Pretty grown up for a 5 year old.  Here are some details that describe it’s status:

Lotus Sametime 7.5, WebSphere Portal 6.0, and the upcoming IBM Lotus Notes “Hannover” release are all based on the Eclipse open source framework, helping to nurture a rich ecosystem of partners around these offerings.

Just last week Lotus announced Expeditor, a development platform for creating Eclipse-based and Web 2.0 applications that enables enterprises to integrate existing and new applications and deliver a personalized user experience across a range of devices.

The Eclipse Process Framework (EPF) is a resource for guidance on software development stemming from IBM’s contribution of portions of the Rational Unified Process to the Eclipse Foundation.  It comes as no surprise that the EPF has emerged as a widely trusted source for developers worldwide, with thousands of downloads recorded since the first EPF assets became available in February 2006.

IBM this year contributed software to both Eclipse and Mozilla Corp. that allows developers to work with and debug Ajax applications.

Higgins, another new Eclipse project this year, is the code base upon which IBM, Novell and others will build commercial ID management software so that it can integrate and interoperate within organizations.

In May, the Eclipse Modeling Project was formed to focus on the evolution and promotion of model-based development. More recently, IBM partnered with Cisco, Intel and others to propose the COSMOS project, which aims to provide an extensible, standards-based platform upon which software developers can create specialized, differentiated and inter-operable offerings of tools for system management.

IBM, along with other storage industry players including Brocade, Cisco, CA, Emulex, Engenio, Fujitsu, McDATA, Network Appliance and Sun Microsystems, announced the Aperi Project in October 2005 to promote the simplified management of storage infrastructures through an open source community.  The mission of the Aperi project is to create a standards-based, open source storage management framework and to cultivate an open source community and ecosystem for complementary products, capabilities, and services around the framework.
