  The Smart4Health (S4H) software application will empower EU citizens to
manage, analyze, and exchange their aggregated electronic health data. In order
to provide such a service, basic features are needed to ensure usability,
reliability, and trust. The CEF building blocks implement such functionalities
while complying with EU regulations. This report examines the current status
and applicability of the CEF building blocks for the envisioned S4H software
application. The major findings of the report are that (1) most CEF building
blocks are currently not ready to be applied without further implementation
efforts and (2) the S4H-specific use cases and user needs, to which the single
CEF building blocks correspond, must be clarified. Open questions raised in
this report need to be answered before a clear analysis can be made. Moreover,
the functionalities of CEF building blocks aim at the matured product, while
for the first version of the S4H software application basic implementations
suffice. Still, concepts need to be elaborated of how the sample implementation
of CEF building blocks or suitable alternative applications can be included
into the system at a later point.
