• the Species Product Discovery service which is the main service realizing the facility;
• the Species Product Discovery Client Library which is a client library allowing user to interact with the Species Product Discovery Service;
• the Species Product Discovery Objects which describes the objects stemming from the Species Product Discovery service;
• the Darwin Core Terms which is a quick guide providing a list of all current Darwin Core terms used by the SPD service;
• the Species Product Discovery TestSuite which is a java library for testing and checking of the functionality offered by a Species Discovery plugin.
