Some Lessons Learned

• Unicode
• Mostly OK for our goal but not perfect
• User Environment (Browsers and Fonts)
• Versioning Issue
• What is version?
• e.g., Japanese translation version 1.0 of
  Reference Description of DC Element Set version
  1.1
• How can we cope with elements/qualifiers proposed
  by local communities?

Summary

• Multilingual metadata schema registry is crucial
  for information exchange and metadata
  interoperability in the global community.
• ULIS DCML registry provides reference
  descriptions of DC elements and qualifiers in
  multiple languages
• Application profiles, guidelines to create
  metadata are important components for the
  registry but not yet provided.
• a number of problems for future research
