NAME

6       tracker3-extract - Extract metadata from a file.
7

SYNOPSYS

9       tracker3 extract FILE
10

DESCRIPTION

12       tracker3 extract reads the file provided and extracts any metadata it
13       can from this file, then displays the metadata on standard output.
14
15       The metadata is displayed as a SPARQL update command, that can be run
16       against a SPARQL endpoint to update its copy of the metadata.
17
18       The actual extraction is done by a separate process. This is done to
19       isolate the calling process from any memory leaks or crashes in the
20       libraries Tracker uses to extract metadata.
21
22       For more information see the libtracker-extract reference
23       documentation.
