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

$ tracker3 extract /path/to/some/file.mp3
