Gerd Lanfermann, Bettina Schnor, Edward Seidel
2003 Integrated Network Management VIII  
The Grid Object Description Language (GODsL) is a generic and extensible approach to unify the various aspects that an object on a Grid can have.  ...  While very sophisticated data models exist to describe and characterize e. g. compute capacities or web services, we will show that a general description, which combines all of these aspects, is needed  ...  Grid Object Description Language We propose Grid Objects as a general description of objects on a Grid. We call the structure to describe such an entity the Grid Object Description Language.  ...
