somewhat similar to Nodegoat (http://nodegoat.net/), Prosop seeks to make it easier for historians to organize their data.
"This project aims to offer a tool that will accomplish this goal. Prosop will combine a highly flexible database of names and demographic information with a user friendly, customizable, opensource interface. It will put the best features of social networking applications, collaborative wikis, geotagging, and data search and filtering at the service of social historians. Prosop is designed to meet the disciplinary requirements of professional historians, while remaining attractive to amateur historians and genealogists."
