Zeitgeist is a service which logs the users’s activities and events, anywhere from files opened to websites visited and conversations. It makes this information readily available for other applications to use. It is able to establish relationships between items based on similarity and usage patterns.

Jsonrpc-GLib is a library to communicate with JSON-RPC based peers in either a synchronous or asynchronous fashion. It also allows communicating using the GVariant serialization format instead of JSON when both peers support it. You might want that when communicating on a single host to avoid parser overhead and memory-allocator fragmentation.

VTE is a library (libvte) implementing a terminal emulator widget for GTK+, and a minimal sample application (vte) using that. Vte is mainly used in gnome-terminal, but can also be used to embed a console/terminal in games, editors, IDEs, etc.

Yelp-tools is a collection of scripts and build utilities to help create, manage, and publish documentation for Yelp and the web. Most of the heavy lifting is done by packages like yelp-xsl and itstool. This package just wraps things up in a developer-friendly way.

Calls can make and answer phone calls using different backends, such as ModemManager for phones and SIP for VoIP.

Glib-networking contains the implementations of certain GLib networking features that cannot be implemented directly in GLib itself because of their dependencies. Currently it contains GnuTLS and OpenSSL-based implementations of GTlsBackend, a libproxy-based implementation of GProxyResolver, GLibproxyResolver, and a GNOME GProxyResolver that uses the proxy information from the GSettings schemas in gsettings-desktop-schemas.

Builder aims to be an integrated development environment (IDE) for writing GNOME-based software. It features fuzzy search, auto-completion, a mini code map, documentation browsing, Git integration, an integrated profiler via Sysprof, debugging support, and more.

While aiming at simplicity and ease of use, gedit is a powerful general purpose text editor.

D-Spy is a tool to explore and test end-points and interfaces of running programs via D-Bus. It also ships a library for integration into development environments.

The GNOME User Documentation explains how to use the GNOME desktop and its components. It covers usage and setup of the core GNOME programs by end-users and system administrators.

GNOME is a graphical desktop environment. It includes a wide variety of applications with a common interface for browsing the web, editing text and images, creating documents and diagrams, playing media, scanning, and much more.

libgit2-glib is a GLib wrapper library around the libgit2 Git access library. It only implements the core plumbing functions, not really the higher level porcelain stuff.

PortableXDR is an implementation of External Data Representation (XDR) Library. It is a standard data serialization format, for uses such as computer network protocols. It allows data to be transferred between different kinds of computer systems.

GTX is a small collection of convenience functions intended to enhance the GLib testing framework. With specific emphasis on easing the pain of writing test cases for asynchronous interactions.

Libwnck is the Window Navigator Construction Kit, a library for use in writing pagers, tasklists, and more generally applications that are dealing with window management. It tries hard to respect the Extended Window Manager Hints specification (EWMH).

PhoDav was initially developed as a file-sharing mechanism for Spice, but it is generic enough to be reused in other projects, in particular in the GNOME desktop.

Geoclue is a D-Bus service that provides location information. The primary goal of the Geoclue project is to make creating location-aware applications as simple as possible, while the secondary goal is to ensure that no application can access location information without explicit permission from user.

GtkGLExt is an OpenGL extension to GTK+. It provides additional GDK objects which support OpenGL rendering in GTK+ and GtkWidget API add-ons to make GTK+ widgets OpenGL-capable.

Vala is a programming language using modern high level abstractions without imposing additional runtime requirements and without using a different ABI compared to applications and libraries written in C. Vala uses the GObject type system and has additional code generation routines that make targeting the GNOME stack simple.

Liblarch is a Python library built to easily handle data structures such as lists, trees and acyclic graphs. There's also a GTK binding that will allow you to use your data structure in a Gtk.Treeview.

Liblarch support multiple views of one data structure and complex filtering. That way, you have a clear separation between your data themselves (Model) and how they are displayed (View).

GUPnP-IGD is a library to handle UPnP IGD port mapping.

Tracker is an advanced framework for first class objects with associated metadata and tags. It provides a one stop solution for all metadata, tags, shared object databases, search tools and indexing.

GNOME Music is the new GNOME music playing application that aims to combine an elegant and immersive browsing experience with simple and straightforward controls.

This package provides plugins for the Eye of GNOME (EOG) image viewer, notably:

• EXIF Display, which displays camera (EXIF) information;

• Map, which displays a map of where the picture was taken on the side panel;

• Slideshow Shuffle, to shuffle images in slideshow mode.
