Abstract: As the need for Computing resources to carry out numerical simulations Of Quantum Chromodynamics (QCD) formulated on a lattice has increased significantly, efficient use of the generated data has become a major concern. To improve on this, groups plan to share their configurations on a worldwide level within the International Lattice DataGrid (ILDG). Doing so requires standardized description of the configurations, standards on binary file formats and common middleware interfaces. We describe the requirements and problems, and discuss solutions. Furthermore, an overview is given on the implementation of the LatFor DataGrid [http://www-zeutheii.desy.de/latfor/ ldg], a France/German/ltalian grid that will be one of the regional grids within the ILDG grid-of-grids concept.
