ConceptBase.cc is free software distributed under a FreeBSD-style license.

Download and install ConceptBase.cc Binaries

You can install ConceptBase.cc on Linux, Windows, and Mac OS-X. The Linux and Windows 10 versions use a local ConceptBase.cc server (CBserver). Older Windows and Mac OS-X versions use a public CBserver. To run the CBserver locally under Windows 10, you should first install the WSL Linux Sub-System. Otherwise, the Windows 10 version falls back to the public CBserver. You need a recent version of Java (Java 7 or later) to install and use the system! Install the 64bit variant of Java if your operating system runs in 64bit mode.

Latest stable version 8.2.20 from 2023-05-22

Read the ConceptBase.cc Copyright. Only proceed to the download step if you agree.
Download CBinstaller.jar from Sourceforge. It contains the latest ConceptBase.cc binaries plus the installation program.
Open a command window (terminal), change to the directory where you downloaded CBinstaller.jar.
Execute in the command window: java -jar CBinstaller.jar. Under Windows, you can also directly execute CBinstaller.jar from the web browser.
The CBinstaller window shall pop up. If the button "Install" is activated (green color), then just press it to install ConceptBase.cc. You can also adapt the installation directory before pressing "Install" but we recommend to use the default.

If the "Install" button is not activated, then Download/Select buttons are activated to download and select an installation archive. After download, you can continue with "Install".

Alternative download site

If the above download link fails, then download CBinstaller.jar from the CB-Forum. Some behavioral anti-virus tools could block CBinstaller from installing ConceptBase.cc on your computer. You need to temporarily disable these tools or install ConceptBase.cc manually as described in the installation guide.

Starting ConceptBase.cc

Linux, (Mac OS-X): Add the ConceptBase.cc installation directory to your search path, e.g.

export CB_HOME=$HOME/conceptbase
export PATH=$CB_HOME:$PATH

These two lines should also be added to your init file of your Unix shell, e.g. .bashrc if you are using bash. Start the ConceptBase.cc user interface CBIva via the command

cbiva

in a command window. It connects automatically to a local or public CBserver. You can also start the CBserver in another command window via the command 'cbserver [options]'. If your prefer to do so, then execute the 'cbserver' command before the starting CBIva. Consult the user manual for instructions on how to interact with the system. The tutorial on metamodeling is a good starting exercise as well.

Ubuntu 18.04: Ubuntu 18.04 does not come with the library libreadline.so.6. If you get corresponding error message when starting

cbserver -version

then you may try the following workaround:

locate libreadline.so.7
cd /lib/x86_64-linux-gnu
sudo ln -s libreadline.so.7 libreadline.so.6

Ubuntu 20.04: Ubuntu 20.04 also does not come with libreadline.so.6 and some other libraries. Execute the following commands to make is compatible with ConceptBase:

sudo apt-get update
sudo apt-get install libncursesw5
sudo apt-get install libncurses5
cd /lib/x86_64-linux-gnu
sudo ln -s libreadline.so.8 libreadline.so.6

Windows: Under Windows, you can start CBIva by double-clicking the file cbiva.bat in the installation directory c:\conceptbase. You can also use a Windows command window to start it. You may want to copy a shortcut to cbiva.bat to your desktop.

Mac OS: As with any other platform, the ConceptBase user interface runs fine under Mac OS if you have installed a recent Java runtime environment. You find the scripts cbiva, cbgraph and cbshell to start the user interface in the directory $HOME/conceptbase after installation. By default, the user interface connects to a public ConceptBase server on Mac OS. You can also use Docker to run the ConceptBase server locally on Mac OS, see the Conceptbase-Docker page of Kees Leune.

Raspberry Pi 2/3 under Raspbian: ConceptBase.cc runs fine on a Raspberry Pi 2, Pi 3 Model B, and Pi 3 Model B+ under Raspbian. You can download a Raspbian image preloaded with ConceptBase.cc from SourceForge. The README file contains instructions on creating an SD card from this image.

Configuring your desktop for ConceptBase.cc

You can configure your desktop to support the ConceptBase.cc file formats, in particular the graph file format '*.gel'. ConceptBase.cc graph files store the graph diagrams including layout information and all Telos sources (object definitions) belonging to the graph. Whenever you start-up a graph file, it will connect either to a local or public CBserver to provide you with the query and update capabilities of the CBserver. See here for details.
