This thesis considers concept mapping as a basis for sharing computer workspaces among collaborating partners. The hypermedia
paradigm is used both for linkages between concept maps, and for multimedia annotations. The work produced a C++ class library in
support of the relevant concept mapping and hypermedia techniques. The library was both motivated by and used to develop a shared
workspace Computer Supported Collaborative Work (CSCW) application called Accord. The software was targeted at a business
audience and was developed using iterative prototyping and field testing in a large oil company. Informal observation of users working on
their own business problems indicates they have no difficulty adopting to concept mapping paradigm.
