Meanwhile,theactivitiesweresupportedbyERCIMasaworking grouponGrids,P2PandServicecomputing,retainingthenameofCoreGRID. Thisalsoensuressustainabilityofthenetwork,maintainingandextendingthe activecollaborationwithintheEuropeanGridandSOAresearchcommunity. Being personally involved in the activities of the CoreGRID Institute on Resource Management and Scheduling, I felt privileged by the possibilities in collaborating with so many excellent partners. The continuous interest inresearchcollaborationsleadtofruitfulandencouragingdiscussions. This demonstratesthatCoreGRIDachieveditsgoaltoformavividandsustainable EuropeanNetworkofExcellence. One outcome of these collaborations is the organization of this workshop and this seminar, and eventually the creation of this book. The proceedings showtheongoingresearchactivitiesaroundservicelevelagreementswhichare consideredoneofthecrucialhottopicsinmanagingservicesandinfrastructures.
