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

Conference

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
