This is the "Semantic Social Profile" template. It has been created by Semantic Social Profile extension and used to assign the semantic properties to user page when that page was updated.
Now the template is invisible but if you want you can alter the view by editing the template.
Note: if something go wrong check that Semantic MediaWiki and Semantic_Forms are installed.
The template should be called in the following format:
{{Semantic Social Profile |SSP name= |SSP e-mail= |SSP location city= |SSP location state= |SSP location country= |SSP location street= |SSP location zipcode= |SSP location coordinates= |SSP home city= |SSP home state= |SSP home country= |SSP homeplace= |SSP birthday= |SSP about me= |SSP occupation= |SSP schools= |SSP places= |SSP websites= |SSP interests= |SSP avatar= |SSP foes= |SSP friends= |SSP organization type= |SSP organization name= |SSP phone= }}
