NAME
tracker3-info - Retrieve all information available for a certain file.
SYNOPSIS
tracker3 info [options...] <file1> [[file2] ...]
DESCRIPTION
tracker3 info asks for all the known metadata available for the given file.
Multiple file arguments can be provided to retrieve information about multiple files.
The file argument can be either a local path or a URI. It also does not have to be an absolute path.
OPTIONS
-f, --full-namespaces
-
By default, all keys and values reported about any given
file
are returned in shortened form, for example,
nie:title
is shown instead of
http://tracker.api.gnome.org/ontology/v3/nie#title. This makes things much easier to see generally and the output is less cluttered. This option reverses that so FULL namespaces are shown instead.
-c, --plain-text-content
-
If the resource being displayed has nie:PlainTextContent (i.e. information about the content of the resource, which could be the contents of a file on the disk), then this option displays that in the output.
-i, --resource-is-iri
-
In most cases, the
file
argument supplied points to a URL or PATH which is queried for according to the resource associated with it by
nie:url. However, in cases where the
file
specified turns out to be the actual URN itself, this argument is required to tell "tracker3 info" not to do the extra step of looking up the URN related by
nie:url.
For example, consider that you store URNs by the actual URL itself and use the unique nie:url in another resource (which is quite reasonable when using containers and multi-resource conditions), you would need this argument to tell "tracker3 info" that the file supplied is actually a URN not URL.
-t, --turtle
-
Output results as Turtle RDF. If -f is enabled, full URIs are shown for subjects, predicates and objects; otherwise, shortened URIs are used, and all the prefixes Tracker knows about are printed at the top of the output.
