This work represents a review of the practical application, work done and near-future perspectives of an open scientific lifecycle model. The EcoNAOS (Ecological North Adriatic Open Science Observatory System) project is an example of the application of Open Science principles to long term marine research. For long term marine research we intend here all the marine research projects based on Long Term Ecological Data. In the paper, the structure of the lifecycle, modeled over Open Science principles, will be presented. The project develops through some fundamental steps: database correction and armonization, metadata collection, data exploitation by publication on a web infrastructure and planning of dissemination moments. The project also foresees the setting up of a data citation and versioning model (adapted to dynamic databases) and a final guidelines production, illustrating the whole process in detail. The advancement state of these steps will be reviewed. Results achieved and expected outcomes will be explained with a particular focus on the upcoming work.
