Sobi2 is one of the first components for Joomla! with content construction support.
Already in 2006, as no one talks about CCK for the content management system Joomla! Sigsiu.NET developed a component for Joomla! which has content construction support. Designed as a business directory (online business index) Sobi2 could already be used for every kind of directory. Therefore everything what the operator of a website wants to get listed in a directory like companies, clubs, persons, shops or products can be created.
