A HowTo for running Jena Eyeball on Mac OSX.

1. Download the eyeball package somewhere convenient.
2. Create the following script somewhere convenient, then add it to your PATH.

   #!/bin/bash
   # script to run eyeball on a file or files
   
   FILES=$@
   FILEBASE="/YOUR/PATH/TO/eyeball-2.3"
   CLASSPATH="$FILEBASE/lib/antlr-2.7.5.jar:\
   $FILEBASE/lib/arq-extra.jar:\
   $FILEBASE/lib/arq.jar:\
   $FILEBASE/lib/commons-logging-1.1.1.jar:\
   $FILEBASE/lib/commons-logging.jar:\
   $FILEBASE/lib/concurrent.jar:\
   $FILEBASE/lib/eyeball.jar:\
   $FILEBASE/lib/icu4j_3_4.jar:\
   $FILEBASE/lib/iri.jar:\
   $FILEBASE/lib/jazzy-core.jar:\
   $FILEBASE/lib/jena.jar:\
   $FILEBASE/lib/jenatest.jar:\
   $FILEBASE/lib/json.jar:\
   $FILEBASE/lib/junit4.jar:\
   $FILEBASE/lib/log4j-1.2.12.jar:\
   $FILEBASE/lib/slf4j-api-1.5.6.jar:\
   $FILEBASE/lib/slf4j-log4j12-1.5.6.jar:\
   $FILEBASE/lib/stax-api-1.0.jar:\
   $FILEBASE/lib/wstx-asl-3.0.0.jar:\
   $FILEBASE/lib/xercesImpl.jar:\
   $FILEBASE/lib/xml-apis.jar:\
   $FILEBASE/lib/xsdlib.jar:\
   $FILEBASE/lib:\
   $FILEBASE/mirror:\
   $FILEBASE/etc"
   
   for file in $FILES
   do
   echo "======================================="
   echo "    Checking $file"
   echo "======================================="
   java -classpath "$CLASSPATH" jena.eyeball -check $file
   
   done

3. You may want to tell Jena what schemas you are using. I did this by downloading all the schema rdf or n3 files I could find to the {eyeball_install_dir}/mirror direectory, then adding the following to the end of the java command line:

   -assume owl dc-all `ls $FILEBASE/mirror/*`
   

   This means that we don’t get so many ‘predicate not declared’ messages when we will only ignore them.

Don’t you just love Java and its classpath loveliness… NOT.
