idSpace D2.3 – Semantic meta-model integration and transformations v2: idSpace Project Deliverable

This deliverable discusses an extended set of requirements for transformations and metamodel for creativity techniques. Based on the requirements, the deliverable provides refined meta-model. The metamodel allows for more advanced transforma-tion concepts besides the previously delivered graph transfor-mation approach for merging idea graphs. This includes produc-tion rules for generating new associations between ideas and managing transactional histories for exploring changes and evo-lutions of ideas. Finally, we discuss some preliminary experi-ments with the approach as well as service oriented implemen-tation with portlets and widgets in the Liferay portal.
