Visualisation of Topic Maps (the attempt of a summary)

Hi everybody, thanks for all your kind answers in my last ("Auto-Generating TMs out of rel. DB") thread. I was unable to check my e-mails for the last couple of days and on top of that, they are on another computer, so i´ll answer the questions raised in my other thread about Auto-Generating TM´s out of relational Databases in the next days (depending when i can access my other computer). Sorry for that. Now, as the other thread lost it´s way somehow and was skipping to the aspect of the "Visualization Of Topic Maps", i wanted to open a thread where we might gather information about different Visualiztation technics/APIs for Topic Maps and so forth. As this seems to be a topic, which not only I am really interested in. Maybe we can also keep an eye on the usability of the generated graphs, when handling large topic maps. I will work with the Touchgraph and maybe Hypergraph renderes in the next time and can write my opinions on this, when i have finished. Open Source Visualizations i know of at the moment (keep in mind that i´m no pro when it comes down to TMs, so this is just what i think of them, any idea, criticism is highly appreciated): -------------- Touch Graph: -------------- http://touchgraph.sourceforge.net/ KNOWN IMPLEMENTATIONS: There are a number of different implementations around (see link), i don´t know how far these are based onto Topic Maps. For topic maps there is the Java Stand Alone Application TMNav (http://tm4j.org/tmnav.html), which relies onto the TM4J framework (http://tm4j.org/), which is providing an implementation of the TouchGraph for browsing Topic Maps DEVELOPMENT STATUS: It looks like the project is mostly dead, judging from the last release on sourceforge from the end of 2002 POTENTIAL: imho it´s good at browsing TopicMaps as it is interactive. For a bigger example of this one can have a look at the Google Browser implmeneted with Touchgraph: http://www.touchgraph.com/TGGoogleBrowser.html, it has good options to parameterize the graph in a way you want it to look DOWNSIDE: Not really developed any further, don´t know how good it scales on big graphs with lot´s of topics, looks like no good documentation is available, development mostly based onto extracting the knowledge from the source files -------------- HyperGraph: -------------- http://hypergraph.sourceforge.net/ KNOWN IMPLEMENTATIONS: There are a number of different implementations around (see link), i don´t know how far these are based onto Topic Maps. For topic maps there is the Java Stand Alone Application TMNav (http://tm4j.org/tmnav.html), which relies onto the TM4J framework (http://tm4j.org/), which is providing an implementation of the HyperGraph for browsing Topic Maps DEVELOPMENT STATUS: It looks like the project is still running, the last release on sourceforge is from the end of 2004 POTENTIAL: good at browsing large TopicMaps, because of hyperbolic visualization DOWNSIDE: i don´t know how good you can parameterize the graph for your own needs -------------- Prefuse -------------- http://prefuse.sourceforge.net/ KNOWN IMPLEMENTATIONS: A couple of implementations are on the website (see link), i don´t know how far these are based onto Topic Maps. DEVELOPMENT STATUS: The project is up and running, with the latest release from April 2005 POTENTIAL: looks like lot´s of different visualization options are possible, the project aim is to develop highly interactive visualisations. I don´t know whether there is something similar to TouchGraph or HyperGraph already out there. DOWNSIDE: i don´t know how much programming effort it takes to visualize a Topic Map in a similar vein TouchGraph or Hypergraph does -------------- Jung -------------- http://jung.sourceforge.net/ KNOWN IMPLEMENTATIONS: A couple of implementations are on the website (see link), i don´t know how far these are based onto Topic Maps. DEVELOPMENT STATUS: The project is up and running, with the latest release from April 2005 POTENTIAL: looks like lot´s of different visualization options are possible, i am not sure whether one can configure this visualisation to make it "browsable" like HyperGraph or TouchGraph or whehter this is more or less "static". DOWNSIDE: i don´t know how much programming effort it takes to visualize a Topic Map in a similar vein TouchGraph or Hypergraph does Maybe you are interested to share your opinions on Graph visualization, or know of further Visualization techics. I´d love to hear what you have to say about this topic.

RE: Visualisation of Topic Maps (the attempt of a summary)

Hi Murray, you´re right, "dead" is the wrong word and i really can´t tell whether TouchGraph is not in development any longer. I´ve seen it being used at various applications and so it seems to be really common. I was just thinking that it might be useful to incorporate the date of the last "offical" version into the summary and my overhasty labeling as dead is definitely wrong. Personally i think of TouchGaph being really good, that´s why I am trying to develop with it. And for sure, I wish Alex Shapiro all the best for his future work with touchgraph.
