Abstract
A hierarchical set of records has multiple hierarchical levels and depths. Each of the records has a tag that is unique within the hierarchical set of records. A method for retrieving a record includes identifying one of the records in the hierarchical set and modifying the tag, thereby producing a key. The hierarchical set of records is indexed only once. A record is selected and retrieved based on the indexing which applies the key to the hierarchical set of the records.
