  • quot; Zion! Hear Me!quot; Morpheus
  • ‘Zion! Hear me!’
  • quot; Zion! Hear Me! It is true what many of you have heard. The machines have gathered an army, and I speak that army is drawing nearer to our home. Believe me when I say we have a difficult time ahead of us. But if we are to be prepared for it, we must first shed our fear of it. I stand here before you now truthfully unafraid. Why? quot; Morpheus
  • quot; Because I believe something you do not? No? I stand here without fear because I remember. I remember that I am here not because of the path that lies before me, but because of the path that lies behind me. I remember that for 100 years we have fought these machines. I remember that 100 years they have sent their armies to destroy us.quot; Morpheus
  • quot; And after a century of war, I remember that which matters most: We are still here! Tonight, let us send a message to that army. Tonight, let us shake this cave. Tonight, let us tremble these halls of earth, steel and stone. Let us be heard from red core to black sky. Tonight, let us make them remember: This is zion and we are not afraid! quot; Morpheus

  • Resource Description Framework (RDF) • RDF is a universal format for data on the Web • RDF started as framework for metadata; providing interoperability between applications that exchange machine-understandable information on the Web.
  • Resource Description Framework (RDF) cont. • RDF emphasizes facilities to enable automated processing of Web resources and as such provides the basic building blocks for supporting the Semantic Web. • RDF metadata can be used in a variety of application areas; …
  • Metadata • Metadata is quot;data about data.quot; –ex. a library catalog is metadata. • The solution proposed here is to use metadata to describe the data contained on the Web. – Because of the volume of information the Web contains, it is not possible to manage it manually.

  • RDF Helps Make the Web More Functional quot; RDF has a general-purpose design and we are pleased that it is already being applied in areas we did not originally anticipate. Sophisticated applications of RDF may combine metadata about the same object supplied by more than one party on the Web, selecting the optimal source for specific properties and merging the sources' expertise. quot; -- Bob Schloss, IBM, W3C RDF Working Group co-chair

  • Starring • Tim Berners-Lee, W3C. – In 1989, he proposed a global hypertext project, to be known as the World Wide Web. Based on the earlier quot;Enquirequot; work, it was designed to allow people to work together by combining their knowledge in a web of hypertext documents. He wrote the first World Wide Web server, quot;httpdquot;, and the first client, quot;WorldWideWebquot; a what-you-see-is- what-you-get hypertext browser/editor which ran in the NeXTStep environment. This work was started in October 1990, and the program quot;WorldWideWebquot; first made available within CERN in December, and on the Internet at large in the summer of 1991.
  • The Semantic Web quot;The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.quot; -- Tim Berners-Lee, James Hendler, Ora Lassila, The Semantic Web, Scientific American, May 2001
  • The Semantic Web quot; The Semantic Web will bring structure to the meaningful content of Web pages, creating an environment where software agents roaming from page to page can readily carry out sophisticated tasks for users. Such an agent coming to the clinic's Web page will know not just that the page has keywords such as quot;treatment, medicine, physical, therapyquot; (as might be encoded today) quot;
  • The Semantic Web quot; … but also that Dr. Hartman works at this clinic on Mondays, Wednesdays and Fridays and that the script takes a date range in yyyy-mm-dd format and returns appointment times.quot; -- Tim Berners-Lee, James Hendler, Ora Lassila, The Semantic Web, Scientific American, May 2001
