Metadata is  data about data. Two types of metadata exist: structural metadata and descriptive metadata. Structural metadata is data about the containers of data. Descriptive metadata uses individual instances of application data or the data content.hile the metadata application is manyfold covering a large variety of fields, there are specialised and well-accepted models to specify types of metadata. Bretheron & Singley (1994) distinguish between two distinct classes: structural/control metadata and guide metadata.
Different meta tags are defined by changing the name attribute to a valid value. The most commonly used meta tag is the one used for descriptions: <meta name=description content=A general guide on the use of meta tags in html pages>. In cases of empty descriptions (or non-existent ones), search engines will generate a description from the content of the page. You can also set the author of a page using meta tags.
