What is the difference between data and metadata?
3, Eric J. Miller. An Overview of the Dublin Core Data Model

It is important to learn XML for librarians, we have to not only figure out the traditional and machiedable catalogues, but also grasp some computer languages. It is interesting to learn Dublin Core.

The article for the database is very important reading to understand. Because I think we will need it during our LIS program. I have project to do this semester. The project deals with databases in my retrieving information class. I think we can understand them more when we work with actual project dealing with databases.
