Biomedical applications are perfect candidates for gridification:

• Biomedical applications are perfect candidates for gridification:

• Huge volumes of data (an hospital = several TB per year)
• Dissemination of data
• Collaborative work (health networks)
• Very hard requirements (e.g. response time)

• But

• Partially structured semantic data
• Very strong privacy issues
• → a perfect play field for researchers !
