Frederick Giasson has written a tutorial article on using the semantic web to integrate data and make new use of data found on the web using semantic web technologies and approaches.

He shows the steps needed to create working applications, from data transformation to user interface. At the end, there is a working example that is available online.

This means that data only matters. In fact, the only thing one need now is to build a good data source. Once the data source is well built (remember, the data source can be anything here, from a search engine database to the products catalogue of a company, or even the personal web page of a 14 years old geek).

From that data source, everything can be generated for each web page (URL). If the content requested is a HTML page, then the data source can generate XML, run a XSLT skin template with and then send a HTML page: just like any other web page. However, from the same data source, a semantic web crawler could request the RDF/N3 data for the same URL. Then the DDWP would send the RDF/N3 representation of the URL.

So from one data source, you can get its data the way you want.

From that point a URL (or a web page, call it the way you want) become a presentation page web, a web service, etc; All-in-one!

The dude behind Wired said in some interview I happened to see, that the culture is stretching out. Still, the big ones get 80% of the market, this won't change, but the remaining 20% get split over a far bigger area and are increasingly important. I think he called it "the far end" or "the end of the curve", whatever its called: Important is the fact that we are moving to microcultures.

When I visit a friend, we listen to a radio station only airing electro remixes of C64 songs, which you can receive on the net. See, its the dude from Kaiserslautern who enjoys electro remixes of C64 songs who is the market of tomorrow.

You will instantly see what I mean here and get a feeling for whats happening by watching it happen: I googled for videos on the nintendo WII and all I found was microculture:


So what do you do when you get hands on a WII controller and a DJ software? Nothing, if you are like me, but if you are DJ shift-1 and take your thing serious, you go for it. You remix it, you make a video out of it, you invest a few days of video editing and you happen to have a gig at bootiesf.com in may....

There is one thing in this for my own satisfaction: when I was dancing on any techno event years ago, I longed for this experience of controlling the music by dancing. So I am looking forward to the time this hits the markets and we have youths on festivals remixing and dancing their own music... not so far away, or? If it ever happens, drag me out of my adult life and force me to join it, perhaps I will be too conservative to dig it.

Next is a video demonstration of using a WII controller on a windows computer to play Halflife two:


At the same moment, the authors refers to a wiki of the www.wiili.org developer hangout and an IRC channel on freenode.net about wiili, and doesn't forget to mention that the music we hear is from his DJ friend djsbx.com who happens to publish his trance/house music freely on the internet.

These dudes are good in what they do, they do the right thing in the right way, respect. The second video shows how this guy connects to his peers using a wiki and an IRC chat, and that he gives credit to the guy doing the music. All is done by namedropping a few web addresses. I like this. Its not much effort, it doesn't take many people or money to do it, but it reaches out.

After playing the good old Netrunner game from time to time, but not often enough, I want to pass it on. Netrunner is a trading card game designed by Richard Garfield, the creator of Magic: The Gathering. It is full of insider gags from classic cyberpunk (Neuromancer, etc). Words like "Wilson" or "Chiba" will trigger the right synapses. One player is the evil corporation trying to make big money, the other is a witty hacker trying to steal information from the company by breaking into their network.



My favorite card is "Fortress Architects" because of its text:
"You want us to build that? Not even God has the money to afford that!"

"You're working for Saburo Arasaka, not God."

Ok, I will keep my favorite cards and enough for two players to gamble from time to time, but I sell the the worthy rare cards (and the others) on ebay. If you are interested in one or the other card or more, buy them. All revenue made goes into a good cause: I want to buy a Nintendo WII.

During practical RDF projects, one big challenge is always how to choose good URIs for your resources. The RDF standards say very little about this topic. There are some best practices and helpful recommendations, but they are scattered all over the web. Creating "cool URIs for the semantic web" is hard.

Richard Cyganiak, Max Völkel and myself have written an article about how to choose cool URIs, filled with practical knowledge and background information about the problem and solutions. We have collected what we have learned during projects such as Semantic MediaWiki, dbpedia, D2R Server, Gnowsis, and Nepomuk. We hope that this article is a help for you or your students to get started programming Semantic Web applications.

Abstract
The Resource Description Framework RDF allows you to describe web documents and resources from the real world—people, organisations, things—in a computer-processable way. Publishing such descriptions on the web creates the semantic web. URIs are very important as the link between RDF and the web. This article presents guidelines for their effective use. We discuss two strategies, called 303 URIs and hash URIs. We give pointers to several web sites that use these solutions, and briefly discuss why several other proposals have problems.
