On this page, we collect definitions of terms used in Plasma. Its main purpose is to get developers' terminology synchronized.

Workflow

Workflow is the sequence of actions a user performs to accomplish a task. A workflow involves applications, but can also lead the user across devices.

Example:

Writing a report and sending it to your boss
Importing photos and reviewing them
Interacting friends (catching up on the social network, taking part)
Running into articles while working on the desktop, reading them on your tablet later
Downloading a movie on the laptop, watching it on the TV/Media Center

Workspace

The workspace's purpose is to guide the user through her workflow, across applications. A workspace runs on a specific device, such as Desktop, tablet, etc, and forms part of workflows across devices. The workspace is a generic term for all the software component intended to provide the final UX for the global work environment, the minimal "fixed" running user interface that manages documents, applications (opening, closing) and global system properties such as notifications or attached hardware devices.

Examples:

Plasma Desktop (or "KDE Plasma Desktop")
Plasma Netbook (or "KDE Plasma Netbook")
Plasma Active (or "KDE Plasma Active" (in case that wasn't clear by now))

(KDE is used as umbrella brand in this context, standing for "created by the KDE community")

Shell

The shell, technically speaking, is the binary that will load and display the UI parts of the "Workspace". It doesn't provide its own UI, it may be tied to a particular formfactor.

Examples (these refer *only* to binary names):

plasma-desktop
plasma-netbook
plasma-device

Current Implementation

The term shell does not include Plasmoids loaded into it, it's provides the implementation of the Corona and defines how the views are bound to it. These views hold containments, which then load applets. The particular shell and the final UX are only tied in part.

Activities

Active

Active defines a set of user interface guidelines for applications to integrate well with Plasma workspaces across different devices.

We would also like you to acknowledge that the term to describe a certain avian animal. Or, to paraphrase it: THE BIRD IS THE WORD.
