How do I convert data?

Hop into your conversion cockpit and pull the conversion trigger:

bash-3-2$ cd ~/Desktop/source/rpi-edu-lebot/exercise-jogging-statistics/version/2011-Jan-24
bash-3-2$ ./exercise-jogging-statistics.sh
bash-3-2$ ls automatic/

That creates a bunch of Turtle in automatic/. Pulling the trigger again will not do anything because it knows that things are up to date and the enhancement conversion is not ready. You'll need to tweak enhancement parameters first...

See Generating enhancement parameters for a discussion of how the enhancement parameters are created for you when they are not present.

What control do I have over what gets converted?

Many of the shell environment variables shown by cr-vars.sh can be used to affect the conversion automation.

• CSV2RDF4LOD_CONVERT_MACHINE_URI - names the machine the conversion is performed on.
• CSV2RDF4LOD_CONVERT_PERSON_URI - names the person associated to the machine's user account.
• CSV2RDF4LOD_CONVERT_SAMPLE_SUBSET_ONLY - set to true to only convert CSV2RDF4LOD_CONVERT_NUMBER_EXAMPLE_ROWS of input before curtailing conversion. This is useful when you have a large dataset and just want to see part of the output during development.
• CSV2RDF4LOD_CONVERT_EXAMPLE_SUBSET_ONLY - omits the full conversion (for debugging/enhancement development).
• CSV2RDF4LOD_CONVERT_DEBUG_LEVEL - logger level (for debugging).
• CSV2RDF4LOD_PUBLISH - whether or not to aggregate the automatic/* conversion files into publish/.
• CSV2RDF4LOD_PUBLISH_SUBSET_VOID_NAMED_GRAPH - the named graph to load void metadata when publishing.
