The OHF Project is comprised of several diverse components each targeting a specific healthcare domain or healthcare technology. As a collective, however, OHF made several project wide (cross-component) decisions.

• All OHF Components require Java 1.4.2 or later. Some components require Java 1.5 or later. OHF is in the process of migrating all components to Java 1.5. For more information on and to download/install the Java SDK or runtime, please see Java Downloads.
• All OHF Components require Eclipse SDK 3.2 or later. Some components requre Eclipse SDK 3.3 or later. For more information on and to download/install the Eclipse SDK, please see Eclipse Downloads.
• Milestone releases of several of the components can be downloaded from the OHF Downloads page. Code for all componets is availiable in the Eclipse CVS. To browse the content of the Eclipse CVS Repository, please see the View CVS page. For further guidance on how to obtain code from the Eclipse CVS can be found on the OHF Developer Resources.
