JSpace
JSpace is a tool for exploring complex information spaces in ways that make sense for people. It is a 100% pure Java application which draws inspiration from mSpace and is capable of using mSpace model files combined with RDF datasources to provide users with a column-based view of their information space.
JSpace provides all of the power of mSpace along with some of our own innovations, including new Information Panel views and multi-select in a column.
Webstarts
This is the initial release of the latest version of jSpace, v.40. A lot of work has gone into this new release. We kept the UI, but replaced much of the underlying code. As a result, jSpace allows for a more flexible browsing experience. You can now move the goal column around, you are no longer restricted to having it as the right-most column. You can even close the goal column altogether and browse other parts of your dataset. There is also now support for switching your goal column on the fly. We also added better support for handling Literal values in columns, and some preliminary support for bNodes. So please, give the new version a whirl and let us know what you think!

Demos
Before you start, some of the demo’s are run by loading the specified configuration file into the jSpace client. To do this, first run the v.40 webstart linked above. Once jSpace is running, go to “File->Load from Config…” and select the config file you wish to load. This configuration file will point jSpace at the appropriate database and model file for the demo. Once its loaded, you will be asked if you want to set the current model and data source to the ones specified in the configuration file, you’ll want to hit “Yes.” Then the demo will load up into jSpace and you’re ready to browse!
Conference Data
An aggregate of the ISWC and ESWC 2007 demos listed below with new data from OWLED 2007 browseable via a single model.
ClinicalTrials.gov
This demo is based on a dump from http://clinicaltrials.gov. We got an XML dump of their data and converted it to RDF using a simple XSL script. This converted a few thousand records into about 150k triples.
ISWC
A demo using the ISWC conference data for ISWC 2007. Download the configuration file linked below and load using the above instructions. For those interested, you can view the model file
ESWC
A small example using the ESWC conference data about attendees and the papers submitted to the conference.
CIA World Fact Book
The CIA World Fact Book dataset scraped into RDF and browsable via jSpace!
Baseball
A demo of the latest jSpace, the previously unreleased v.41, with a database containing a dump from baseball-databank.org’s extensive baseball statistics. We’re big baseball fans around here, so combining the browsing power of jSpace with as large and interesting a dataset as found on retrosheet really goes a long to show off what jSpace can do. We’ve also included in this release some improvements to the jSpace environment; for columns containing typed literals, you can perform type specific operations on them. So, in the case of the baseball stats, is very easy to restrict your results to people who have hit more than 300 homeruns, or who made their MLB debut between June 2000 and September 2004. You can also view relevant material on the web using the new web view component in the Information Panel. We think changes like these have really improved the power and flexibility of jSpace.
