3. DAS Distributed Annotation System

4. Problem Definition How the current DAS infrastructure can be extended in order to capture and use information provided for the users?

5. Proposed Solution DAS Writeback architecture

6. Proposed Solution Writeback protocol DAS 2.0 v.s. DAS1.53 Writeback New Format v.s. reuse DASGFF New model v.s. reuse MyDAS model Embedded Functions v.s. Uniform interface Small v.s.medium size database schema

7. Proposed Solution Server - MyDAS extension MyDAS Java DAS Servlet Generic server. The user develop the data source in a free way as soon as he implements the right interface Implements DAS 1.53 Extension Core extension for new commands Implementation of a writeback data source Database PostgreSQL Basic Authentication

8. Proposed Solution DAS clients

9. Proposed Solution Writeback client - Communication Proxy for the RESTful architecture DELETE PUT POST GET Authentication with the server JavaScript PHP J2EE

10. Proposed Solution Writeback client - Feature tabs a) Feature details b) Edit Feature details c) Delete Feature d) Feature History

11. Proposed Solution Writeback client - Snapshot

12. Future work On progress Writing the paper. MyDAS Writeback to 1.6 Outstanding: Non positional features Dasty3 + Writeback to 1.6 Future Ratings for user and features Implementation in other clients (Kariotype?)
