Online Demo

The online demo of Collaborative Protégé can be launched either by Java Web Start, as an applet, or using a Protégé client. It is recommended that you use the Java Web Start launcher or the Protégé client. In case you have difficulties with the Java Web Start, please try the Applet demo.


Run Demo using Java Web Start (recommended)

You can start the online demo with Java Web Start by clicking one of the following links:

If Java is not already installed on the client machine, it will point you to the download and install website of Java 5. After the install, please try to launch again the Protégé online demo by clicking on the button from above.
If you have problems launching the demo with Java Web Start, please use the Applet demo.


Run Demo using a Protégé client

You can connect using a Protégé client (desktop application) directly to the server. It is very important that the Protégé client has the same version as the Protégé server.

The current Protégé version running on the server is: Protege 3.4 beta 128.

Please download the above Protégé build from the Protégé download site.

To connect to the server, start Protégé, go to the File menu -> Open and then click on the Server button. In the server panel, type in the Host machine name: smi-protege.stanford.edu:5200, then fill in your user name and password and click OK to connect.


Quick users guide

We developed the Collaborative Protégé as an extension of the existing Multi-user Protégé system. The multi-user system is a client-server version of Protégé, which allows multiple clients to connect to a Protégé server and to browse and edit simultaneously the same ontology. All the changes done by one client are seen immediately by all the other clients.

The server used for this online demonstration is : smi-protege.stanford.edu:5200


Connecting to the server

After you have clicked on the button from above, you will get the following login window (left image from below):

Please do not change the default value of the Host Machine Name text field. The correct value for this demo is smi-protege.stanford.edu:5200.

If you already have a user name and a password, please enter them in the corresponding fields in the Connect to remote host window (left image from above) and press the OK button.

Registering a new user

If you are a new user, please click on the Register new user button in the Connect to Remote Host window. This will pop-up a new window (right image from above). Fill in the fields and click OK. If the user name already exists, you will get a warning message and will be asked to enter a different user name. After successfully creating an account, the new user name and password will be automatically filled-in in the Connect to remote Host window. Please click again on OK to proceed to the next step.

Connecting to a project

After successfully logging in to the Protégé server, you will see a window that allows you to select from the available projects on the server.
Please select the CKC2007 project from the list and click OK.
