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

Generality vs Usability
Iván Ruiz-Rube
URI Design
Development Issues
• 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?

Development Issues
• 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 4th Metadata and Semantics Research

Annotation tracking
Iván Ruiz-Rube
Development Issues
• Security: Where the security mechanisms should be applied? repository-side? or application-side?
• Trustiness: Publication workflow? or Annotation review process?

Security and trustiness
Iván Ruiz-Rube
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
