  5. 5. Information Systems 5 Knowledge management trends – connecting human and technology orientation – moving from document repositories to distributed cloud services – moving from officially endorsed organizational knowledge management applications to global social software applications – moving from usage in specialized tasks of social software to the central concept for connecting resources and activities • How do we represent knowledge and connect activities, resources and people? Where are we going to ?

  14. 14. Information Systems Seite 14 • The paper identifies seven major concepts that are needed to foster knowledge exchange between social environments. • We showed how descriptions about knowledge activities could be collected by our exemplary set of metadata elements. • The value of the ontology is that we can now easily integrate data collected from different applications within one or several organizations. • This work represents an initial step of the development towards a potential standard. • The next steps are to perform a technical proof of concept and to elaborate how these collected data can be used for knowledge management. Conclusion and Outlook
