single blogger. The purpose of a professional
blog is to promote the individual, not a

• A tag is a non-hierarchical keyword or
term assigned to a piece of information (such as

• A metadata helps describe an item and allows it
to be found again by browsing or searching.
• Tags are generally chosen informally and
personally by the item's creator or by its viewer,
depending on the system.

15. Mashup
• A mashup, is a web page, or web application,
that uses content from more than one source
to create a single new service displayed in a
single graphical interface.
• For example, you could combine the
addresses and photographs of your library
branches with a Google map to create a map
mashup.
