COSOMA admit members on bases of individual, group or through rights holder associations. To be admitted as a member, the applicant must be a creator whose work (for example music, book, poem, etc.) has been fixed in tangible material e.g. if you are a musician, the songs must be recorded in for example, cassette, CD or DVD. Members declare ownership of rights in the works and deposit copies of such works which aid in determining beneficiaries of royalties that may accrue from exploitation by different users.
