Why would libraries and users benefit from copyright metadata schema now? 
nCopyright controls “copying” and “copies” of creative expression
nEvery use in digital environment creates a “copy”
nEvery use potentially implicated or controlled by copyright
nLibraries throughout time mission provide long-term access and use of collections
nCopyright metadata schema designed to support use and uses of digital information
In the digital environment, ever act of access or viewing is a “copyright event” (terminology of Michael Carroll of Creative Commons), so copyright has become even more important than ever.
