Registration is the act or process of entering information about something or somebody in a bookkeeping or other record-keeping application. Most music organisations maintain a register or registry: a list of members, information files on rightsholders, or music sheets available for study or borrowing in a library. As music is distributed and documented increasingly online, musicians and their groups and associations must fill out registrations for various digital services almost every day. The amount of registered data becomes daunting and terrifying, and maintaining all these data is very tiring. As a result, the registers contain a lot of outdated data, and we see increasing illegal activities by private registry holders to find data about music entities in other systems and copy it without permission or supervision. With our innovation we would like to show how music organisation can reduce this burden, harmonise their registration processes, and create more useful and up-to-date registers.
