Understanding Structural and Descriptive Metadata

This video tutorial introduces the concept of metadata, explaining it as data about data. It distinguishes between two types of metadata: descriptive, which provides details about individual pieces of information, and structural, which explains how data is organized. The video uses examples of photos to illustrate how metadata can vary and how it can be organized in tables for better understanding. It concludes by summarizing the differences between descriptive and structural metadata and their applications across various file types.

What is metadata often described as?

• Data about data

• Data about files

• Data about information

• Data about systems

Which type of metadata provides extra details about a specific piece of information?

• Organizational metadata

• Technical metadata

• Structural metadata

• Descriptive metadata

What does structural metadata help with?

• Identifying the creator of a file

• Recording the time a file was created

• Providing extra details about a file

• Describing how data is stored and related

In the photo examples, what type of metadata changed with each photo?

• Organizational metadata

• Structural metadata

• Descriptive metadata

• Technical metadata

What remained constant across all the photo examples?

• Descriptive metadata

• Organizational metadata

• Technical metadata

• Structural metadata

What is the purpose of structural metadata in a table?

• To provide extra details about each entry

• To identify the creator of the table

• To help understand the meaning of columns

• To record the time each entry was made

Which type of metadata would include information like the exposure time of a photo?

• Organizational metadata

• Technical metadata

• Descriptive metadata

• Structural metadata

What does structural metadata describe in a dataset?

• The meaning of fields and their relationships

• The creator of the dataset

• The size of the dataset

• The time the dataset was created

Which type of metadata helps in interpreting data by describing what fields mean?

• Structural metadata

• Organizational metadata

• Descriptive metadata

• Technical metadata

What is a key difference between descriptive and structural metadata?

• Both types of metadata change with each file

• Descriptive metadata is constant across files, while structural metadata changes

• Both types of metadata remain constant across files

• Descriptive metadata changes with each file, while structural metadata remains constant
