This proof-of-concept is one of the output of the SLHS "Swiss health metadata repository: implementation recommendations" Policy Brief. It mainly helped to showcase the richer browsing capabilities available with a graph-based structure of the metadata. This proof-of-concept allowed to retrieve feedback from the various SLHS stakeholders in order to further iterate on a metadata repository. For time limitations and its explorative nature, all the proof-of-concepts’s technical aspects can be largely improved. For further details please refer to the "Swiss health metadata repository: implementation recommendations" Policy Brief available on the SLHS website (www.slhs.ch).
