How to install the Protege plugin?

[Greg Soulsby]

I am following the plugin instillation instructions here:

https://ontop-vkg.org/tutorial/basic/setup.html#database-setup

but the plugin is not visible when I start Protege. There is no Ontop tabs from Windows->Tabs and there is no JDBC options from File -> Preferences.

The instructions say: 

    0 download and unzip the archive and go into its folder

    1 Run run.bat

But there is no "run.bat" in the ontop-cli-5.0.1 directory, "run.bat" is in the Protege-5.5.0 directory, which, correctly, starts Protege.

In the ontop-cli-5.0.1 directory there is "ontop.bat". When I run "ontop.bat" I can do "ontop" in a dos window and it responds with Ontop options, so the "ontop.bat" script seems to have run ok.

I have tried re-booting the laptop (Windows 11) and re-installing Protege , but no luck.

Where am I going wrong?

Hi,

 run.bat is the script to start Protege, in the protege distributions.

ontop.bat is the script for onto-cli.

Did you see any error message when starting protege?

Best regards,

Guohui

• Did you see any error message when starting protege? No. As far as I know its a perfect start, but no Ontop. Posting logs below.
• There is nothing about Ontop in the Protege plugins directory. Should there be? There is nothing in the install process that puts something there, right?
  
• In the system Path environment variables there is an entry "C:\Programs_other\protege\ontop-cli-5.0.1;" 
• So Protege finds Ontop because its in the Path, not because there is an entry in the \plugins directory? Either ways its not being found  
• I should have mentioned that this is a re-install. Ontop in Protege was working on this machine some time ago.

Appreciate your help Guohui

ok, I think I mis-understood. I got Ontop running from the Protege / Ontop bundles no problem.

Maybe you cant install Ontop as a plugin to an already installed Protege? Doesn't matter, its running fine from the bundle.

[Guohui Xiao]

Hi Greg,

There are might be an issue about which version you are using.

- Ontop 4.x requires Protege 5.5/Java 8.

- Ontop 5.x requires Protege 5.6/Java 11

You can manually install the Ontop protege plugin into the plugins directory, but it won’t work if you mixed wrong versions. 

For example, in you case, Ontop 5.0.1 does not work with Protege 5.5.

The safes and easiest option is to use our bundles, which combines right versions of Protege and Ontop plugin.

Best regards,

Guohui

Yes, thanks Guohui, from now on its bundles only for me.

Many thanks,
