Upcoming Ontopia events

The upcoming Topic Maps 2010 conference in Oslo on April 14-15 will feature a number of Ontopia-related presentations. There is a full-day Ontopia tutorial during the tutorial day, and also a half-day tutorial on using Ontopia with Ruby on Rails. There are also a number of Ontopia-related presentations during the conference itself.

The week before there will also be a meeting about Ontopia held by the Norwegian Java User’s Group in Grimstad, in southern Norway, on April 7th.

Triggers

While presenting tolog updates at TMRA 2009 I casually referred to the possibility of using tolog updates to create a trigger mechanism in Ontopia similar to triggers in relational databases. After the presentation the idea grew on me, and so I decided to elaborate a little further on it and present it in the open space session. The result was this little presentation, which gives a brief outline of the idea.
