Knowledge Plaza, also referred to as KP, is an Enterprise 2.0 web service for knowledge management, social knowledge management and enterprise bookmarking which combines social bookmarking, document management, wikis and an internal social network. It was initially designed as an information management tool for knowledge workers and is often used for collaborative research projects, market intelligence, information brokerage, etc.

The vendor's company, Whatever S.A., is based in Louvain-la-Neuve Science Park (Belgium), has offices in Paris (France) and partners in Italy, Spain, The Netherlands and the United Kingdom. In September 2013, it announced the acquisition of Swiss social publishing company Hyperweek.[1]

In an annual benchmark carried out by French consultancy firm Lecko (previously named USEO),[2] Knowledge Plaza is referred to as the pioneer of social knowledge management tools amongst the more generic family of enterprise social software. The analysis concludes that Knowledge Plaza strikes a balance between a traditional document management system and more community-orientated environments such as Jive SBS.

In March 2017, Knowledge Plaza changed its name to Elium.[3]


  • In May 2011, Knowledge Plaza received the "Belgian Start-up of the year" Award from Belgian's leading ICT Magazine Datanews.[4]

  • In June 2010, Knowledge Plaza won the prize for the most innovative knowledge management tool at the I-expo / KM Forum conference in Paris.[6]
  • In 2008, Knowledge Plaza and Whatever won the Prix Lionel Van den Bossche 2008 award given each year to a Belgian innovative enterprise.[7]


Knowledge Plaza applies a collective classification mechanism to all information formats including websites (like Delicious), as well as documents, contacts, e-mails, book references and wikis – as underlined by the comparison of enterprise bookmarking platforms.

Feature set:

  • Combined full-text social search and faceted navigation
  • Bookmarklet for adding/sharing/organizing websites
  • Pipelines for adding/sharing/organizing emails and their attachments
  • Workspaces and communities for various security/visibility settings
  • Collaborative content creation (wiki pages)
  • Full export and summary of information packages
  • Custom e-mail digests and alerts
  • Custom vertical search engines based on shared bookmarks
  • Tag management abilities that mix a company-defined taxonomy and user-generated folksonomy. KP's approach was described by Thomas Vander Wal as "working wonderfully".[8]
