Reading Notes on Reading for Unit 4:

Database:

The database is extremely important when it comes to libraries since it is what it uses to store its digital information. Libraries need a way to translate it analog content, particularly catalog, into digital content making it more accessible to patrons. There are different types of architecture to databases particularly one type that is row oriented or another architecture that is column oriented. Of particular interest to librarians are database management systems, the software that organizes and stores the days. Librarians should consult with their people who are in control of their IT to decide which system is best for them.

Introduction to Metadata:

A concept that has become more important over the years is Metadata which is information about information. Metadata is of greater importance because the library has more information then ever available to its patrons in a digital format. In order for this digital information to be accessed in an efficient way there has to be information about the data that makes it easier to search. The most common use of metadata in libraries are found in MARC record, these are cataloging records that are able to be read but computers which are used with their digital card catalogs. The others type of Metadata deal with value, content, and format.

Overview of the Dublin Core Data Model:

A huge problem with Metadata is the fact that Metadata formats are no the same across the world. Metadata is even formatted differently across disciplines. This is where the Dublin Core Data model comes into play, its intention to come up with a consensus about metadata. Since there is not one true way to describe information across different cultures the Dublin Core Data Model tries to identify common features that would help in its goal.

  1. I liked the information on metadata because I was able to easily understand it because of working with the MARC records at the PCI. It helped everything make sense to me, like I'm sure it did with you too.

    I also like your description of the Dublin Course Data Model. It is very tight and makes a lot of sense when put that way.
