Microformats are simple, open data formats built upon existing and widely adopted standards. They are designed for humans first and machines second. Common microformat types include hCard for contact information, hCalendar for calendars and events, and hReview for reviews, ratings and opinions. Microformats can be used on webpages to embed contact, calendar, and review information for users and search engines to extract.
5. What are Microformats?
Designed for humans first and
machines second, microformats are
a set of simple, open data formats
built upon existing and widely
adopted standards.
6. The Semantic Web
The Semantic Web is not a separate Web but an extension of
the current one, in which information is given well-defined
meaning, better enabling computers and people to work in
cooperation.
It is a source to retrieve information from the web(using the
web spiders from RDF files) and access the data through
Semantic Web Agents or Semantic Web Services. Simply
Semantic Web is data about data or metadata.
