A first GTM level 1 proposalISO has been working on creating a graphical notation for Topic Maps for some time now, and now the first proposal for level 1 has been published. (Level 1 is the ontology part; there is also a level 0, which is the instance part.) This is not a formal draft, just a simple slide show explaining the formalism, so it should be easy to read for anyone who's interested. This is the first step towards creating a standard, just coming up with something so people can say whether they like it or not. If the community approves it can be taken forward and a proper draft made; if the community does not approve a different proposal will have to be put together. ...

Let's say we want to create a topic for the city of Lviv, which is also known as Lvov. It has a few more names, but we'll pass over those for now. In his Master's Thesis Roy Lachica listed three different ways to do this, and we'll go through them one by one. ...

The idea with this blog entry is to write up some tips on this once and for all, in the hope that it can help people out there who struggle to write clean code. ...

The timing was really poor for me personally, unfortunately. We finalized the formalities of the acquisition of Ontopia by Bouvet two weeks before the conference, moved office the Friday before the conference, and then I spent most of the conference week discussing the acquisition with partners and customers. Then I had one week in the office, before leaving for three weeks of holiday in Japan. If you've been wondering why this blog has been quiet after posting #100, this is the reason. ...

There were two presentations, one on Compass, a Topic Maps search tool, and a case study of a Norwegian web site. ... Read | 2007-01-30 16:14 | 1 comment(s) Upcoming Topic Maps eventsThere are quite a few upcoming Topic Maps-related events here in Oslo, so I thought I'd do a summary of them. Firstly, there is a user's group meeting tomorrow (January 30th) on Topic Maps and semantic search. This meeting was so popular (at least 70 people signed up) that they've had to move it from the course room to the canteen. On February 27th there will be another user's group meeting on "Topic Maps and Web 2.0"; details on that will appear later, but you may want to pencil it in now. ... Read | 2007-01-29 13:26 | 1 comment(s) CTM: What is it, and why is it needed?ISO has been working on CTM (Compact Topic Maps syntax) for a while now, but very little has been published about it yet. I got a question about it by email, and decided to blog about it in case others were curious, too. ... Read | 2007-01-26 17:30 | 2 comment(s) Comparing Topic Maps and RDFThe Topic Maps and RDF technology stacks are quite complex, and it's not easy to see how the various pieces compare. So I thought I'd write a little bit about this. It was Trond's comment that triggered this, but I've seen no end of people struggle with this. I've written about this before, but I think it's possible to do a lot better. So, here goes. ... Read | 2007-01-06 18:52 | 6 comment(s) Published subjects and PSIsPeople often find the basic idea of published subjects quite clear and simple, but stumble over the detail, so I thought I'd write a little overview over the territory. The idea is to sketch out the basic concepts and how it all works. ... Read | 2007-01-04 15:25 | 1 comment(s) A new book on Topic MapsThose of you who have been waiting for a new Topic Maps book will be happy to hear that one has just been published. It was edited by Naito-san with the contributions of several Japanese people (Komachi-san, at last, but also others), if I read the cover correctly. And, yes, it was written in Japanese, so if, like me, you cannot read Japanese you'll have to settle for looking at the pictures. ... Read | 2007-01-01 20:15 | 2 comment(s) |
