The document discusses projects, standards, and implementations to support the European Higher Education Area (EHEA). It addresses three areas: 1) international visibility through the PLOTEUS portal, 2) standards such as the Metadata for Learning Opportunities (MLO) for describing courses, and 3) best practices shared by the Rome Student System Standard Group (RS3G) implementers network. The goal is to facilitate student mobility and lifelong learning through common standards and exchange of data between different university systems.
