IMG

Image creator

Intel

principle founding company (along with Nokia) of the Meego project

K

Kernel (linux)

is the open source core of the operating system and without which we would not have Meego! See MeeGo kernel documentation for contributors

Kickstart files (.ks)

provide a list of packages and settings to use for automated installs. See Image Creation

L

LSB (Linux Standard Base):

The goal of the LSB is to develop and promote a set of open standards that will increase compatibility among Linux distributions and enable software applications to run on any compliant system even in binary form.

M

MADDE

Maemo Application Development and Debugging Environment and offers the following features:

• Command-line cross-compiling
• Multi-platform support (Linux (32-bit/64-bit), Windows, Mac OS X)
• Configurable for different targets & toolchains
• Client for the device to simplify the development process

It will used as part of future releases of the MeeGo SDK, along with QEMU, to enable cross-OS development.

Maemo

a software platform developed by Nokia for smartphones and Internet Tablets. It was initially based on the Debian Linux distribution. One of the predecessors of MeeGo, along with Moblin.

Maemo 5

the default operating system on the Nokia N900, and current latest stable and independent version of Maemo. Based on the GTK toolkit. Aliases: Fremantle

Maemo 6

see MeeGo-Harmattan

Maemo 6 UI framework

see MeeGo Touch framework

MeeGo

an open source, Linux project which brings together the Moblin project, headed up by Intel, and Maemo, by Nokia, into a single open source activity. Managed by the Linux Foundation. The important thing to note that you end users will mostly be using an edition of MeeGo, MeeGo itself is not a single product (that’s why "will X run/get MeeGo" is a bad question), just like people are using a Linux distributions, not Linux (as in kernel) alone.

MeeGo Compatible

something that implements the MeeGo APIs, but is not necessarily based on MeeGo Core (for example Meego-Harmattan).

MeeGo Core 1.0

the base of every MeeGo system (diagram), and described in detail here. It contains:

• Kernel based on Linux 2.6.33
• DeviceKit and udev for interacting with hardware devices
• Modern 2D/3D graphics stack including Kernel Mode Setting, non-root X
• Voice and data connectivity with Connman connection manager, Ofono telephony stack and BlueZ Bluetooth
• Qt 4.6
• Universal Plug and Play (gUPnP)
• Media frameworks
• Next generation file system BTRFS, as the default file system
• Does NOT contain a user interface or end-user applications

MeeGo Garage

A client app installer in the MeeGo 1.0 Netbook release containing miscellaneous applications not part of the official MeeGo release and open for contributions from community. The name "Garage" may be changed in future releases. Ongoing community work is happening to create the official community repositories.

MeeGo Handheld

MeeGo Core + MeeGo Touch Framework + Reference Handheld UX (not yet released).

MeeGo Hardware adaptation project for the N900

Nokia as founding member of MeeGo project is using N900 as the ARM reference platform of MeeGo at the moment. This means that we have an active project that focuses to make a MeeGo hardware adaptation for the N900. The goal of the project is thus to open as much N900 specific drivers as possible in MeeGo scope.

MeeGo Hardware adaptation project for the N8x0

a 'skunkworks' project by the maemo.org community and others to bring MeeGo to Nokia N8x0, hence not a vendor-pushed hardware adaptation. Initially focus will be on Nokia N810. Some additional work to add support for ARMv6+VFP is also included in this.

MeeGo-Harmattan

the default operating system of the Nokia N9. Successor of Maemo 5, but based of the Qt toolkit. Originally named Maemo 6, but later rebranded as MeeGo-Harmattan (provisional name). It is MeeGo compatible (that is, has a MeeGo API) but is not to be confused with MeeGo 1.0 Handheld as it is NOT based on MeeGo Core. MeeGo-Harmattan will not be released as a Nokia product for the N900. Aliases: Harmattan, Maemo 6, MeeGo 1.0 N.

MeeGo Netbook

MeeGo Core + Reference Netbook UX

MeeGo SDK

A software development kit for MeeGo

MeeGo Touch Framework (MTF)

provides the features needed for developers creating applications for touch-enabled devices. Features include standardized window navigation, list and other widget behavior, and common theming for components.

MeeGo Web RunTime

Web Runtime (WRT) allows web developers to use standard web languages — HTML, CSS, and JavaScript — to create applications for mobile devices. WRT exposes the features of the underlying platform so that applications can interact with device data and combine location-based context with web information.

MeeGo 1.0 N

A name which has appeared on some Nokia slides as a synonym for Harmattan. See MeeGo-Harmattan.

Moblin

short for 'mobile Linux', is an open source operating system and application stack for Mobile Internet Devices (MIDs), netbooks, nettops, and embedded devices. One of the predecessors of MeeGo, along with Maemo.

Moblin 2.1

last stable independent release of Moblin

Moblin 2.2

see Meego 1.0 Netbook

N

Nokia

principle founding company (along with Intel) of the Meego project

Nokia Qt SDK

A custom version of the Qt SDK, which includes additional functionality for developing for Symbian/Maemo devices (with announced MeeGo support later on). These include tools for cross compiling (see MADDE) and simulation. Not to be confused with the Qt SDK as the two are not interchangeable due to a custom mix of features (neither is a a superset of the other)

N900

Nokia ARM powered handheld phone for open Meego development. See ARM/N900

Netbook

is one of the key components and deliverables of the Meego project http://meego.com/devices/netbook/

O

OBS (OpenSuse Build System) :

The Opensuse Build Service. is an open and complete distribution development platform that provides a transparent infrastructure for development. The service provides software developers with a convenient and easy to use tool to create and release open source software for openSUSE and other Linux distributions on different hardware architectures and for a broad user audience. See Build System

OCS (Open Collaboration Services) :

a web API for browsing application catalogues, doing event and contact discovery OCS API. Also, OBS command line client

see UI Extensions for Mobile

OSSO (Open Source Software Operations):

It was a department inside Nokia responsible for producing Maemo. It has been replaced by Maemo Software.

OTS (Open Test System):

Suite of testing tools and configuration files for managing reproducible QA testing. See OTS Wiki

P

PA (PulseAudio)

is the low level sound system component used by Meego. See Quality/TestSuite/PulseAudio Test Plan

Q

QML

a Declarative UI tool, in effect a markup language that defines UI elements and their behavior in a declarative manner, allowing, snappy, whizzy UIs. Present in Qt4.7+

Qt

a cross-platform application and UI framework. Using Qt, you can write web-enabled applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code.

Qt Quick

the Qt User Interface Creation Kit, which consists of QML, a specialized editor in QtCreator and all-around support for the declarative approach. Present in Qt4.7+. Aliases: Qt Declarative, Declarative UI, Bauhaus.

Qt SDK

The software development kit for the Qt framework

QtMobility

extends Qt with libraries providing additional features for applications targeting mobile platforms. These include the Service Framework and Contact and Bearer Management APIs, Messaging, Sensors, Camera, etc.

R

Reference Netbook UX

a reference (example) implementation of a user interface for netbooks, utilizing Moblin’s Clutter-based MX toolkit. It is expected to be replaced or augmented with manufacturer provided user interfaces/system applications on actual devices.

Reference Handheld UX

a reference (example) implementation of a user interface for handheld devices, based on the MeeGo Touch framework. It is expected to be replaced or augmented with manufacturer provided user interfaces/system applications on actual devices.

UI Extensions for Mobile

UI Extensions for Mobile is an extension library for Qt, which contains more than 50 UI elements tailored for mobile user experience. There is a proposal to use UI Extensions for Mobile and Qt together with Direct UI as a replacement for the existing S60 'Avkon' set of UI elements in Symbian^4, but has been demonstrated to work on Maemo, too. UI Extensions for Mobile was previously known as Orbit and has been open sourced. Aliases: Uiemo, Orbit
