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.
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.
The following statements refer to all methods and description given below:
Interface services give the programmer access to information about the current state of the REST interface.

Example: find help information through the interface

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:
