Please Note that Joomla! V1.x and the OpenSEF component are neither under active development or supported by security updates. Therefore this approach to implementing a "multi-site" system is not recommended for ongoing use. However these pages will remain online for the moment to support anyone who has used this approach in the past.

This section describes the concepts and technical details of the implementation of a "multi-site" Joomla!† system – one where a single Joomla! V1.0.x installation delivers content for two or more web sites, which may even have entirely different domain names.

†Joomla! is open-source web publishing software (of the type frequently described as a Content management System or "CMS"). Further details of Joomla! are to be found at the project web site.

One gaping hole in the multi-site features of OpenSEF is that it
includes no facilities for varying the appearance of sub-sites. The
only option using standard Joomla! is to set up alternative templates
for each sub-site, and allocate these on a page-by-page basis using the
template management interface in the backend.
On a large and continuously changing site this is very difficult to
manage - it would be all too easy to forget to do this and have new
pages of a sub-site coming up looking like the main site in all but
name. So I have added some code to a basic template to change its
appearance automatically according to the sub-site on which the page
sites.
Here is how it's done...

Setting up OpenSEF to deliver multiple sites from one Joomla!
installation is not difficult, but there are a few ambiguous areas so I
have briefly documented the settings I have used.

All of the basic elements of site navigation - the home page, menus,
site map and "breadcrumb trail" (or pathway) - need some attention to
work properly for the main site and all of the sub-sites of an OpenSEF
multi-site installation.
