In light of lessons learned during the DAS/1 implementation, a transition to a more flexible and powerful protocol called DAS/2 is underway. This transition will occur slowly and DAS software will continue to support DAS/1 for some years to come. The evolution from DAS/1 to DAS/2 is very much a community-driven process, informed by a variety of [[RFCs]] (Requests for Comment) received from the user communty.

[[DAS/2]] is the latest version of the DAS specification and builds on the capabilities of the original [[DAS/1]] spec. See the [[DAS/2]] page for more information.

DAS/2 development officially commenced in July 2004 when a 2-year NIH grant was funded. Participating in the DAS/2 grant are Affymetrix, Cold Spring Harbor Lab, the European Bioinformatics Institute/Sanger Center, and Dalke Scientific.

Welcome To BioDAS.org

http://biodas.org/ will eventually be migrated to a wiki format. In the meantime, please continue to use the original site. If you want to pitch in and help this migration, send a note to the BioDAS discussion list.

About DAS

The Distributed Annotation System (DAS) defines a communication protocol used to exchange biological annotations. It is motivated by the idea that annotations should not be provided by single centralized databases, but instead be spread over multiple sites. Data distribution, performed by DAS servers, is separated from visualization, which is done by DAS clients.

DAS is a client-server system in which a single client integrates information from multiple servers. It allows a single machine to gather up genome annotation information from multiple distant web sites, collate the information, and display it to the user in a single view. Little coordination is needed among the various information providers.

DAS is heavily used in the genome bioinformatics community. Over the last years we have also seen growing acceptance in the protein sequence and structure communities.


What can I do with DAS ?

A number of sites and applications is available that are using DAS.

The Protocol

Currently there are two versions of the DAS protocol

DAS/1

DAS/1 is the original version of the specification written by Lincoln Stein and Robin Dowell and is the basis for a number of existing clients and servers. More than 200 DAS/1 servers are currently running worldwide including WormBase, FlyBase, Ensembl, TIGR, UCSC, and UniProt. For a listing of all available DAS sources please proceed to http://www.dasregistry.org

DAS/2

DAS/2 is the latest version of the DAS specification and builds on the capabilities of the original DAS/1 spec. See the DAS/2 page for more information.

Mailing Lists

There are currently two separate mailing lists for public discussions about DAS, one for DAS/1 and one for DAS/2. See the BioDAS mailing list page for more info.
