DAS services to retire

EMBL-EBI's DAS services are to retire

DAS services to retire

19 Aug 2014 - 08:07

20 August 2014 - EMBL-EBI will be decommissioning a number of Distributed Annotation System (DAS) web services over the next 18 months, and will retire all DAS services by the end of 2015. Many EMBL-EBI resources have introduced or are actively developing alternative data integration technologies, and currently offer dedicated REST services.

Since its inception during the Human Genome Project, DAS has fulfilled a valuable role in integrating distributed and varied data, particularly for display in the Ensembl genome browser and other applications that feature data visualisation. Unfortunately, the level of usage of EMBL-EBI's DAS services can no longer justify indefinite support and maintenance. Some services have already been retired, and others will be decommissioned as their relevant hardware expires.

Affected services

  • Most data sources on the EMBL-EBI ProServer gateway have been shut down, including:

    The remainder will follow over the coming months. Data will be archived until the end of 2015.

  • Ensembl DAS client and server functionality will run until the end of 2015. Ensembl recommend TrackHubs as an alternative for integrating genomic data, and will be further developing TrackHubs to include protein data in the near future.

  • The UniProt DAS server, which includes the protein reference server, will run until the end of 2015. It is possible to obtain most of the information provided by the UniProt DAS server, via the uniprot.org REST API. UniProt are also currently developing a set of new REST API services that could be used in the future to obtain aggregate or specialised protein information.

  • Dasty will continue until the end of 2015. In future, similar functionality could be developed using a combination of protein TrackHubs, BioJS and REST APIs.

  • InterPro will continue to run its DAS server until the end of 2015.

  • Pfam recently moved to EMBL-EBI from the Wellcome Trust Sanger Institute. The Pfam DAS sources will not be transferred from the Sanger DAS server to EMBL-EBI.

  • The Sanger Institute has confirmed that it will continue to run the DAS Registry's programmatic services until the end of 2014. The associated graphical user interface may shut down earlier.
