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

           statistics
