Semantic Web programmers to come together

By kjetilk. Friday, 26. January 2007, 20:29:35

The Semantic Web Education and Outreach Interest Group has published a small questionnaire with the intent of gather programmers around a few practical ideas, to create some applications that will make a real difference in people's lives.

The Semantic Web community has quite a few good programmers, and many have produced some cool demos of the technology. Also, many have been working on really big and advanced projects for years, and it is just starting to bear fruit. There has, however, been few times where we have gotten together with the goal of producing something useable quickly.

I wrote this questionnaire as a beginning to correcting the situation, as I believe it is important for the acceptance of the Semantic Web. My own, little pet proposal is also to use FOAF networks to ensure that emails from your friends will reach you even with aggressive spam filtering on. So make sure you continue to build those friend networks here on the Opera Community, it may help you in fighting spam soon!

Sorry, I broke some URIs

By kjetilk. Tuesday, 30. May 2006, 14:10:47

Since the launch of the Opera Community in September 2005, all members of the community has had an URI identifying them. Having URIs for everything is important, and even though you can't be retrieved over the network the URI is useful to identify you as a person.

Furthermore, we know that Cool URIs don't change, but I'm afraid I just changed them... :no: You see, the final, little part of the URI I gave you was very badly designed. It had a lot of unnecessary complexity, and with complexity comes bugs, and in fact, it turned out that some of them weren't even valid, since I hadn't taken into account that some usernames begin with a number.

It wasn't with a very light heart that I changed the URIs, but as I discussed this with other members of the FOAF community, it was clear that it was better to do it now, and deal with any problems that may occur with a process known as smushing, than dealing with the complexity that I had, especially as more people start using the URIs for real applications.

For most users, this change will not mean anything. The usual FOAF tools continue to work, it is only if someone has been indexing the URIs it will have any impact. I don't know if anyone has been doing that, but I would be interested in hearing about it! :sherlock:

UPDATE: I was a bit uneasy about this, so I found a way to at least attempt to unbreak most of the URIs, by using the sameAs property from OWL on those valid fragment identifiers from the previous version. That should give us the best of both worlds! :cool:

FOAFNaut Widget

I'd like to point out that Jim Ley, an SVG and Semantic Web guru, has created a widget called Widgnaut. It can be used to explore the social networks of the Opera Community, by clicking on people. It works similarly to FOAFNaut, by the same author.
