D2.5 Object model and metadata: Open issues
This document summarizes open issues regarding the object model and metadata for Europeana. It discusses defining object types, relations between objects, and improving object descriptions. It also addresses the types of abstractions that will be received and needed from content providers, and how to represent access and license information. Real-world examples from the Europeana prototype illustrate these issues.
