Abstract [en]
JASS is a JAVA Application that allows to create and analyse networks as used in space syntax. It is intended for convex space analysis and allows for import of raster image files (jpg, tif) to draw networks and then calculate a set of measures (e.g. Real Relative Assymetry, Connectivity, Mean Depth), and to convert graphs into justified graphs. It also allows exporting graphs to SVG files.

Note
Notes on functionality
The zip-file contains two versions of JASS. One is located in the “old” folder. Both have the same functionality but saved files are incompatible between versions. The reason to provide both versions is that the “Load background” function is different; on MacOS Catalina (2020) it seems to work on the version in the “old” folder, whereas on other systems it is the other version that works.
Please note that you may need to create small files and try different file formats for background images. Please also consider downloading the JAVA compatibility package for old JAVA apps. JASS is quite old by now.

On background and creation of the software
This JAVA Application was developed in 2003 as part of a research project leading to the publication “Spatial systems as producers of meaning: the idea of knowledge in three public libraries”, and produced in cooperation with a group of students in computer science at a course given by NADA – a now-defunct department shared by KTH and Stockholm University. The JASS tool was specified and programmed in close cooperation between researcher and students, to produce as good and user-friendly a program as possible to be used in the research. It was also written with a GNU General Public License.
The students who wrote the code (also named in “about” in the help menu) are:
Lena Bergsten, Tommy Färnqvist, Patrik Georgii-Hemming, Per Grandien, Christer Olofsson, Mikael Silfver, Erik Sjöstedt, Fredrik Stavfors, Marko Tokic
Unfortunately, the webpage containing the software download and source-code has been taken down by NADA, hence the app being made available here. If I can find the source code and/or additional source material I will add supplemental downloads.
