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.

Google Chrome

Yesterday Google launched their new Google Chrome web browser. The follow-up in miscellaneous media has been enormous. I’ve tested it myself and I do find it a very interesting application. There are a few features I miss, but I guess Opera has made me a demanding web user. All in all I expect Google to release a solid and innovating new browser when the final version is finished. As usual regarding Google, a few questions concerning the content and other privacy issues do surface. The new secure surfing feature is great, but a few people have issues with the licensing terms:

"By submitting, posting or displaying the content you give Google a perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute any content which you submit, post or display on or through, the services. This license is for the sole purpose of enabling Google to display, distribute and promote the services and may be revoked for certain services as defined in the additional terms of those services."

That is a direct quote from this article at Slashdot. I am not sure this is an issue to fear. It seems that they need that in order to display content on your screen, but we will see I guess.

Finally, if you have not seen the comic from Google explaining the new browser, please read it.

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.

Please read the original article in The New York Times.

Microsoft vs Google

Google has their Google Apps. Now Microsoft has opened up their Microsoft Office Live Spaces. It’s their attempt at utilising MS Office and giving the public the tools for collaboration and sharing that Google Apps has been able to provide. I am looking forward to see what this leads to.

Wish for 2008

When you read the news from anti-virus companies and security advisors you get convinced that 90% of the software you find on the net is malware, and the last 10% have so many security issues that it turns out the same thing. At the same time a life seems to be worth less than the copyright interests of media companies.

I don’t know if you have noticed, but I feel that the whole world has been overrun by solutions and programs that want to harvest personal information about me. The products that don’t ask for the information grab it anyway.

Trusted computing is a much debated architecture, maybe rightfully so. That kind of architecture might limit the spreading of free/open source software. Microsoft has proven that they can offer this trough their HD-Video support. There they have signed code in all layers, and only approved hardware devices are allowed in the pipe from storage media to screen. I am not saying that it is impossible to bypass this pipe in some way, but the threshold to perform such a hack has been raised a fair bit.

So, when you consider the stack of components needed to display HD-Video, what do you need to have the same security/quality for our computers? Especially when you are connected to the Internet?

The question then is if we maybe should take a look at this “cursed” subject again. Financing solutions in order to secure that open source software can be verified and approved might become a reality. There is one thing that we have learned so far. It is impossible to count all evil. You cannot permit the execution of all software except the bad ones listed in a list. Such a list will never be complete. But you can allow all enumerated good software and block the execution of all other code. Anti-virus software tries to perform this enumeration on our behalf, but still they do not know everything and ask the users what to do when in doubt. When they do, the s**t hits the fan. Users do not know what to do. They do not realize the consequences of their choices.

Again, the driver is the money. It is somewhat of a symptom of the state of the world that it’s more important for Microsoft that a video is not copied than to secure the personal information of a user. If somebody steals all our personal details, all our money from our bank accounts and our identity, that is not as important for Microsoft as a video unlawfully duplicated and distributed.

So what is my wish for 2008?

My wish is that our lives and our identities will become more important to protect on the net than the economic interests of a few.
