According to an Italian colleague of mine, the OpenDocument Format (ODF) is now officially a standard in Italy. It is included now within the catalog of standards as well as on an official information page.
Toward the end of the latter document it says:
Il formato OpenDocument, date le sue caratteristiche, conferir� maggiore efficienza e flessibilit� alla comunicazione tra pubblica amministrazione e cittadini.
which says that ODF will confer major efficiency and flexibility in the communication between the public administration and the citizens. Bravo!
