[GeoNetwork-users] Sentinel data- SAFE Scheme insertion in GeoNetwork

Dear all,
has anyone tried to add ESA/GMES SAFE Schema into Geonetwork? If yes, how
was your experinece and where did you find a Scheme file to inseert?
because I have tried with a few schemas that I found online but Geonetwork
is not able to aaccept these Zip files.
Any suggestion or anything?
Regards,
Luis
