7
9 tracker3 extract FILE
10
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.
