Linda Sile et al. have published "Towards More Consistent, Transparent, and Multi-Purpose National Bibliographic Databases for Research Output" in the LSE Impact Blog.
Here's an excerpt:
Even though the various national databases differ in terms of implementation and organisation, the challenges faced are rather similar. These range from specific technical tasks such as record deduplication, to more theoretical debates on principles that should guide the work with national bibliographic databases. However, perhaps the most pertinent issue is the need for reliable (persistent) identifiers for all research information entities. Author identifiers, research organisation identifiers, digital object identifiers – all of these could, in the long run, establish a more stable research information environment where different datasets can be integrated across institutional, regional, and even national contexts.
