"The distributed annotation system (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." - Wikipedia

The DAS interface to the Registry can provide sequence and feature information about any part in the Registry.

DAS information is available via the HTTP protocol. (NOTE: the DAS interface is only operating on parts.mit.edu at this time.)

DAS DSN Server

http://parts.mit.edu/das/dsn

• parts.mit.edu is a valid DAS server it will return the XML for the list of DAS services available on the server.

DAS Protein Annotation Server

http://parts.mit.edu/protein_annotations/entry_points

• A list of protein coding sequence parts that have swissprot numbers and can be understood by the DAS system.

http://parts.mit.edu/protein_annotations/types

• A list of the types that are valid for protein_annotations

http://parts.mit.edu/das/protein_annotations/features?selection=UniprotNumber

• Identification that the sequence exists

http://parts.mit.edu/das/protein_annotations/dna?selection=PartName:firstbase,lastbase

• Returns XML containing the sequence for the given part from the firstbase to the last base specified

DAS Parts Server

http://parts.mit.edu/das/parts/entry_points

• Returns an XML list of all available parts in the registry. The information includes the part name and sequence length.

http://parts.mit.edu/das/parts/features?segment=PartName:firstbase,lastbase

• Returns easy to read XML listing each feature in the part between firstbase and lastbase.

http://parts.mit.edu/das/dna?segment=PartName:firstbase,lastbase

• Returns the easy to read XML listing of the sequence for the part
