OGS is recognised as the Italian National Oceanographic Data Centre (OGS-NODC) within the International Oceanographic Data Exchange System of the UNESCO Intergovernmental Oceanographic Commission (IOC) since 27/6/2002. OGS as part of the IOC's network of National Oceanographic Data Centres has designated responsibility for the coordination of data and information management at national level. The oceanographic database covers the fields of marine physics, chemical, biological, underway geophysics and general information on Italian oceanographic cruises and data sets. The data center manages large sets of marine and ocean data, originating from our institute and from other parties in our country, in a variety of data management systems and configurations. A major objective and challenge is to provide an integrated and harmonised overview and access to these biodiversity datasets through the GBIF network. The harvesting of marine (near) real-time data with multiple data formats, the conversion in a homogeneous and standard format, the structuring in a database and, finally, the automation of the marine data validation is obtained using XML and OGC (Open Geospatial Consortium) standards for data transport and representation. The adoption of Sensor Web Enablement (SWE) specifications enables real time integration of data and metadata, related to the data processing and calibration, the data collection instruments and the data quality control. Our technological choice is led by the requirements of interoperability, as ability to cooperate and exchange information, and resilience, as ability of adaptation to new needs. The international standard SensorML has been used as a profile, adapted to our needs and results as a joint effort of the Italian RITMARE, the European SeaDataNet, Eurofleet and ODIP community.
