A socio-semantic system has a continuous process of eliciting crucial knowledge of a domain through semi-formal ontologies, taxonomies<http://en.wikipedia.org/wiki/Taxonomies> or folksonomies <http://en.wikipedia.org/wiki/Folksonomies>. http://en.wikipedia.org/wiki/Topic_Map The semantic expressivity <http://en.wikipedia.org/wiki/Expressive_power> of Topic Maps is, in many ways, equivalent to that of RDF<http://en.wikipedia.org/wiki/Resource_Description_Framework>, but the major differences are that Topic Maps (i) provide a higher level of semantic abstraction <http://en.wikipedia.org/wiki/Semantic_data_model> (providing a template of topics, associations and occurrences, while RDF only provides a template of two arguments linked by one relationship) and (hence) (ii) allow n-ary <http://en.wikipedia.org/wiki/N-ary#n-ary> relationships (hypergraphs<http://en.wikipedia.org/wiki/Hypergraph>) between any number of nodes, while RDF is limited to triplets<http://en.wikipedia.org/wiki/Tuple> . http://en.wikipedia.org/wiki/Computer_Supported_Cooperative_Work Over the years, CSCW researchers have identified a number of core dimensions of cooperative work. A non-exhaustive list includes: - *Awareness*: individuals working together need to be able to gain some level of shared knowledge about each other's activities.[5]<http://en.wikipedia.org/wiki/Computer_Supported_Cooperative_Work#cite_note-dourish92-4> - *Articulation work*: cooperating individuals must somehow be able to partition work into units, divide it amongst themselves and, after the work is performed, reintegrate it.[6]<http://en.wikipedia.org/wiki/Computer_Supported_Cooperative_Work#cite_note-schmidt92-5> [7]<http://en.wikipedia.org/wiki/Computer_Supported_Cooperative_Work#cite_note-strauss85-6> - *Appropriation* (or tailorability): how an individual or group adapts a technology to their own particular situation; the technology may be appropriated in a manner completely unintended by the designers.[8]<http://en.wikipedia.org/wiki/Computer_Supported_Cooperative_Work#cite_note-mackay90-7> [9]<http://en.wikipedia.org/wiki/Computer_Supported_Cooperative_Work#cite_note-dourish03-8> [10]<http://en.wikipedia.org/wiki/Computer_Supported_Cooperative_Work#cite_note-schmidt91-9> http://en.wikipedia.org/wiki/Stigmergy *Stigmergy* is a mechanism of indirect coordination<http://en.wikipedia.org/wiki/Coordination> between agents or actions. The principle is that the trace left in the environment<http://en.wikipedia.org/wiki/Natural_environment> by an action stimulates the performance of a next action, by the same or a different agent. -- P2P Foundation: http://p2pfoundation.net - http://blog.p2pfoundation.net Connect: http://p2pfoundation.ning.com; Discuss: http://lists.ourproject.org/cgi-bin/mailman/listinfo/p2p-foundation Updates: http://del.icio.us/mbauwens; http://friendfeed.com/mbauwens; http://twitter.com/mbauwens; http://www.facebook.com/mbauwens
