DAS workshop - 2010

DASDistributed Annotation System

Problem Definition

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

QuickTime™ and a decompressor

are needed to see this picture.

Proposed Solution DAS Writeback architecture

Proposed SolutionWriteback protocol

DAS 2.0 v.s. DAS1.53 WritebackNew Format v.s. reuse DASGFFNew model v.s. reuse MyDAS modelEmbedded Functions v.s. Uniform

interfaceSmall v.s.medium size database schema

Proposed SolutionServer - 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

Proposed Solution DAS clients

Proposed Solution Writeback client - Communication

Proxy for the RESTful architecture DELETE PUT POST GET

Authentication with the server JavaScript <=> PHP <=> J2EE

Proposed Solution

Writeback client - Feature tabs

a) Feature details

b) Edit Feature details

c) Delete Feature

d) Feature History

Proposed Solution Writeback client - Snapshot

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?)
