Hi there,

You have to do several things.

1. Build with libstreamanalyzer supported (see configure options)
2. Have no other extractors available for a mime-type to be use it. This 
can be done changing the environment before starting the command:

  export TRACKER_EXTRACTORS_DIR=/tmp

This means there will be no extractors found and LSA should be used.

We should probably have a command line option for this if LSA is available.

What Philip says is also true, the ontology generated is not inline with 
what Tracker expects so you might have some issues when using it. We 
already have to strip all nfo:FileDataObject properties from the 
generated sparql because the miner-fs already does that. There may also 
be some ontologies missing we expect and/or some just not in our ontology.
