C ONCLUSIONS Research Objects capture information that is necessary for understanding the results of research investigations as well as the methods (workflows) used in those investigation We presented a model for specifying workflow research objects We specified how instances of that model can be encoded using semantic web technologies using standards such as Object Exchange and Reuse, and the Annotation Ontology 11 February DICoSE workshop
