CeeMedia is a program for cataloguing your movie collection. It can retrieve information and cover images from places such as Amazon, IMDb, All Movie Guide, and AlloCiné. You can also write your own plugin for retrieving data from your favorite movie site. It also generally tries to provide the user with the most comfortable interface available for the task, while trying to follow the GNOME Human Interface Guidelines.
Alexandria is a GNOME application to help manage a book collection. It retrieves book information (including cover pictures) from several online libraries, allows you to search for a book (either by EAN/ISBN, title, authors, or keyword), can import and export data into ONIX, Tellico, and EAN/ISBN-list formats, generates Web pages from your libraries, allows marking your books as loaned, saves data using the YAML format, features an HIG-compliant user interface, shows books in different views that can be filtered or sorted, and handles book rating and notes.
SyncEvolution synchronizes personal information management (PIM) data like contacts, calenders, tasks, and memos via the SyncML information synchronization standard. SyncEvolution compiled for GNOME's Evolution supports all of these data items. Compiled for Nokia 770/N800/N810 Internet Tablets, Mac OS X, and the iPhone, it supports synchronizing the system address book. The command line tool 'syncevolution' (compiled separately for each of these platforms) executes the synchronization.
Network-config is a simple and easy to use program that helps in configuring the network interfaces for Linux-based operating systems. It allows you to have multiple configurations for the same computer, and to easily configure NAT for Internet sharing. It can also be used to scan for wireless networks. It is written in Perl and uses GTK2+, but also works as a command line program.
The chemical-mime-data package is a collection of data files to add support for various chemical MIME types on Linux/Unix desktops, such as KDE and GNOME. Chemical MIME types were proposed in 1995, though it seems they have never been registered with IANA. But they are widely used, and the project's aim is to support these important but unofficial MIME types. Initial data was taken from "The Chemical MIME Home Page" of Henry Rzepa.
DWI, Data With Interaction, is an Object-to-Relational Mapping (ORM)-based RAD (Rapid Application Development) system for rapidly creating data-driven desktop GUI applications. It maps SQL tables into several object systems, including QOF, GLib GObjects, and GTK/GNOME. It can be used with the Glade GUI designer. It supports multiple databases through ODBC and libdbi.
