IPI (Interested party information) is a unique identifying number assigned by the CISAC database to each Interested Party in collective rights management. It is used worldwide by more than 120 countries and three million right holders.
Two type of IPI-numbers exist:
The IP Name Number is the code for a name or pseudonym related to an entity (natural person or a legal entity). One entity can have several names. Prince for example has the IPI-codes 00045620792 (Nelson Prince Rogers), 00052210040 (Prince) and 00334284961 (Nelson Prince R).
 The IPI Name Number is composed of eleven numeric digits.
The IPI Base Number is the code for a natural person or a legal entity. It has the pattern H-NNNNNNNNN-C.
For example Pablo Picasso has the IP Base Number I-001068130-6.
IPI codes are connected with International Standard Musical Work Codes (ISWC). For example, one of the songs called Ernie, which has an ISWC number of T-010.171.314-7, has just one interested party, that of Benny Hill whose IPI number is 00014107338. This IPI number can then be used to find all other works by him.
In relation to ISWC each party has at least one role. Roles can be:
The standards describe the person who adapts music as an arranger, and the person who adapts the text of a musical work to be an adapter.
Eve Online is a player-driven, persistent-world massively multiplayer online role-playing game (MMORPG) set in a science fiction space setting, developed and published by CCP Games. Characters pilot customizable ships through a galaxy of 7,800 star systems. Most star systems are connected to one or more other star systems by means of stargates. The star systems can contain moons, planets, stations, wormholes, asteroid belts and complexes.
Players of Eve Online can participate in a number of in-game professions and activities, including mining, piracy, manufacturing, trading, exploration, and combat (both player versus environment and player versus player). The character advancement system is based upon passively training skills in real time, even while not logged into the game. The game's open-ended sandbox-like design allows players to set their own goals without the need to follow pre-defined missions.The game's developer CCP Games continuously adds expansions free of charge that change game mechanics and add features. Since the game's release in 2003 the expansions have added gameplay elements such as more ship classes and advanced missions for players to master.
