The articles in this section are for partners who use YouTube’s Content ID matching system. You upload content to the content management system to create assets, with each asset representing the rights embodied in a copyrighted work, such as a sound recording, music video, or composition. Videos that contain copyrighted works are then linked to each asset by a claim that asserts ownership on the content within the video. The claim links a video to a particular asset and applies a policy(monetize, block, track) specified by the asset owner(s).
