Driving research based on large collection of data often demands in the humanities a strong collaboration between researchers and data engineers. Data are the corner stone on which the research is based. Caring about our research data is not only a good practice to drive and open our research, it's also a good way to foster collaboration between researchers and engineers. In this talk we will present how, in a Digital Humanities research project, controlling the data quality and structure through a frictionless data package leverage the a great data productivity. Please note that this talk replaces one entitled "Data flowing the right way" that was due to have been given by María Arias de Reyna, who has sent his apologies but is now unable to attend the conference.
