HDS is a file-based hierarchical data system designed for the + storage of a wide variety of information. It is particularly + suited to the storage of large multi-dimensional arrays (with + their ancillary data) where efficient access is needed.
+HDS organises data into hierarchies, broadly similar to the + directory structure of a hierarchical filing system, but + contained within a single HDS container file. The + structures stored in these files are self-describing and + flexible; HDS supports modification and extension of structures + previously created, as well as deletion, copying, renaming, etc..
+All information stored in HDS files is portable between the + machines on which HDS is implemented. Thus, there are no format + conversion problems when moving between machines.
+The routines in this package may be used to perform operations + on any HDS data. In addition, HDS forms a toolkit for the + construction of higher level (more specialised) data structures + and the software which accesses them. HDS routines are + therefore invoked indirectly by many other items of Starlink + software.
+This library handles HDS files version 4 and below.
