I just went through the ODF 1.2 spec part regarding metadata, I think we 
should reset all the meta data defined in the spec except "meta:user-defined"… 
And remember to fill in the meta:template with the XLink to the source 
template.
If nobody disagrees nor sees anything hazardous in it, I'll implement that.
