RDF Transform extension not showing on OpenRefine GUI about rdf-transform

[AtesComp]

Check the version of Java you have installed. RDF Transform requires Java 11 to Java 17. Most installs for OpenRefine use the older Java 8.

See the install Prerequisites for more on the issue.

I'm assuming this solved the issue.

Not really. I'm using JDK 17.0.1 and OpenRefine 3.5.2

Make sure OpenRefine is running with Java 17. OpenRefine will use the system default. If Java 8 and Java 17 are installed or OpenRefine is bundled with the JRE, it may still be running Java 8. See the "refine" script file if you are using it. Also, check and set your Java environment variables for the proper version.

Alternatively, make sure Java 8 is uninstalled if you don't need it for other projects. Java 17 should run Java 8 code ok.

NOTE: The Mac kit currently includes Java by default. It is documented here and elsewhere. The bundled Java should be removed or redirected to a later version with the JAVA_HOME env variable.

Please update as this issues is almost assured to be a Java version issue. Try OpenRefine-beta2 as it bundles Java 11.
