Metadata is data about data, and it plays a very significant role in the way we understand the world around us. Granted, our textbook for LIMS 5320 is a book, but it is not the same kind of book as a cookbook or Patricia Polacco's children's book, Pink and Say. By providing us with information, that is, organized data, metadata increases our understanding of objects, and it enables us to save time, as we are relieved of the burden of searching through huge amounts of information that we may not need.

Granularity is the fineness with which data in particular fields is sub-divided. This breakdown is evident in MARC records as information about a particular object—book or DVD—is more extensive than what we see on the front of a book—title, author and sometimes publisher. Information can go from before 1XX, the creator of the object, to beyond 7XX, added entries about it. Note the examples of low and high granularity with my school’s address:
Low granularity:
1. address: 3244 W. Ainslie St. Chicago , IL 60625 USA
High granularity:
1. street address: 3244 W. Ainslie St.
2. city: Chicago
3. postal code: IL 60625
4. country: USA
Higher granularity:
1. street: W. Ainslie St.
2. address: 3244
3. city: Chicago
4. state: IL
5. postal code: 60625
6. country: USA
