Archives of mediateques, theatres, music schools, conservatories, universities, etc., are the most important sources of cultural heritage. Such institutions are interested in digitizing content to (i) improve the service towards their attendees, thus increasing the number of collections provided, (ii) add new functionalities to the service already provided, (iii) save fragile materials otherwise settled to time deterioration, such as tapes, disks, documents, etc. Publishers are interested in digitizing only content that guarantees a certain return of investment and at the same time they are inclined to limit the distribution of the content located in archives, so as to control its exploitation and to preserve the content ownership. WEDELMUSIC has been defined to allow content providers to share and distribute interactive music in the respect of the owner's rights. This means that networks of content sharing Mediateques can arise while respecting the owner's rights. Consequently, solutions, models and tools were defined and developed, including adequate protection and monitoring solutions.
