Descriptive metadata is information that describes the content of a resource. It is the "aboutness" of the content. For example, the name of something is often descriptive, such as "tiger". If I asked you to tell me more about the tiger, you might say that "it has stripes, has 4 legs and a tail, and lots of teeth". That would be more descriptive metadata.
When generating descriptive metadata, we make use of controlled vocabularies, including content in our local MADS database.
