SOME CLICKS AFTERThe user can access the “curated and reliable” cluster of editions
of Don Quijote de la Mancha in Italian

SOME ISSUES
• Pure FRBR representation not always possibledct:subject, dct:language at Manifestation level instead of Work level
• Around 30% of bibliographic records still not connected to their Expression
• Manifestations are mostly described with strings, not many links
• Does the modelling seem to complex to people outside the library community?
