SOBI2

Sigsiu Online Business Index 2 (also known as Sobi2) is an open source web directory component and content construction kit (CCK) for the Joomla! content management system (CMS). Sobi2 is written in PHP and requires the MySQL database environment for storage. It is best suited for low to medium-level traffic web-sites.

Sobi2 is an add-on to Joomla that makes it possible to run and manage a directory in a Joomla website. The core Joomla system offers a link component; it is limited. Sobi2 on the other hand has many features that make it stand out from other directory components. It can be used strictly as a web directory or as a directory to physical locations, like golf courses. It has built-in integration with Google Maps (API key from Google is required) and it has additional plug-ins available just for Sobi2.

Sobi2 works in Joomla! 1.5 native mode without the legacy plug-in enabled. The Joomla! 1.5 FTP-Layer won't be supported.

There is also the option of making certain features of the listing paid for or free. One could make listings free but charge for links to the websites. You have the option to decide all of this when you set up and manage the component. This is an extremely powerful component that could be used more many functions and is frequently updated.
