Openharmony is the next-generation open source operating system independently developed and incompatible with Android.
The open atom open source foundation (hereinafter referred to as “the foundation”) accepted the code related to the basic capabilities of the intelligent terminal operating system donated by Huawei in September 2020, then opened the source, and named the open source project openatom openharmony (hereinafter referred to as “openharmony”) according to the naming rules. Organizations and individuals with global interest and need can participate in the project. So far, the project has more than 240 contributors, and the latest version is openharmony 2.0 canary.

Openharmony highlights
[open source, open everyone’s openharmony]

In December 2020, Botai, Huawei,, Runhe, yiketong, Software Institute of Chinese Academy of Sciences, China soft international and other seven units (ranked alphabetically) established the openharmony project group working committee under the organization of the foundation to start community governance of openharmony. As of May 2021, Taier laboratory, haoba technology, Huaqiu electronics, softcom power, spitto technology and other units of ICT Institute have successively negotiated to join the project group, and are completing the agreement signing and donation process.

Open source project openharmony 2.0

The major issues of openharmony open source project are jointly decided by the representatives of all member units of the working committee by voting. The voting rights are equal, one unit has one vote, and follow the open and clear management system rules of openharmony project group. According to the agreed rules and procedures, contributors can contribute code in the gitee community of openharmony open source project at any time, and the foundation organizes version release regularly.
The version decision follows the clear and open openharmony project group management system, and the road signs and version plans are determined by openharmony   PMC Project Management Committee decided that the discussion process should be open and transparent. The version release is determined by the working committee of openharmony project group according to the rules of openharmony project group management system. At present, it is planned to output a new version every two months, and the public road sign plan has been released in the community.
Under the organization of the working committee of the openharmony project group, the community organizes contributions in the form of working groups, special interest groups and sub projects, such as education working group, light smart watch sub project, industrial application sub project (pre Research), automobile intelligent cockpit special interest group, visual programming special interest group, python language special interest group The application technology community organizations in many fields, such as the openharmony on riscv special interest group, have begun to take shape gradually under the organization of the project working committee, which are led by the head teams of relevant domestic industries. It is expected to quickly and widely improve the technical maturity and coverage of openharmony, and is expected to obtain a large-scale commercial installation in these fields.

[independently developed and incompatible with Android]
The traditional terminal OS is mainly for single terminal. The system developed based on the openharmony open source project is naturally oriented to the interconnection of all things and can run on all kinds of intelligent terminals, large and small.
The openharmony user application is developed based on the newly designed openharmony API / SDK, can run on the system developed based on the openharmony open source project, and can flow seamlessly between multiple terminals.
Openharmony program framework only supports the operation of openharmony user applications, and does not support the operation of user applications developed based on Android API / SDK.
In the era of interconnection of all things, the number of devices per capita is rising, and the diversity of devices and scenes makes application development more complex and richer. In this trend, application providers and users urgently need a new service provision method to make application development simpler and service acquisition and use more convenient.
Openharmony user application is a new application based on the concept of service atomization. Different from traditional end-user applications, openharmony user applications support cross-end migration and multi-end collaboration between openharmony devices, develop multi-end deployment at one time, and realize separation, combination and circulation.
Openharmony runs user applications in two forms: applications that need to be installed in the traditional way, and atomic services that provide specific functions without installation.
Atomization service is a future oriented service provided by openharmony. It has the characteristics of independent entry (for example, users can directly trigger it by clicking, touching and sweeping provided by the manufacturer) and support installation free (automatically installed by the system). The atomized service is developed based on the openharmony API and supports running on various types of terminal devices covered by the openharmony system.
The application package of openharmony is published in the form of APP pack (application package), which is composed of one or more haps and describing each HAP attribute. HAP is the deployment package of ability, and the openharmony application code is expanded around the ability component.
Ability is an abstraction of the capabilities of an application. An application can contain one or more abilities. Ability can be divided into two types: FA (feature ability) and PA (particle ability). FA / PA is the basic unit of application, which can realize specific business functions. FA has UI interface, while PA has no UI interface.
Openharmony is attracting more partners and developers to join with an open-source attitude. Openharmony will fully activate the creativity of China’s software industry. Both the industry and the public look forward to its rich and diversified development possibilities in the future.

[all fields · next generation]
Openharmony contains the complete capabilities required by the distributed operating system, including kernel layer, system service layer, framework layer and application layer. Based on the traditional single device system capability, openharmony creatively puts forward the concept of adapting multiple terminal forms based on the same set of system capability to support the operation on multiple terminal devices. For device developers, openharmony adopts a component-based design scheme, which can be flexibly adapted according to the resource capacity and business characteristics of the device to meet the requirements of different forms of terminal devices for the operating system. It can run resource limited devices and wearable devices at the level of 100 K, and can also run various intelligent devices with relatively rich memory resources above 100 m.
    So far, all parties have invested manpower and funds in the openharmony open source project and achieved results, and the openharmony ecology has begun to take shape. Many companies have launched a variety of products equipped with openharmony operating system, such as watches, microwave ovens, soybean milk machines, cooking machines, recording pens, set-top boxes, smart cars, etc. openharmony has become an important new force in the global intelligent terminal operating system. Under the background that the information and communication technology industry and digital economy have entered a new era, openharmony has expanded a new space for the interconnection of all things to reshape the ecology of the information industry, and opened a new world full of innovative opportunities for all walks of life.

You know what
Relationship between openharmony and harmony OS
Openharmony is an open source project incubated and operated by the foundation. So far, the project has 240 contributors. Huawei is a major contributor and user of the openharmony project. Huawei has contributed a lot of code to the openharmony project and will continue to contribute code to the openharmony open source project in the future.

What does Canary mean?
Canary means canary. Canary version is Canary version, which is a process version.
The term dictionary refers to the mining industry. In English, there is a sentence called canary in a coal mine. It is about a protective measure when workers go to the pit for mining. Because canaries are sensitive to harmful gases in mines, such as carbon monoxide, canaries will die before human beings find harmful gases, so that miners can find harmful gases and make timely protection.
