This part discusses the basic content of bibliography, such as the objectives and entities. Nothing to comment on.

MARC and Dubline Core
The content is helpful and interesting.
One question: In Dubline Core, two different people may create quite different descriptions of the same resource. How to reach uniformity in Dubline Core? In MARC age, many small libraries who lack catalogers often download the original MARC data which is created in large libraries by catalogers. Could we share Dubline Core data like MARC?
What is the main difference between Dubline Core, TeX and Refer? Can they reach the requirements of interoperability in digital libraries?

I have read this essay before in LIS 2600. It is very useful. I am confused when I read this essay at the first time, but now I could understand the most parts since we have learned metadata.

This essay is a personal reflection on the development of Dubline Core.
In my opinion, it will take a long time for a unified metadata to replace MARC. Maybe Dubline Core is just a transfer metadata.
