The DAS Registry^{V2.8.5 02 09 2010}

The Biological Distributed Annotation System Registry- Search (New Interface)

DAS registry help - capabilities

A DAS capability is a particular DAS command that can be understood by a DAS source. These commands are being defined by the DAS specification (version 1.5) and by the alignment & structure DAS extension (version 1.1)

The DAS registration server ensures that the DAS sources "speak" the correct DAS language. It validates all DAS sources every two hours to ensure they are still available.

The following DAS capabilities are supported: To retrieve reference objects to which annotations are attached:

• sequence - retrieve a sequence
• structure - retrieve a structure
• entry_points - get the entry points of a DAS source

to retrieve annotations

• features - get the annotations for a reference object
• types - get the available types of annotation of a DAS source

to provide the relationship (alignment/mapping) between two objects, which can be in different coordinate systems:

• alignment - get the mapping of one object (in a particular coordinate system) onto another

for visualization:

• stylesheet - defines how the feautres should be drawn in the visualization client

Other DAS extensions:

• interaction - share protein-protein interaction data.

We are currently in the process of adding support for all extensions of the latest spec.
