Hello, I'm writing a JSDL->classad-based JDL converter, and I have a question related to the interpretation of the jsdl:DataStaging element. According to the definition, the jsdl:DataStaging element may have two child elements (both of which are optional) jsdl:Source and jsdl:Target. As I understand: - if only the jsdl:Source child is given, the DataStaging element refers to a request to copy files TO the execution node; - if only the jsdl:Target child is given, the DataStaging element refers to a request to copy files FROM the execution node, upon job termination; - if both jsdl:Source AND jsdl:Target children are given, then the previous two cases are combined (first the file is staged in, and upon job termination is staged out). Now, I do not fully understand the meaning of having a DataStaging element without jsdl:Source nor jsdl:Target. How should we interpret this situation? Thanks in advance, Moreno. -- Moreno Marzolla INFN Sezione di Padova, via Marzolo 8, 35100 PADOVA, Italy EMail: moreno.marzolla@pd.infn.it Phone: +39 049 8277047 WWW : http://www.pd.infn.it/~marzolla Fax : +39 049 8756233
