W3C direct mapping

[Giovanni Bartolomeo <giovanni.bartolomeo@uniroma2.it>]

Hello,

W3C has recently proposed two recommendations ("direct mapping" and  
"R2RML") to map database entries into URIs (better URIRefs). link:  
http://www.w3.org/2001/sw/rdb2rdf/

"In the direct mapping of a database the [URIrefs] directly reflects  
the names of database schema elements, and neither structure nor  
target vocabulary can be changed. [...] With R2RML on the other hand,  
a mapping author can define highly customized views over the  
relational data."

Since the sintax in the direct mapping is quite similar, but not the  
same, to the one used in ODAta, wouldn't it be good to spend some  
effort trying to harmonize the two?

Best Regards,
Giovanni
