[GeoNetwork-users] ISO 19139 maintainer contact

Hi all,
I'm no metadata expert, so please feel free to correct me.
When I'm filling out the metadata with the portal editor using the vector
template, in the "Advanced view", "Maintenance" tab I have there "Metadata
author" instad of a sort of "Maintainer Contact". Is it a bug or am I
mistaken? I'm with the 2.2 stable.
Thanks in advance,
Karel
