Metadata
Metadata tags are used to help describe a document. There are two different types of
metadata: http-equiv and non http-equiv. Metadata that is http-equiv is used to
determine metadata to be used as HTTP header data.
There are two metadata methods in the document:
getMetaData(): This is used to retrieve the document metadata.
setMetaData(): This is used to add metadata to the document.
When we create extensions that handle information that we want search engines to
index, it is important to add metadata to the document.
