We present the results of a European research project which developed specifications for so-called Knowledge Content Objects (KCO) and for an attendant infrastructure, the Knowledge Content Carrier Architecture (KCCA). The work addresses the problem that while there are many standards for content and for meta data, there is at present, no suitable framework that enables organizations to manage knowledge alongside content, in a coherent manner. Our approach postulates the KCO as a common structural entity which can be recognized and manipulated by a KCCA enabled system.
