This report investigates an implementation of STKM, a Spatio-Temporal sKeletonModel. STKM expands the Grid Component Model (GCM) with an innovative programmable approach to compose an application by combining component, workflow and skeleton concepts. We explore a projection of the model on top of SCA and its implementation using Tuscany Java SCA. Experimental results show the need and benefits of the high level of abstraction offered by STKM.
