10. Development Issues
Generality vs Usability
• User interface is completely decoupled from the model
• Advantage: Annotation process is independent of the domain
model
• Drawback: lack of adaptation to end user

11. Development Issues

URI Design
• How it would be the best manner to identify concepts in the
Web of Linked Data?
• Should the user be concerned about the URI design?

12. Development Issues
Annotation tracking
• When the metadata should be persisted?
– On the moment of annotation
– Submitting the post
– An asynchronous update task
– On user demand
– On a later review process

13. Development Issues
Security and trustiness
• Security: Where the security mechanisms should be applied?
repository-side? or application-side?
• Trustiness: Publication workflow? or Annotation review
process?

14. Conclusions
• Enrich text-based and video information
contained in blog entries
• Full-independent of model domain and
slightly- from host system
• Issues about our Linked Data approach
• Need for raising the abstraction level in order
to improve usability
