Re: [protege-user] Saving ontographs constructed with instances and classes

Hi Jean-Louis,

UI means User Interface (what you see on the screen and buttons you click) which is opposed to the application business logic (main functionality behind the UI). Bugs in the business logic usually very serious as they can disrupt everything. Bugs in the UI, while being annoying, are less serious and frequently neglected. Java UI is notoriously known as a habitat of bugs because usually it is not properly designed. Programming UI requires careful consideration of many threads, running concurrently. Those threads handle events which usually are organised in queues (software engineering structures), what you see in the error messages.

Protégé currently is not actively maintained. OntoGraf is a plugin developed by other people. It may also be not actively maintained now. Bugs might reside in the main Protégé code and/or in OntoGraf.

Cheers,

Igor

Hello,

Thank you, Igor, for your advice. That is what I am doing, and it is still possible to save the image of a completed ontotgraph, if not the .graph file itself.

I am wondering what is "UI" for in your message? What do you mean by "main functionality" ? I attache the error message behind the red triange, after trying to re-open the graph saved on the "Total" instance" of "Code activité économique CITI" class. What does "queue" means" in this message ? It seems to be related to the OntoGraph functionnality. Could it be corrected in a new release of Protégé desktop ?

Yours,

Jean-Louis Janin

There are various bugs manifesting in the UI quite frequently. Most of them do not disrupt the main functionality. Click on the red triangle to see the bug message. After closing the message box the red triangle disappears.

I don't use OntoGraph much but a couple of thoughts:

1) I didn't see what the error message was (but I can see there is one by the red triangle in the lower right corner). You might want to do Window>Show Log (about 3rd item from the bottom). That will show the log and the error message and you can send a screen shot of that. That will help debug the problem.

2) I notice you didn't run the reasoner in any of those screen captures. I doubt that will fix the problem but just wanted to point out make sure you do that. Especially for new users it is a good idea to run the reasoner often. I recommend after every change that could have some impact on the logic. If you have one error the reasoner can usually point you right to it (sometimes the messages are a bit cryptic if you aren't used to reading them but people on this list can help with that) but if you have say 5 or more errors the reasoner often can't give much more info than that the ontology is inconsistent.

Hello again,

Some screen shots attached. Why this error message when opening the

saged file's graph ?
