"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 that only the Registry at parts.mit.edu is registered with the DASDY service 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
