According to the last FRBR 2.0 draft,[1] the "expression" is the content of a work. It doesn't depend directly from the media it is possibly displayed on, but it cannot exist without the media, i.e. the text of a novel. The "manifestation", on the contrary, is the physical edition of a work. It is strictly connected to the media it is displayed on, i.e. the 1834 French edition of Dante Alighieri's Divina Commedia, printed in Paris by Éditeur Incertain.

It is possible that most of our properties may address the highest level, i.e. the work itself, but since we are going to have lots of items regarding specific editions (=manifestations) Note: I'm currently working at the Italian Institute for Libraries,[2] and among my tasks there is the "translation" of the UNIMARC-based data of the National Library Service[3] to FRBR, in order to finally export all those data into linked open data.
