The metadata, which is held in the filing system catalogue, is transparently and permanently associated with the file. Its a general mechanism: the system provides standard metadata for source files, executables etc. and the developer creates the metadata for, e.g. fixed field data files with keyed access. The only demerit is that it uses a rather ugly two level filing system. The UNIX/Linux equivalent would be to keep the meta-data in the file's inode alongside the access permissions and to modify the file copy and move operations to silently handle the metadata by duplicating that part of the inode as and when needed. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |
