Some thoughts on identityThe concept of identity is at the heart of both Topic Maps and RDF, and consequently it has been much discussed over the last few years, but I've seen very little writing on what identity itself actually is. This posting offers some thoughts on that. ...

I was going to post some cards and letters, and this being just before Christmas there was quite a queue. I spotted a computer in the office that was obviously set up for customers to use, and started fiddling around with it. ...

The actual list of differences can be found in the standard itself, but the standard says nothing about why they were made, and so I thought I would give a quick overview of that here. ...

This posting is just a simple walk-through of the syntax with examples. People have also asked for an explanation of the differences with version 1.0, and I'll do a separate posting on that later when time allows. ...

I was reading a local IT newspaper in the office kitchen, waiting for my tea water to boil, when I spotted an ad for Ibas. Ibas is a Norwegian company specializing in data recovery. I mostly associate them with really spectacular recovery operations after fires and shipwrecks, and so on. However, the ad said they also did this for private individuals who had lost their digital photos. ...

I'll try to clear up the confusion in this blog posting, as best I can. ...

The meeting started the Friday after the conference, and continued for three days, finishing on Sunday. ...

He has done a study where they built a Topic Maps-based portal to Korean folk music (known as Pansouri) with a quite detailed ontology of the domain. They then compared how easy it was for 20 test subjects to find information in the traditional portal and the new Topic Maps-based one. 10 subjects used the traditional one first, then the Topic Maps one afterwards, and the remaining 10 did it the other way around. They tested both objective measures (how many steps to find information on 6 assigned search tasks), and subjective measures (how did the test subjects feel about the portals). ... Read | 2006-10-12 09:09 | 4 comment(s) TMRA 2006 — day 1Like last year, I will try to do a semi-live blog report from the TMRA 2006 conference on Topic Maps in Leipzig. This year the conference is in the Campus Villa Ida, which was finished just two weeks ago. TMRA is actually the first conference that is held in this shiny new conference center. (So far everything seems to be working smoothly. This is, after all, Germany.) ... Read | 2006-10-11 09:20 | 2 comment(s) |
