DAS Writeback

We designed and developed a Collaborative Annotation System for protein sequence information called DAS Writeback, which extends the Distributed Annotation System (DAS) to provide the functionalities of adding, editing and deleting annotations.

The solution consists of an extension of the DAS protocol that defines the communication rules between the client and the writeback server following the Uniform Interface of the RESTful architecture. A protocol extension was proposed to the DAS community and implementations of both server and client were created in order to have a fully functional system. For the development of the server, writing functionalities were added to MyDAS, which is a widely used DAS server. The writeback client is an extended version of the web-based protein client Dasty3, which can be used in its instance at http://www.ebi.ac.uk/dasty/.

A tutorial to install and execute the main commands of the Writeback data source can be found here.

The live installation of the writeback for the protein coordinate system is in http://www.ebi.ac.uk/enfin-srv/wb-srv/das/writeback.
