About Tracker
=============
Tracker is a semantic data storage for desktop and mobile devices.
Tracker uses W3C standards for RDF ontologies using Nepomuk with
SPARQL to query and update the data.
Tracker is a central repository of user information, that provides two
big benefits for the user; shared data between applications and
information which is relational to other information (for example:
mixing contacts with files, locations, activities and etc.).
IMPORTANT!
==========
The change in cardinality to nfo:hasMediaStream from 1 to many may force
a reindex for any existing Tracker installation. This change in ontology
is _NOT_ supported automatically.
It is recommended to use:
tracker-control --backup /path/to/backup.db
In case you later need to:
tracker-control --restore /path/to/backup.db
Forgive any disruption this may cause!
News
====
The main changes since 1.0.x are:
* New Feature: Extractor now supports eBook and Comic book formats
* New Feature: Extractor now supports BMP files
* New Feature: Data Provider: Now there are TrackerDataProvider and
TrackerEnumerator interfaces to allow 3rd parties to supply their own
data to Tracker to be indexed, for example for an online or proprietary
service
* New Feature: Extractor is now 'crash-aware' that being, we have a
separate data source for content that can't be extracted to avoid
repeated failures from tracker-extract. This also survives through
crashes that may occur due to attempted extractions
* build: Updated doap file (added programming language and category
is now "core")
* build: Improve firefox and thunderbird detection to avoid warnings
in console
* build: Removed all GNU_SOURCE additions in sources, use
AC_USE_SYSTEM_EXTENSIONS instead
* build: Fixed many unit tests that were not properly isolated
* build: configure now has an --enable-minimal option to ONLY build
tracker-store
* build: Reduce vala generated source warnings from GCC
* build: Use major version only PkgConfig files. Previously, we had
$library-$major-$minor (e.g. tracker-sparql-1.2, when it should be
tracker-sparql-1.0) to avoid creating unnecessary work for developers
using Tracker. This release corrects this and it was planned originally.
* build: Include COPYING*GPL files in tarball
* build: Generate Vala bindings from GIR for libtracker-miner,
libtracker-control
* build: Improved many GIR annotations for nullable cases in
libtracker-miner, libtracker-control
* build: Avoid using rpath where possible
* build: Make check fails to generate test reports
* build: Remove --enable-guarantee metadata, always guarantee
nie:title and nie:contentCreated
* build: Added CC_CHECK_FLAGS_APPEND m4 macros from xinelib/systemd
projects to check GCC compiler flags we can use
* ontology: nfo:hasMediaStream no longer has a max cardinality of 1,
this may mean a reindex is needed
* libtracker-bus: Fixed a crash in query_async() where splice async
operation is cancelled
* libtracker-bus: Fixed a bug where tracker-stats showed no
information with Vala 0.24+
* libtracker-sparql: All TrackerSparqlConnection APIs throw
GLib.Error due to GUnixFDList _append() API
* libtracker-sparql: Move TRACKER_ const definitions to Tracker
namespace, i.e. Tracker.DBUS_*
* libtracker-miner: Fixed reference leak with TrackerTaskPool when
using external data miners
* libtracker-miner: Add new API tracker_decorator_fs_prepend_file()
as part of 'crash-aware' feature.
* libtracker-miner: PkgConfig file now requires libmediaart (when
dependent) privately
* libtracker-extract: Fixed broken EXIF GPS coordinate extraction
* libtracker-extract: There is no longer an example in the examples/
directory as this library is now private
* tracker-extract: Fixed missing TRACKER_EXTRACTORS_DIR env var that
was removed at some stage
* tracker-extract: Cleaned up signal handling, SIGALRM and SIGABRT no
longer used
* tracker-extract: [DOC] Catch more MS Office MIME types supported
* tracker-extract: [MP3] Fixed mp3 parsing for ID3v24 or ID3v23 tags
* tracker-extract: [ISO] Extract language, copyright and author
information about ISO images using new ontology
* tracker-extract: [ODT] Improved extraction of content so we don't
stop on embedded tabs and line breaks
* tracker-extract: [GIF] Support giflib 5.1.0 as well as earlier versions
* tracker-stats: Now EXPRESSIONS can be used to filter stats shown
* tracker-stats: Now only common and fallback RDF types are shown by
default, --all can be used to old behaviour
* tracker-info: Add --resource-is-iri or -i to avoid filename to URN
lookups
* tracker-info: Don't show "(null)" for nie:InformationElements with
no nie:url
* tracker-control: Added a lot of strings previsouly untranslated
* tracker-control: Removed shorthand command line switches for less
common arguments (--list-*, --pause-details)
* tracker-control: Added --watch command line option to watch changes
to the database.
* tracker-miner-fs: By default, ignore directories with
'.trackerignore' file inside
* tracker-miner-apps: New process to mine data about applications,
previously part of tracker-miner-fs. Can be disabled with
--disable-miner-apps
* tracker-miner-user-guides: New process to mine data about user
guides and help content, previously part of tracker-miner-fs. Can be
disabled with --disable-user-guides
* tracker-writeback: Support GIFs
* tracker-preferences: Removed fixed column for indexed locations,
column header text was cut off
* tracker-preferences: Don't use Stock.* deprecated since Gtk+ 3.10
* tracker-preferences: Added suggestion to reindex OR restart
depending on configuration changes applied
* tracker-preferences: General UI clean up and modernization fixing
many deprecations where old GTK+ widgets were used
* tracker-preferences: Added 'control' tab to allow users to enable
finer control of what's indexed (e.g. numbers - which are normally disabled)
* tracker-preferences: Add AppData with screenshots for app stores
* tracker-needle: Add AppData with screenshots for app stores
* tracker-sandbox: Setup xdg-user-dirs too
