Some subjective feelings :
. The schema.org microdata that we expose are poor, but as poor as many 
OAI-PMH records that populate many repositories.
. The schema.org microdata can talk about several entities, which is not 
possible with OAI-PMH.
. As we have decided to use the 'itemid' attribute, we hope that these 
microdata will join a Web of interlinked data, and not only a Google 
silo of juxtaposed data.
. Adding metadata to an HTML page is often a frustrating experience, 
whether you've chosen microdata or RDFa : too many compromises between 
the expressivity of metadata and the simplicity of HTML code.
. The uncertainty about the peaceful coexistence of the schema.org 
vocabulary and other vocabularies is a real problem.
. All the limitations you encounter with microdata (and even RDfa) are 
balanced by the freedom to design metadata as you want in separate RDF 
pages.

Voila :)
