How is the procedure for reviewing/accrediting your? Does your need to be reviewed by individual organizations in EGEE? If the other in Asia wish to be trusted by EGEE, is separate review necessary? APGridPMA will accredit your. EGEE does t need to review/accredit your. Can your organization trust s in EGEE? How is the procedure for reviewing? Do you need to review all s in EGEE? EUGridPMA will accredit s. Both you and APGridPMA do t need to review/accredit s in EGEE. If you will launch a new that is expected to be trusted by organizations in EGEE, how should you design policy and practices of your? APGrid PMA provides minimum requirements. 14
