I'm looking for an evaluation method for digital libraries, particularly, I need to measure the capabilities of any digital library taking into account the technological, conceptual and policies dimensions of the digital library.
I mean digital libraries in general. I have to evaluate the current state of digital libraries in my country, taking into account several dimensions such as technological (interoperability, access, metadata quality, services, etc) and procedures. For that, I'm looking for others evaluation frameworks or similar evaluation studies.
