The OSGi Alliance (formerly known as the Open Services Gateway initiative - now an obsolete name) is an open standards organization founded in March 1999. The Alliance and its members have specified a Java-based service platform that can be remotely managed. The core part of the specifications is a framework that defines an application life cycle management model, a service registry, an Execution environment and Modules. Based on this framework, a large number of OSGi Layers, APIs, and Services have been defined. Image File history File links No higher resolution available. ...

OSGi Framework Scope

Classification: OSGi & System-Layering

The Framework implements a complete and dynamic component model, something that is missing in standalone Java/VM environments. Applications or components (coming in the form of bundles for deployment) can be remotely installed, started, stopped, updated and uninstalled without requiring a reboot; management of Java packages/classes is specified in great detail. Life cycle management is done via APIs which allow for remote downloading of management policies. The service registry allows bundles to detect the addition of new services, or the removal of services, and adapt accordingly.

Specification Process

The OSGi specification is developed by the members in an open process and made available to the public free of charge under the OSGi Specification License ^[1]. The OSGi Alliance has a compliance program that is open to members only. As of October 2007, the list of certified OSGi implementations contains six entries. Compliance can mean: Compliance (medicine), a patients (or doctors) adherence to a recommended course of treatment Compliance (physiology), a measure of stiffness in mechanical science and physiology Compliance (regulation), the act of adhering to, and demonstrating adherence to laws, regulations or policies, in management Category: ...

The Alliance has a Board of Directors which provides the organization's overall governance. OSGi Officers have various roles and responsibilities in supporting the Alliance. Technical work is conducted within Expert Groups (EGs) chartered by the Board of Directors, and non-technical work is conducted in various Working Groups and Committees. The technical work conducted within Expert Groups include developing specifications, reference implementations, and compliance tests. These Expert Groups, working together, have produced four major releases of the OSGi specifications (as of 2007).

There are dedicated Expert Groups for the Enterprise, Mobile, Vehicle and the Core Platform areas. The Enterprise Expert Group (EEG) is the newest EG and is addressing Enterprise / Server-side applications.

Community

In October 2003, Nokia, Motorola, IBM, ProSyst and other OSGi members formed a Mobile Expert Group (MEG) that will specify a MIDP-based service platform for the next generation of smart mobile phones, addressing some of the needs that CLDC cannot manage - other than CDC.

New in OSGi Release 4

The new features of OSGi R4 in brief are as follows :

• Powerful new modularization capabilities providing enhanced encapsulation of networked services that can share a single VM.
• Modularized class sharing and hiding of implementation details.
• Advanced handling of multiple versions of the same classes so old and new applications can execute within the same VM.
• Localization of OSGi bundle manifests enabling service deployment anywhere.
• Enhancements in security and policies: The new Conditional Permission Admin service provides an elegant and simple way to manage networked services securely. It also supports dynamic policies that can depend on external (custom) conditions. Combined with R4 support for digital signatures, this provides a central security solution to large deployments of products using the OSGi Service Platform.
• A Declarative Services specification that addresses memory footprint issues that can prevent small embedded devices from using a service oriented architecture to support multiple applications. Additionally, it significantly simplifies the service-oriented programming model by declaratively handling the dynamics of services.
• Compatibility with Release 3, requiring no changes for existing OSGi bundles, applications, or services.

Service Oriented Architecture (SOA) is a computer systems architectural style for creating and using business processes, packaged as services, throughout their lifecycle. ...
