The objective was to analyze the intersections among the data life cycle model elements of the DCC, DataONE and CVD-CI initiatives. It is a descriptive, qualitative and bibliographical research. It was verified that there are correspondences between stages (not always one-to-one) of the analyzed data life cycles. It was possible to verify that the CVD-CI condenses several activities in a single step, which can hinder its applicability. In general, the proposed models still need to be further detailed so that they can be directly applied by researchers/curators.
