If you are into cycling in any way, you might like the opportunity for a friendly cycle round Birmingham.  Birmingham has a bit of a car centric attitude toward town planning, so it is great to be able to cycle around the center en mass and be a very visible part of the evening traffic.  Oh and we drop in at a pub on the way home. What’s not to like?

Here is a short video of last weeks Critical Mass.

Critical Mass, Birmingham, February 2012 from Tim Hodson on Vimeo.

A Critical Mass ride around central Birmingham. It was cold, getting close to if not below zero, but still a good ride.

Meet at Pigeon Poo park (by St Philips, Temple Row) for an 18:30 start.

One aspect of the mini-projects at #sssw11 was to create a one minute video that was both humorous and contained reference to some innovative semantic technologies.

Our Mini-Project team, Don’t Move the Plants was intrigued by the signage in the residencia, so took that as our inspiration.  It is worth noting that all the text translation seen in the video is as translated by Word Lens, an iPhone app which translates words right before your eyes.

Don’t Move the Plants comprised myself, Esther Lozano, Andrea Nuzzolese, Ferdinand Dhombres and Luca Greco.

I’m at risk of over explaining the joke, so here is our winning entry.

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.
