Semantic Web Layer Cake

David Norheim and his semantic cake

David Norheim is getting one year older on Saturday (2009.03.14), and WWW is twenty today (2009.03.13)

On Saturday 14 March 2009 David Norheim can celebrate another birthday. Today the WWW can celebrate it’s twentieth birthday. One of the creative girls (Terese Liadal) at work created this cake and we felt we just had to share it with all the rest of you out there in cyberspace as well.

David Norheim is one of the leading Semantic Web gurus in Norway and was extremely happy when he got this cake. The cake illustrates one version of the Semantic Web Layer Cake, an illustration that describes the different layers in the architecture stack. There are several versions of this layer cake available online.

The future, 2.0

As a follow up to my earlier fantasy of new possibilities regarding a documented generation I would like to blow out some steam regarding social software as well.

One of the problems we see today is that there are only a few people producing the information that is consumed by all the rest. Those reading are participating with tagging, bookmarking and rating of the content, but even this should be easier. The production of the content could also be easier.

So let us play with the idea of a documented world. On our way forward we have a few stops on the way. Some of them we are experiencing right now, among else by using Facebook, Linked-In, Plaxo or other social networking applications. By blogging and micro-blogging what we do and what interests us we are giving the world knowledge and information that can be used by other applications as what we often call value-added content.

Consider this, you are watching a video or listening to a podcast on the net regarding some information. The video or audio is tagged in such a way that as you play the content, different meta-information rolls by in tandem with the content, and the media player might then display related information based on automated searches as you watch. We are talking hypermedia that intelligently can give you information that you need or want. You will be able to decide where the information is gathered from.

In the next generation of social software I expect us to be able to increase the value for each other in even better and easier ways than today. And as always, the enabler of these features will always be technology.

So in the future, expect great things. Probably not some of the small ideas I present to you here. What we will see will probably be better.

And you will be a part of it. By easily producing content, and adding meta-information and grading what you see. The world will give you more of what you want and of what interests you.

Whether it is semantic technology or intelligent search engines, I bid welcome to interesting and feature rich social networks, in a documented world where you can have an even more enhanced life experience.

Soon, in a life near you!

The Web Time Forgot

The New York Times has this very good article on early ideas of the world wide web. "The Web Time Forgot" describes the how a Belgian called Paul Otlet tried to index all known knowledge, and realised that this was too hard to do by paper alone. So in 1934 he dreamt up this concept of doing this with "electric telescopes". That is an electric device that would allow people to search and browse through millions of interlinked documents, images, audio and video files. According to NYT he described how people would use the devices to send messages to one another, share files and even collaborate or congregate in online social networks.

This proto-Web relied on a patchwork of analog index-card and telegraph machines, but it included an idea of a hyperlinked structure of information.

“This was a Steampunk version of hypertext,” said Kevin Kelly, former editor of Wired, who is writing a book about the future of technology.

I personally liked this little nugget.

…Otlet’s version of hypertext held a few important advantages over today’s Web. For one thing, he saw a smarter kind of hyperlink. Whereas links on the Web today serve as a kind of mute bond between documents, Otlet envisioned links that carried meaning by, for example, annotating if particular documents agreed or disagreed with each other.

The article goes one to discuss Semantic Web in a not so nice way. I admit that I don’t agree with the author on that account, but all in all an interesting read.
