The "API15" namespace is an archived namespace. This page contains information for a Joomla! version which is no longer supported. It exists only as a historical reference, it will not be improved and its content may be incomplete and/or contain broken links.

The Joomla! Framework was an important part of the Joomla! CMS architecture in the versions 1.5 and 1.6. It was based on modern object-oriented design patterns that make the Joomla core highly maintainable and easily extendable. Between April and July 2011, the Framework was rebranded as the Joomla! Platform and is now being developed separately from the Joomla! CMS. The first version of the CMS to ship with the Platform was version 1.7. Third party developers benefit from the rich, and easily accessible functionality that the Joomla Framework provides.
