WSDbfetch allows you to retrieve entries from various up-to-date biological databases using entry identifiers or accession numbers. This is equivalent to the CGI based dbfetch service. Like the CGI service a request can return a maximum of 200 entries.

For more information see:

• dbfetch web interface
• dbfetch REST service

Web services registry entries:

  • WSDbfetch (REST)
  • WSDbfetch (document/literal SOAP)
  • WSDfetch (RPC/encoded SOAP)
• CoWS: Search result

Sample clients are provided for a number of programming languages. For details of how to use these clients, download the client and run the program without any arguments.

For further details see WSDbfetch Clients.

In addition to these sample clients users have submitted workflows using these services to the myExperiment workflow repository. See workflows using the WSDbfetch Web Services for a list.

There are three interfaces to the WSDbfetch (SOAP) service, each with its own WSDL:

1. WSDBFetchDoclitServerService (document/literal): http://www.ebi.ac.uk/ws/services/WSDbfetchDoclit?wsdl
   Recommended for development of new clients. For compatible SOAP tool-kits WSDLs with additional semantic annotations (using SAWSDL) are available:
   • Annotated using EDAM: http://www.ebi.ac.uk/ws/services/WSDbfetchDoclit?sawsdl
   • Annotated using OBIws: http://mango.ctegd.uga.edu/jkissingLab/SWS/Wsannotation/resources/WSDbfetch.sawsdl. Provided by the Kissinger Research Group, University of Georgia.
2. WSDBFetchServerService (RPC/encoded): http://www.ebi.ac.uk/ws/services/WSDbfetch?wsdl
   Provided for compatibility with SOAP tool-kits which support only RPC/encoded SOAP services and for use by older clients.
3. WSDBFetchServerLegacyService (RPC/encoded): http://www.ebi.ac.uk/ws/services/urn:Dbfetch?wsdl
   Deprecated provided solely for compatibility with old clients, please do not use for new development.

Fetch a set of entries in a defined format and style.

Arguments:

• db: the name of the database to obtain the entries from. For example: “uniprotkb”

Generic exception used for errors thrown by the WSDbfetch service.

Subclasses:

• DbfParamsException
• DbfConnException
• DbfNoEntryFoundException

Exception indicating that the input parameters failed to validate. The message contains specific information about the cause. For example:

• uk.ac.ebi.jdbfetch.exceptions.DbfParamsException: Database, wibble , not found!

• uk.ac.ebi.jdbfetch.exceptions.DbfParamsException: No database found for the job:
  Job: 
          Database name: wibble
          Style: raw
          Format: default
          IDs:    blah
  

Parent class: DbfException

Exception indicating that there was a problem contacting the database to retrieve the requested data. For example:

uk.ac.ebi.jdbfetch.exceptions.DbfConnException: Unexpected error when opening stream on the URL, please contact support@ebi.ac.uk

Parent class: DbfException

Exception indicating that no entries were found in the database which matches the request. For example:

uk.ac.ebi.jdbfetch.exceptions.DbfNoEntryFoundException: No result found

Common causes of the error include:

• Invalid identifier used for the specified database. For example: EMBL-Bank does not contain entries with RefSeq identifiers (e.g. XM_002123246).
• Use of an identifier which is not supported for the specified database. For example: the EMBL-Bank query used by WSDbfetch does not support sequence versions (e.g. L12345.1) instead the accession (e.g. L12345) should be used, or the archive database EMBL-SVA, which does support sequence versions, should be queried.

Parent class: DbfException

Exception indicating that required parameters were not specified, or were in an incorrect format. For example:

• uk.ac.ebi.jdbfetch.ws.wsdbfetch.InputException: The 'query' argument doesn't contain ':'. Proper format= DBNAME:ID

• uk.ac.ebi.jdbfetch.ws.wsdbfetch.InputException: No database found in the query

• uk.ac.ebi.jdbfetch.ws.wsdbfetch.InputException: No ID found in the query
