Are D. Gulbrandsen announced an upcoming meeting discussing Ontopia case studies and future development.
Just want to make sure that everybody knows that the Topic Maps group
within The Norwegian Computer Society organize a meeting about Ontopia
and the Open Source process tuesday 25 aug. The language will be
Norwegian, but I'm sure some of the people taking part will blog about
this in english.
We will have two very interesting Ontopia case-studies (killer apps?)Read more
It wasn't that long ago I reported that topicmap.com had moved across to WordPress as its blogging and content management platform. WordPress proved to be quite an easy system to set up and configure with lots of great themes and plugins. I was pretty happy with the way things turned out, however, was less less than enthused with some of the organisational aspects of the site. The use of taxonomy and categories could only get you so far, providing for the application of facets to posts.Read more
Subj3ct is a Subject Identity Resolution Service, it provides both a portal for humans to use and an API for developers and applications. We store subject identifiers, equivalent identifiers and also links to web resources that contain structured or unstructured information about a subject.
Robert Barta has done something very cool with a topic map of his for mapreduce. He has used the TM as a source to go out onto the web and to build up a corpus from which terms are extracted and their semantic distances are calculated. These are then plotted onto a relief map where altitude is represented by the distance from the most popular term, "web". The result is quite a funky looking visualization where like terms are grouped by the topography as well as proximity.Read more
Lars Marius Garshol has announced the release Ontopia 5.0.0, the first version in its open source incarnation.
The Ontopia project has just released the first version of the open source Topic Maps toolkit Ontopia, earlier known as the Ontopia Knowledge Suite. This release is based on OKS 4.1.0, but has seen a number of new features and bug fixes.
Congratulations to all involved.
I have been working my way through the "identity crisis" on the web, trying to get my head around how I can get a system to work with both RDF and TMs. In a nutshell I'm interested in creating XTM and RDF feeds out of a CMS which will have some knowledge subject indicators. I'm expecting users to use a lookup service (Sindice or similar) or manually enter URLs to equate subjects in the system (tags, categories, pages, posts) with public subjects outside (wikipedia, PSI repositories, linked data). What will be the identity of these URIs though? I don't want to dwell on the pros and cons of the various solutions. I'm mainly interested in how I can pick URIs which will work in both systems. Maybe you can help.Read more
The Simile timeline widget has been incorporated into the site so that it is now possible to see a timeline of 10 years of topic maps history. I've included all news, resources, tools and organisations. It can a bit crowded, especially around conference times but for the most part it works pretty well. Some of the dates are a bit dodgy - in many cases I just had to guess a year and set it to Jan 1. If you have any changes please let me know.Read more
I have configured the WP2TM WordPress plugin to include subject identifiers for each of the tags which have an entry in Wikipedia. This should help with any efforts to link the data in the xtm feed. There still are a lot of gaps though! I might go back and fill in the vendors and other popular tags another day.
Update: The XTM feed is no longer available since the move to Drupal. However, most entities have an identifier now. MW 20090728
Johannes Schmidt has just updated QuaaxTM core which now implements PHPTMAPI 2.0. The SVN is now available including a test suite.
