Tracker is a first class object database, extensible tag/metadata database, search tool and indexer.
It can trawl through your hard drive and index existing files and data stores.
It has been designed from the ground up to be very lightweight (the tracker daemon consumes ~4MB of RAM in typical use) yet at the same time very fast too.
It provides a comprehensive, persistent and extensible storage system that can store and index almost any object. These objects can also have extensible user defined metadata and tags to create rich first class objects.
First class object support includes:
· Files
· Documents
· Music
· Images
· Videos
· Text Files
· Development Files
· Playlists*
· Notes*
· Applications*
· People/Contacts*
· Emails*
· Conversations*
· Appointments*
· Tasks*
· Bookmarks and History*
· Projects*
(* these services are not currently indexed at the moment but will be in later versions)
Product's homepage
Here are some key features of "Tracker":
· Desktop-neutral design (its a freedesktop product built around other freedesktop technologies like DBus and XDGMime but contains no GNOME specific dependencies)
· Very memory efficient and non-leaking (typical RAM usage 4 - 6 MB). Unlike some other indexers, tracker is designed and built to run well on lower memory systems with typically 128MB or 256MB memory. It should even be efficient enough to use on some mobile devices.
· Non-bloated and written in C for maximum efficiency.
· Small size and minimal dependencies makes it easy to bundle into various distro's including live cds.
· Fast indexing and unobtrusive - no need to index stuff overnight. Tracker runs at nice 10 so it should have a minimal impact on your system.
· Implements the freedesktop specification for metadata http://freedesktop.org/wiki/Standards/shared-filemetadata-spec
· Extracts embedded File, Image, Document and Audio type metadata from files.
· Extracts embedded metadata from HTML, PDF, PS, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), DVI, MAN, MP3 (ID3v1 and ID3v2), OGG, WAV, EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ), ZIP, ELF, REAL, RIFF (AVI), MPEG, QT and ASF files
· Supports the WC3's RDF Query syntax for querying metadata
· Provides support for both free text search (like Beagle/Google) as well as structured searches using RDF Query
· Respond in real time to file system changes to keep its metadata database up to date and in synch
· Fully extendable with custom metadata - you can store, retrieve, register and search via RDF Query all your own custom metadata
· Can extract a file's contents as plain text and index them
· Provides text filters for PDF, MS Office, OpenOffice (all versions), HTML and PS files.
· Can provide thumbnailing on the fly
Requirements:
· gtk+
· dbus
· dbus-glib
· libgmime
· gstreamer
