Hi Jean-Pierre,

we are definitely working on a tool to map with a number of existing
formats. Note also that all the concrete implementations we have so far go
this route, and the browser scenario proposed by Silvia does that too. The
"new" properties are no new vocabulary, but just a means to make clear what
the smallest common nominator between existing formats is.

Best,

Felix
