Apple,
I use Aperture and it has a larger/better metadata feature/benefit than Photos does. When or IF are you going to add Copyright Notices to Photos for the users of Aperture can migrate to Photos.
Mac mini, OS X Yosemite (10.10.3), I7, 16GB

Use the photo editing extensions to add watermarks or metadata.
The External Editors extension lets you call many different photo editors. With Watermarker you can add watermarks to your photos.
None of these solutions is as elegant as Aperture's handling of metadata. Photos is far from being a professional photo management system, like Aperture is and probably never will be. If you need a professional tool consider to migrate to Lightroom or Capture One, for example.
