            http://en.wikipedia.org/wiki/Wiki
                   A wiki is a page or collection of Web pages designed to enable
                    anyone who accesses it to contribute or modify content, using a
                    simplified markup language.[1][2] Wikis are often used to create
                    collaborative websites and to power community websites.
                   WikiWikiWeb (http://c2.com/cgi/wiki) was the first site to
                    be called a wiki. Ward Cunningham started developing
                    WikiWikiWeb in 1994,
Wiki principles
Digital Enterprise Research Institute                                       www.deri.ie




            A wiki is an informational resource, like a reference
             manual, encyclopedia, or handbook
                   The most famous is Wikipedia, a highly used, online, free-
                    access encyclopedia
            It consists in a group of web pages that allows
             users to add content and also allows others to edit
             the content:
                   It relies on cooperation, checks and balances of its
                    members, and a belief in sharing of ideas
                   Contrary to weblogs, wikis focus on community agreement
                    rather than on personal views of a topic
                   This creates a community effort in resource and
                    information management, disseminating the 'voice'
                    amongst many instead of concentrating it upon few

Wiki editing and auto-regulation
Digital Enterprise Research Institute                                              www.deri.ie




            In a Wiki, anyone can edit exiting content, create
             new pages, and delete existing content
                   WikiWords are used to create new pages and a simple
                    syntax allows to write pages without HTML
                   A versioning mechanism allows to browse and retrieve
                    older versions to avoid vandalism (+IP blacklisting,
                    protecting some pages, etc.)
            Auto-regulation
                   People voluntary maintain the wiki to avoid vandalism
                   Let’s try !
                      –  Choose a Wikipedia page regarding a topic that you like
                      –  Edit the page and add a personal comment
                      –  Let’s come back in a few minutes ...

             networking components, this is not their main
             purpose
                   You can use them only to publish / discover data

Digital Enterprise Research Institute                                                www.deri.ie




            How to let people browse my social data from a
             single entry point
                   Social aggregators can help, Eg: FriendFeed
                   We will see in a next lecture how the Semantic Web can
                    provide alternatives, but thanks to open standards and
                    process
            Privacy issues
                   What do you want to publish ?
                   Who can access it ?
                      –  Do you really want your lecturer to see your latest party
                         pictures from Facebook ?
                   Work still must be done in that direction !
Other Web 2.0 services
Digital Enterprise Research Institute                                       www.deri.ie




            Blogs, wikis, OSN and media sharing are the most
             popular form of Social Media websites
            But many other services are available on the Web
                   Videoblogging, Podcasting ...
            In addition, mash-ups allow to combine data from
             various Web 2.0 services to create your own
                   Most of the Web 2.0 service provide an API to access their
                    data
                     –  http://programmableweb.com
                   Eg: Display upcoming concerts on a GoogleMap
                     –  Topic of a future lectures
Licensing issues
Digital Enterprise Research Institute                                         www.deri.ie




            When you publish content online, you may allow
             people to reuse it, but you want to keep some kind
             of ownership
                   So that your work can be recognized
                   Licensing does not unallow to give your work ‘for free’
                      –  E.g.: Free-source software licenses (GPL ...)
            Creative Commons - http://creativecommons.org
                   Share, Remix, Reuse — Legally
                   Decide what people can do with your content:
                      –  6 different contracts
                   Some bands put their songs using a CC-licence
                      –  http://jamendo.com

Digital Enterprise Research Institute                                     www.deri.ie




            “Web 2.0” is not far from the initial idea of the Web
                   “The idea was that anybody who used the web would have
                    a space where they could write and so the first browser
                    was an editor, it was a writer as well as a reader. Every
                    person who used the web had the ability to write
                    something. [...] When you write a blog, you don't write
                    complicated hypertext, you just write text, so I'm very,
                    very happy to see that now it's gone in the direction of
                    becoming more of a creative medium” - Tim Berners-Lee -
                    Interview with the BBC (2005) -
                    http://news.bbc.co.uk/1/hi/technology/4132752.stm

            We’ll see in a next lecture that the Social Semantic
             Web is even more near from the initial vision of the
             Web !
Assignment
Digital Enterprise Research Institute                                     www.deri.ie




            Choose a particular project / interest that you have
            Describe and implement your Social Media strategy
             to promote it to a worldwide audience !
                 Define and argue which tools you will use (blogs, OSN ...)
                 Then create some account(s) and publish content ... keep
                  it alive if you can, and you might be able to create a
                  community around it !
                 Finally, provide a single entry point so that people can
                  discover all your Social Media regarding to that topic
                  content from a single entry point
                      –  Using your Drupal website

Digital Enterprise Research Institute www.deri.ie   “Web 2.0” is not far from the initial idea of the Web   “The idea was that anybody who used the web would have a space where they could write and so the first browser was an editor, it was a writer as well as a reader. Every person who used the web had the ability to write something. [...] When you write a blog, you don't write complicated hypertext, you just write text, so I'm very, very happy to see that now it's gone in the direction of becoming more of a creative medium” - Tim Berners-Lee - Interview with the BBC (2005) - http://news.bbc.co.uk/1/hi/technology/4132752.stm   We’ll see in a next lecture that the Social Semantic Web is even more near from the initial vision of the Web !
