First of all a big thank to Thomas.
I took the fontinfo file in the Example Fonts Folder (specifically the AGaramond Pro one). There is a lot of information there that i dont know if it is needed for OT creation. Particularly, AscenderHeight, LcHeight, FigureHeight, DescenderDepth, etc. and all the overshoots for these values.
I know that all this information can be obtain from the BlueValue entry in the private dictionary, but is all this information really needed if, in fact, you can find it there?
And, if all these information is needed can you tell me where i can find the fontinfo file specification?
