Possible improvementsPossible improvementsof the P-GRADE Portalof the P-GRADE Portal
1. Connect it to new type of services.2. Connect it to well-known services with different
technologies.3. Make it cooperate with information systems:
– Is a Grid-level information system necessary?• Can it be implemented at all?• What technology should it use?
– What technologies have/require grid-level information systems?
– How to connect the Portal with the different information systems?
