Microsoft® Publisher document file format is used for creating various publication types such as newsletters, brochures, flyers, and postcards and is used in Emails and Websites. Pub files contain text as well as bitmap and vector graphics data.

Publisher Metadata is properties(information) that describe PUB documents. They are standard properties like publisher, title, last author, organization, URL, language, and other similar information.
