TRACKER3-EXTRACT(1)             Tracker manual             TRACKER3-EXTRACT(1)

NAME
       tracker3-extract - Extract metadata from a file.

SYNOPSYS
       tracker3 extract FILE

DESCRIPTION
       tracker3 extract reads the file provided and extracts any metadata it
       can from this file, then displays the metadata on standard output.

       The metadata is displayed as a SPARQL update command, that can be run
       against a SPARQL endpoint to update its copy of the metadata.

       The actual extraction is done by a separate process. This is done to
       isolate the calling process from any memory leaks or crashes in the
       libraries Tracker uses to extract metadata.

       For more information see the libtracker-extract reference
       documentation.

OPTIONS
       -o, --output-format=<FORMAT>
           Choose which format to use to output results. Supported formats are
           sparql, turtle and json-ld.

EXAMPLES
       Using command line to extract metadata from a file
           $ tracker3 extract /path/to/some/file.mp3
