Stefano Nativi is the head of the Florence Division of the Institute of Atmospheric Pollution Research (CNR-IIA) of the National Research Council of Italy. He coordinates the Earth and Space Science Informatics (ESSI) laboratory of CNR-IIA that has been developing and operating the Discovery and Access Broker (DAB) of the Global Earth Observation System of Systems (GEOSS) managed by the Group on Earth Observation (GEO). He founded the Earth and Space Sciences Informatics (ESSI) Division of the European Geosciences Union (EGU), serving as president of the division for first five years. He is a member of the GEO Infrastructure Implementation Board (IIB) and served as co-chair of the GEO Science & Technology Committee. He is also a member of the Copernicus Marine Environment Monitoring Service Scientific and Technical Advisory Committee. In the Research Data Alliance (RDA), he co-chairs the “Brokering” Interest Group (IG). For OGC (Open Geospatial Consortium), he co-chairs the Earth Systems Science Domain WG (ESS DWG) and the netCDF Standardization WG (NetCDF SWG). He has taught at the Universities of Padua (Italy), Jena (Germany), and Florence (Italy) for more than ten years. Currently, he is Visiting Scientist at the Joint Research Centre (JRC) of the European Commission, in Ispra (Italy).
The presentation will introduce the RDA Data Fabric Conceptual model (see Data Fabric IG) focusing on the use of the Brokering pattern and its realization technology (see RDA Brokering IG) to move from the abstract to the implementation level.
Intermediation functionalities have been done for many years by the diverse Communities to support their applications: with the advent of the Web-as-a-Platform (WaaP), there is the need to make the functionalities in a more effective, automatic and re-usable way. In keeping with a PID Centic architecture, brokering services will contribute to move from a "Human-Controlled Process" to a "Type-Triggered Automatic Processing". While the applications potential can be widespread, even within communities, the greatest leverage comes in intermediation across communities.
Brokering scope can cover several aspects characterizing data management, processing, and sharing processes, including: mediation and harmonization taks for data discovery and access, data transformation tasks for workflow execution and information generation, and intermediation tasks for automating trading (i.e. contracts, usage, licenses, etc.) enabling Science to "trade" data with industry.
Intermediation Services Externalization presents several benefits (eg. costs, re-usability, flexibility, implementation of software and architectural patterns, such as: seperation-of-concerns pattern, information expert, low coupling, etc.) introducing some new challenges in areas such as services trust and governance.
Brokering/intermediation services can play an important role to enable the collaboration among RDA, EUDAT and LIBER.
