11. Issues
 Global environment
 Multilingual environment
 Multi-domain environment
 Archives, libraries, museums, … mappings!
 Importance of branding (license, namespace)
 Who said that?
 Assessment of quality in a multi-voice environment
 Trust
 Importance of “authority” “control”
 = Identity/Identifier management
 Local vs global authorities (URIs)
 “Record” is the old paradigm
 Linked “statement” is the new
 We all need to help each other (not alone any more)
 We are all in this together, and so is our data
