance or to control the workplace; different practices all based on the extraction of information from data. In the form of games, statistical manipulation and discussion, V/J12 tries to decode and put its finger on the issues that weigh on the registrations that are stored in logs and databases. While doing so, we carefully approach that strange species called ’data’, always ready to mutate, multiply and never loyal to its origins.
