[[File:Rest_gpmdb.png|center|GPMDB REST API v.1]]
 +
This document is a request for comment on a set of proposed new REST services for GPMDB. The RFC process began on June 11, 2012 and ended on September 10, 2012. This version (1.0) of the interface is complete and adopted.
 +
 
 +
These services are available to anyone involved in computational, biological or biomedical research. We, the providers, retain the right to block access by any user or system that we feel is using the information or infrastructure inappropriately.  
The purpose of the RFC is to define a set of straightforward [http://en.wikipedia.org/wiki/Representational_state_transfer REST (REpresentational State Transfer)] services to commonly required information based on the data in GPMDB. These services will provide simple, non-SQL methods to extract this information and make it available over the Internet to anyone wishing to use it as part of a network-aware application.

GPMDB REST API v.1

This document is a request for comment on a set of proposed new REST services for GPMDB. The RFC process began on June 11, 2012 and ended on September 10, 2012. This version (1.0) of the interface is complete and adopted.

These services are available to anyone involved in computational, biological or biomedical research. We, the providers, retain the right to block access by any user or system that we feel is using the information or infrastructure inappropriately.

The purpose of the RFC is to define a set of straightforward REST (REpresentational State Transfer) services to commonly required information based on the data in GPMDB. These services will provide simple, non-SQL methods to extract this information and make it available over the Internet to anyone wishing to use it as part of a network-aware application.

Contents

Conventions

The following statements refer to all methods and description given below:

  1. all GETs are made to the base URL "http://rest.thegpm.org/1";
  2. all protein and peptide sequences are expressed in single letter code;
  3. protein accession numbers use the same format as normally used in GPMDB; and
  4. all return values are in JSON notation (RFC 4627) as either an ARRAY or OBJECT.

/interface/ services

Interface services give the programmer access to information about the current state of the REST interface.

GET /interface/help => [ARRAY]

GET /interface/version => [ARRAY]

 input: none
return: [ARRAY - "string"] the version number of the REST interface

Example: find the current REST interface version number

Source code

These services are being implemented in PERL, the language that is used to provide most of the web page creation logic for the GPMDB system. The code is available at ftp://ftp.thegpm.org/repos/gpmdb_rest. The files currently available are as follows:

  1. rest.pl - provides an interface between Apache CGI calls and the database layer;
  2. gpmdb_rest.pl - a PERL module for most requests;
  3. gpm_rest.pl - a PERL module for "model" requests; and
  4. rest_client.pl - a demonstration command-line client that provides examples of how to use the services with PERL.
