• Data can be accessed over multiple protocols

Federation of service providers

• Heterogeneous backend storage
• Common interfaces (Web, REST, POSIX, CDMI)
• Common AAI with Check-in
• Discovery of Datasets in the EGI DataHub

Smart caching

• Site A hosts data and computing resources
• Site B hosts only data
• Site X uses data from A and B without pre-staging
• Pre-staging can also be done using APIs
• Data is accessed locally “à la” POSIX with FUSE

Publication of datasets
