Hierarchy
From harmoni
The Harmoni Hierarchy OSID implementation provides the ability to store a mapping of the hierarchical relationship between ids.
Hierarchy OSID documents on the O.K.I. site:
Implementation Notes
Dependencies
The Hierarchy makes use of the Id service for generating Ids. The Id service must be accessible via the Services API, but otherwise follows the Id OSID.
OSID v3
In the upcoming OSID v3, Hierarchy will loose the DisplayName and Description attributes of nodes, leaving only the Ids. This new hierarchy will be used as the public face for accessing and traversing hierarchical relationships in a variety of contexts. A more general purpose Topology service will be added to provide a storage mechanism for relationship information that includes both nodes and edges.
See the OSID v3 guide for more information.
