Abstract:

Microformats is a term used to describe the storage of information using simple markup variations within existing markup languages. To a certain extent, microformats describes a methodology or philosophy, and comprises a set of design principles. Microformats is not a new language. It is usually a permutation of XHTML. The philosophy of microformats involves storing data in human-readable formats which are also machine-readable, but the emphasis is on the humans! Information tends to be visible, rather than hidden metadata.
