Usability, the tri-wizard challenge: Recurring scenarios in the design of a healthgrid portal

Designing a HealthGrid portal combines particularly diverse challenges. The coordination of middleware and application layers is compounded by the difficulty of working across multiple specialist domains (neuroscience, magnetic resonance imaging, grid computing). The paper outlines some of the technical and human challenges encountered in the design of the NeuroGrid portal sharing clinical and image data in neuroscience.
