And, in fact, you know, this ‘Web2.0’, it means using the standards which have been produced by all these people working on Web1.0.” - Tim Berners Lee • Web2.0 is about creating new web-based services and applications using (practically) identical technologies as those that were put in place at the birth of the Web

Various Discovery Fellows make contributions including Robert C. Koons, J.P. Moreland, William Lane Craig, and William Dembski. &lt;br /&gt; &lt;br /&gt;Koons begins by noting that there is a simple correlation between existence and the requirement of some non-natural first cause. He observes an irony that science thinks it requires naturalism, when our very ability to practice science, due to the orderly, reliable, and predictable behavior of the universe implies a non-natural intelligent cause. Scientific dependence upon naturalism is self-refuting. &lt;br /&gt; &lt;br /&gt;Moreland's quotes Plato to reveal that there really is nothing new under the sun: scholars have been debating naturalism for millennia, and naturalists have been ever pugnacious in their insistence that mutual co-existence is not an option. Moreland recounts that the great philosopher wrote in Sophist: &lt;br /&gt; &lt;br /&gt;"They [naturalists] define reality as the same thing as body, and as soon as one of the opposite party asserts that anything without a body is real, they are utterly contemptuous and will not listen to another word. ... On this issue an interminable battle is always going on between the two camps." &lt;br /&gt; &lt;br /&gt;Yet the battle may eventually be over if the cosmological data presented by William Lane Craig has anything to do with it. Craig recounts the history of cosmology from when where scholars celebrated an eternal universe with no beginning or end, to one where the universe either has a "supernatural cause" or "one must say that the universe simply sprang into being out of nothing" (Big Bang cosmology mandates an expanding universe that is finite in both space and time.). Craig recounts the words of one team of scientists: "The problem of the origin [of the universe] involves a certain metaphysical aspect which may be either appealing or revolting." &lt;br /&gt; &lt;br /&gt;WilliamDembski closes the volume by arguing that naturalism is no more supported by the scientific data in biology than it is supported in cosmology. Irreducible complexity in nature disallows the possibility that life arose via naturalistic mechanisms. It also signifies an intelligent cause that scientists cannot deny any longer. </Content></Review> ….. </CustomerReviews> </item> </Items></ItemLookupResponse>

  22. Integrate Web2.0 in portal • Synchronous/asynchronous Web2.0 services • AJAX: “Asynchronous JavaScript and XML” • Each Web2.0 service comes with its own API • API Request • (XML) Response • Process of data mashup • Portal sends HTTP request to Web2.0 service, including some metadata of the object • Some (simple) XML is sent back from the Web2.0 service to the portal • The portal analyzes the XML and presents the information in an “ergonomic” way

  24. Contextual Web2.0 services • Portal is in full control of which Web2.0 services are delivered to end user. This does not necessarily correspond to what the end user wants: • Against the idea of Web2.0 (« power to the people ») • Someexamples: • Holdings & availability: view holdings of my library • Tagging: create and view tags from a specific disciplinary KB • Social bookmarking: on specific platforms • Institution policy favors Facebook • Group of experts use specific platform for peer-to-peer communication • Desire to “social bookmark” on same platform, irrespective of which portal used • Comments, reviews: language dependent • Portal specific • EgBICTel: show biography of director of ethesis
