  1. Jean-Philippe Baud CERN/IT/GD Problems with SRM v 2.1 definitions

  2. Main problems (1) • Default values when optional arguments are missing, for example • fileStorageType in PrepareToGet • KeepSpace in ReleaseFiles • What to do if size of array of requests/paths is zero? • Recursive methods • What should be in fileStatuses for RequestToGet, Rmdir: original directory name or individual file names? • What should happen in case of error: best effort or stop at first error?

  3. Major problems (2) • SetPermission • One should be able to set permission for “group_owner” or set default ACLs on directories • Need better definition of • RemoveFiles/AbortFiles/ReleaseFiles • ReleaseSpace/CompactSpace • Role of ReleaseSpace force: releasing a permanent file ??? • Ls vs GetFileMetaData

  4. More detailed problems (1) • Written document does not match WSDL • Different names • Different types: long vs unsigned long for TSizeInBytes • isExtended flag is in doc but not in WSDL • Why specifying push/pull mode for PrepareToPut/PrepareToGet if remote access is not supported? • Meaning of isValid in TMetaDataSpace • TPermissionMode null in SetPermission  read ?? • Ls method: lifetimeleft is normally associated with a request??

  5. More detailed problems (2) • ExtendFileLifeTime: why returning 0 and not current lifetime if extension refused?
