The Lattice Portal will give access to all QCD data, such as generated lattice configurations
Replicated data (multi-site), global tree structured name space (like a local file system)
Replica catalog, using SQL database, replicated to multiple sites for fault tolerance
Browse by attributes as well as by name
Parallel file transfers (bbftp, gridftp, jparss,...)
Drag-n-drop between sites (gui)
Policy based replication (auto migrate between sites)
