  1. On March 19th, LG introduced webOS Open Source Edition with the intention of opening up webOS again to the world of development to move beyond TVs. This is the second time an open-source version of webOS has been released, the first coming under the failed tenure of HP back in 2011. LG Chief Technology Officer Dr. I.P. Park. “webOS has come a long way since then and is now a mature and stable platform ready to move beyond TVs.” webOS Open Source Edition Architecture The following figure shows the overall architecture of webOS Open Source Edition (OSE). webOS OSE consist of a set of layers: Core Applications, Application Framework, Managers & Services, Base Components, and BSP/Kernel. Core Applications webOS OSE has Core applications as the top layer and this layer includes System UI and System app. System UI includes apps that are related to the basic user interface, such as Home Launcher and Notification. These apps are usually implemented using QML. System app includes Settings app and web browser. Settings app is used to control the system properties and implemented using Enact. As a web browser, the Chromium browser is used. Application Framework To help developers creating better apps and services, webOS OSE provides enhanced options and environments compared to developing solely with HTML5, JavaScript, or CSS. The web app framework Enact, which is equivalent to jQuery, and Software Development Kit (SDK) are provided. Enact Enact is a web app framework optimized for developing web apps for webOS OSE. For more information and structure of Enact, refer to Enact developer site. Enact is also an open source project and is provided separately from webOS OSE. SDK The SDK provides a development environment for web apps and services. In this release of webOS OSE, we provide a CLI-based SDK for developing and installing web apps and services. Web apps can be packaged with services that are developed using Node.js. For more details on development/packaging of web apps and services, see Command Line Interface. Managers & Services Managers & Services layer includes the following components. System and Application Manager System and Application Manager (SAM) oversees the behavior of apps. SAM manages each app throughout its lifecycle, including the installation, launch, termination, and removal of the app. There are two types of apps in webOS Open Source Edition: native app and web app. In case of a web app, actual launching and management are performed by Web Application Manager as described below. Web Application Manager Web Application Manager (WAM) is responsible for launching and managing web apps. In addition, WAM performs CPU usage optimization, status monitoring and recovery processing, and access privileges management, all based on the running status of web apps. Luna Surface Manager Luna Surface Manager (LSM) is a component that works as a graphics manager. LSM displays graphical elements on the screen, manages the composition of these elements, and performs the event handling for input devices such as keyboard and pointer. LSM is also responsible for the execution and management of System UI, such as Home Launcher and Notification. LSM is implemented using Qt, and System UI is implemented using QML. Activity Manager Activity Manager is responsible for managing and executing activities requested from services. An activity is requested along with a specific condition, and it is triggered when the condition is met. You can configure the activity to perform tasks such as automatic execution of specific services, callback requests, and so on. uMediaServer uMediaServer (uMS) is a module that works as a server for the webOS media framework. uMS provides interfaces for media playback, manages resources, pipelines, and their policies, and manages the lifecycle of the media player. Base Components Base Components layer includes the following components. LS2 LS2, also called Luna Bus, is a system bus used by webOS OSE. LS2 manages the interface registration and invocation required for the interconnection among apps and services. Originally based on D-bus, LS2 has been enhanced to optimize the performance for embedded device environment. Web Engine webOS OSE uses Chromium as the web engine. A web engine is the module that loads and parses a web app (or web page) consisting of HTML, CSS, and JavaScript, and performs all tasks required to represent the web app on the screen, such as layering and rendering. Currently the web runtime environment of webOS OSE is implemented according to the multi-process model of Chromium. Therefore, each web app is run as a separate independent process. Chromium also includes browser logics a.k.a. Chromium browser which webOS OSE provides as the default browser app. DB8 DB8 is an embedded JSON database that supports data storing and retrieving in the structure of key-value store. webOS OSE uses LevelDB as the back-end database. The default service associated with DB8 is the com.webos.db. The com.webos.tempdb, which allows you to configure temporary storage in memory, is also provided. Node.js The service framework based on Node.js is provided so that you can implement services with JavaScript language. Node.js is a JavaScript framework that is typically run on a server. In webOS OSE, Node.js has been built in to facilitate service development. For more information on developing services based on Node.js, see JS Services. BSP/Kernel BSP/Kernel layer consists of several components to support Raspberry Pi 3. Typically, it provides evdev for event processing, Mesa for graphics support, and Wi-Fi and wired LAN for connectivity.

  2. So did you guys see that smartwatch calling that Audi at CES? Turns out it's openwebos! Exclusive: The hottest smartwatch of CES isn't running Android Wear — it's Open webOS LG and Audi's smartwatch collaboration is the most desirable wearable of CES 2015, and while the carmaker says it's just a prototype, the device offers a tantalizing glimpse of future LG wearables. Or at worst an agonizing look at a beautiful watch we'd love to own. We tracked down the Audi/LG watch — still officially nameless, by the way — in Las Vegas today, and we can exclusively reveal that it's not running Android Wear as originally believed. In fact, it's packing completely different software based on LG's Open webOS. Source: http://www.androidcentral.com/lg-audi-watch-android-wear-webos
  3. PALO ALTO, Calif., Jan. 25, 2012 – HP today began executing its plan to deliver an open webOS by committing to a schedule for making the platform’s source code available under an open source license. The company aims to complete this milestone in its entirety by September. HP also announced it is releasing version 2.0 of webOS’s innovative developer tool, Enyo. Enyo 2.0 enables developers to write a single application that works across mobile devices and desktop web browsers, from the webOS, iOS and Android platforms to the Internet Explorer and Firefox browsers – and more. The source code for Enyo is available today, giving the open source community immediate access to the acclaimed application framework for webOS. By contributing webOS to the open source community, HP unleashes the creativity of hardware and software developers to build a new generation of applications and devices. “HP is bringing the innovation of the webOS platform to the open source community,” said Bill Veghte, executive vice president and chief strategy officer, HP. “This is a decisive step toward meeting our goal of accelerating the platform’s development and ensuring that its benefits will be delivered to the entire ecosystem of web applications.” The webOS code will be made available under the Apache License, Version 2.0, beginning with the source code for Enyo.
