The CorneliOS login screen. As CorneliOS is a multi-user system you need to login before you can use built-in tools and applications.
Each CorneliOS site has at least one user called "root", who is the system superuser. Only root can manage user accounts and has automatically access to all system objects and resources. The CorneliOS system logic resembles common BSD/UNIX systems in many ways.
This is the start page you can see after loggin into the CorneliOS environment. We're in "full screen" mode here, where each application occupies the entire web browser window - CorneliOS applications then look like common web applications. It is also possible to switch to the "windowing" mode (see below), your web browser window is then transformed into a desktop and multiple CorneliOS applications can then be run in separate windows.
The CorneliOS file system browser can be used to manage files and directories on your CorneliOS system. It is more or less the CorneliOS pendent of the Microsoft Windows explorer or the Apple MacOS Finder. The file system browser can be used to upload, move, rename or delete files. It also allows you to change object settings (access rights, backups, logging and many more options offered by VFS, the CorneliOS Virtual File System), and it includes a file editor that can be used to instantly change the content of many standard format files.
The CorneliOS Control Panel is where you can change system settings (as "root" user) as well as your personal settings. It it more or less the CorneliOS pendent of the Microsoft Windows Control Panel or to the Apple MacOS Preferences. But it offers more than just the standard features (system management, user management, application management) you would generally expect: it also includes a Database Management System (DBMS) as well as a fully featured Content Management System (CMS) what allows to create and maintain websites on your CorneliOS powered webserver.
The CorneliOS CMS (Content Management System) allows to create and maintain websites on your CorneliOS site. The CorneliOS CMS is user friendly and allows to run multiple sites in parallel, it offers a tree based site structure and an inline editor, full support for the CorneliOS VFS (Virtual File System) features including access control, backups and logging, full support for the CorneliOS CoHTML and CoSCRIPT parsers as well as an easy to use template editor.
The advanced CMS editor offers more options than the inline editor and can be used to edit both the page structure and the content objects. The CorneliOS CMS uses an object-oriented logic to build websites, which means that all content elements are separated from the page source and can be reused on mulitple pages (and even on different websites).
The CorneliOS desktop allows to run multiple CorneliOS application inside a single web browser window. The desktop looks like a common operating system, but it's currently still an alpha prototype - most energy is currently spent on finishing the system core features and the "full screen" mode (common web app view).
The CorneliOS terminal is a shell offering direct access to the system core and it's commands and utilities. The file system and commands have been inspired by BSD/UNIX as well as by other OSes such as Plan9 or Multics for example. Usually you don't need the terminal for your daily work, but as it offers direct access to low level system features it is the ultimate tool for the "dirty work" and special tricks (so it's got a similar role as the terminal on Apple's MacOS X).
